Description
[0001] The present invention relates to new
spiro[3H-indole-3,2'-pyrrolidin]-2(1H)-one compounds and
derivatives, and their use as inhibitors of MDM2-p53 interaction,
pharmaceutical compositions which contain compounds of this kind,
their use as medicaments, especially as agents for treatment and/or
prevention of oncological diseases and synthetic intermediates.
BACKGROUND OF THE INVENTION
[0002] The tumor suppressor protein p53 is a sequence specific
transcription factor and plays a central role in the regulation of
several cellular processes, including cell cycle and growth arrest,
apoptosis, DNA repair, senescence, angiogenesis, and innate
immunity. The Mouse Double Minute 2 (MDM2) protein (or its human
homolog also known as HDM2) acts to down-regulate p53 activity in
an auto-regulatory manner, and under normal cellular conditions
(absence of stress), the MDM2 protein serves to maintain p53
activity at low levels. MDM2 directly inhibits the transactivation
function of p53, exports p53 out of the nucleus, and promotes
proteasome-mediated degradation of p53 through its E3 ubiquitin
ligase activity.
[0003] Deregulation of the MDM2/p53 balance by overexpression of
MDM2 or by p53 mutation or loss leads to malignant transformation
of normal cells. Presently p53 is known to play a key role in
practically all types of human cancers, and the mutation or loss of
the p53 gene can be identified in more than 50% of all human
cancers worldwide. Analysis of 28 different types of human cancers
in nearly 4,000 human tumor samples showed that MDM2 is amplified
in 7% of human cancers and that MDM2 overexpression by
amplification and p53 mutations are largely mutually exclusive
(Momand et al., Nucleic Acid Res (1998) 26:3453-3459).
[0004] Because of the powerful tumor suppressor function of p53,
reactivation of p53 has been long sought as a potentially novel
cancer therapeutic strategy. In tumor harboring wild-type p53, MDM2
is the primary cellular inhibitor of p53 activity, and
overexpression of MDM2 was found in many human tumors. Since MDM2
inhibits p53 through a direct protein-protein interaction, blocking
this interaction using small molecules was pursued in several
academic and industrial pharmaceutical laboratories in the last
decade. A variety of non-peptide, drug-like small molecule as e.g.
imidazole compounds (e.g. Nutlins or RG7112), benzodiazepinedione
compounds, spirooxindole compounds (e.g. MI-219), substituted
piperidines, pyrrolidinone compounds (e.g. PXN820-dl) and
modifications thereof have been selected and designed in order to
block MDM2/p53 interaction as a means to reactivate p53 in cells
(Vassilev et al., Science (2004) 303:844-848; Grasberger et al., J
Med Chem (2005) 48:909-912; Parks et al., Bioorg Med Chem Lett
(2005) 15:765; Ding et al., J Am Soc (2005) 127:10130-10131; WO
2010/028862, U.S. Pat. No. 7,884,107, WO 2008/119741). A number of
potent MDM2/p53 inhibitors have been evaluated in animal models of
human cancer for their anti-tumor activity (Vassilev et al.,
Science (2004) 303:844-848; Tovar et al, Cancer Res (2013) 73 (8):
2587-2597; Ding et al, Journal of Medicinal Chemistry (2013) 56
(14): 5979-5983; Rew et al, Journal of Medicinal Chemistry (2012)
55: 4936-4954; Sun et al, Journal of Medicinal Chemistry (2014) 57
(4): 1454-1472).

RG7112, an inhibitor of the MDM2-p53 interaction, could be observed
in vitro and in vivo. In particular, RG-7112 showed cytotoxic
activity with lower median IC.sub.50 values for p53 wild-type vs.
p53 mutant cell lines (Carol et al., Pediatric Blood and Cancer
(2013) 60(4):633-641). Moreover, RG-7112 induced tumor growth
inhibition in solid tumor xenograft models and was particularly
efficacious in acute lymphoblastic leukemia (ALL) xenograft models
with mixed-lineage leukemia (MLL) rearrangement, (Carol et al.,
Pediatric Blood and Cancer (2013) 60(4):633-641). Additionally, the
antiproliferative and proapoptotic activity of RG7112 has been
observed in human acute myeloid leukemia (AML) and human prostate
tumor xenograft models harboring p53 wild-type (Tovar et al, Cancer
Res (2013) 73 (8): 2587-2597).
[0006] Accordingly, small molecule inhibitors of the MDM2 protein
interactions offer an important approach towards cancer therapy,
either as a single agent, or in combination with a broad variety of
anti-tumor therapies and thus, there is the need for further MDM2
inhibitors which can be useful in the treatment of cancer.
[0007] The following documents disclose spiro oxindole compounds as
inhibitors of MDM2-p53 interaction:

[0009] The aim of the present invention is to provide new compounds
which can be used for the prevention and/or treatment of a disease
and/or condition characterised by excessive or abnormal cell
proliferation, especially a disease and/or condition wherein the
inhibition of the interaction between MDM2 and p53 is of
therapeutic benefit.
[0010] The compounds according to the invention are characterised
by a powerful inhibitory effect on the interaction between MDM2 and
p53 and in turn a high efficacy against tumour cells, e.g.
osteosarcoma, ALL etc., which is mediated through the inhibition of
the interaction between MDM2 and p53. In addition to the inhibitory
effect and cellular potency the compounds show good PK properties
and selectivity against p53 mutant cell lines. Furthermore, they
have good metabolic stability and, in contrast to many compounds
known in the prior art, good chemical stability, i.e. they are for
example less prone to epimerisation, a problem identified for many
known representatives of spiro oxindoles in the prior art (see e.g.
Zhao et al. J. Am. Chem. Soc 2013, 135, 7223-7234; Shu et al. Org.
Process Res. Dev. 2013, 17, 247-256; WO 2012/065022).
DETAILED DESCRIPTION OF THE INVENTION
[0011] It has now been found that, surprisingly, the compounds
according to the invention act as inhibitors of the interaction of
specific proteins which are involved in controlling cell
proliferation. Thus, the compounds according to the invention may
be used for example for the treatment of diseases connected with
this protein-protein interaction and characterised by excessive or
abnormal cell proliferation.

Definitions
[0165] Terms not specifically defined herein should be given the
meanings that would be given to them by one of skill in the art in
light of the disclosure and the context. As used in the
specification, however, unless specified to the contrary, the
following terms have the meaning indicated and the following
conventions are adhered to:
[0166] The use of the prefix C.sub.x-y, wherein x and y each
represent a natural number (x<y), indicates that the chain or
ring structure or combination of chain and ring structure as a
whole, specified and mentioned in direct association, may consist
of a maximum of y and a minimum of x carbon atoms.
[0167] The indication of the number of members in groups that
contain one or more heteroatom(s) (e.g. heteroalkyl, heteroaryl,
heteroarylalkyl, heterocyclyl, heterocycylalkyl) relates to the
total number of atoms of all the ring members or chain members or
the total of all the ring and chain members.
[0168] The indication of the number of carbon atoms in groups that
consist of a combination of carbon chain and carbon ring structure
(e.g. cycloalkylalkyl, arylalkyl) relates to the total number of
carbon atoms of all the carbon ring and carbon chain members.
Obviously, a ring structure has at least three members.
[0169] In general, for groups comprising two or more subgroups
(e.g. heteroarylalkyl, heterocycylalkyl, cycloalkylalkyl,
arylalkyl) the last named subgroup is the radical attachment point,
for example, the substituent aryl-C.sub.1-6alkyl means an aryl
group which is bound to a C.sub.1-6alkyl group, the latter of which
is bound to the core or to the group to which the substituent is
attached.
[0170] Alkyl denotes monovalent, saturated hydrocarbon chains,
which may be present in both straight-chain (unbranched) and
branched form. If an alkyl is substituted, the substitution may
take place independently of one another, by mono- or
polysubstitution in each case, on all the hydrogen-carrying carbon
atoms.

nonyl, decyl etc. without any further definition are meant
saturated hydrocarbon groups with the corresponding number of
carbon atoms, wherein all isomeric forms are included.
[0174] The above definition for alkyl also applies if alkyl is a
part of another (combined) group such as for example
C.sub.x-yalkylamino or C.sub.x-yalkyloxy.
[0175] The term alkylene can also be derived from alkyl. Alkylene
is bivalent, unlike alkyl, and requires two binding partners.
Formally, the second valency is produced by removing a hydrogen
atom in an alkyl. Corresponding groups are for example --CH.sub.3
and --CH.sub.2--, --CH.sub.2CH.sub.3 and --CH.sub.2CH.sub.2-- or
>CHCH.sub.3 etc.

[0180] Unlike alkyl, alkenyl consists of at least two carbon atoms,
wherein at least two adjacent carbon atoms are joined together by a
C--C double bond and a carbon atom can only be part of one C--C
double bond. If in an alkyl as hereinbefore defined having at least
two carbon atoms, two hydrogen atoms on adjacent carbon atoms are
formally removed and the free valencies are saturated to form a
second bond, the corresponding alkenyl is formed.

1-methyl-prop-1-enyl, 1-methyl-prop-2-enyl etc.
[0183] Alkenyl may optionally be present in the cis or trans or E
or Z orientation with regard to the double bond(s).
[0184] The above definition for alkenyl also applies when alkenyl
is part of another (combined) group such as for example in
C.sub.x-yalkenylamino or C.sub.x-yalkenyloxy.
[0185] Unlike alkylene, alkenylene consists of at least two carbon
atoms, wherein at least two adjacent carbon atoms are joined
together by a C--C double bond and a carbon atom can only be part
of one C--C double bond. If in an alkylene as hereinbefore defined
having at least two carbon atoms, two hydrogen atoms at adjacent
carbon atoms are formally removed and the free valencies are
saturated to form a second bond, the corresponding alkenylene is
formed.

etc.
[0187] By the generic terms propenylene, butenylene, pentenylene,

atoms, i.e. propenylene includes 1-methylethenylene and butenylene
includes 1-methylpropenylene, 2-methylpropenylene,
1,1-dimethylethenylene and 1,2-dimethylethenylene.
[0188] Alkenylene may optionally be present in the cis or trans or
E or Z orientation with regard to the double bond(s).
[0189] The above definition for alkenylene also applies when
alkenylene is a part of another (combined) group as for example in
HO--C.sub.x-yalkenyleneamino or
H.sub.2N--C.sub.x-yalkenyleneoxy.
[0190] Unlike alkyl, alkynyl consists of at least two carbon atoms,
wherein at least two adjacent carbon atoms are joined together by a
C--C triple bond. If in an alkyl as hereinbefore defined having at
least two carbon atoms, two hydrogen atoms in each case at adjacent
carbon atoms are formally removed and the free valencies are
saturated to form two further bonds, the corresponding alkynyl is
formed.
[0191] Examples of alkynyl are ethynyl, prop-1-ynyl, prop-2-ynyl,
but-1-ynyl, but-2-ynyl, but-3-ynyl, 1-methyl-prop-2-ynyl,

[0192] By the generic terms propynyl, butynyl, pentynyl, hexynyl,

but-2-ynyl, but-3-ynyl, 1-methyl-prop-1-ynyl, 1-methyl-prop-2-ynyl,
etc.
[0193] If a hydrocarbon chain carries both at least one double bond
and also at least one triple bond, by definition it belongs to the
alkynyl subgroup.
[0194] The above definition for alkynyl also applies if alkynyl is
part of another (combined) group, as for example in
C.sub.x-yalkynylamino or C.sub.x-yalkynyloxy.
[0195] Unlike alkylene, alkynylene consists of at least two carbon
atoms, wherein at least two adjacent carbon atoms are joined
together by a C--C triple bond. If in an alkylene as hereinbefore
defined having at least two carbon atoms, two hydrogen atoms in
each case at adjacent carbon atoms are formally removed and the
free valencies are saturated to form two further bonds, the
corresponding alkynylene is formed.
[0196] Examples of alkynylene are ethynylene, propynylene,
1-methylethynylene, butynylene, 1-methylpropynylene,
1,1-dimethylethynylene, 1,2-dimethylethynylene, pentynylene,

1,2-dimethylpropynylene, 1,3-dimethylpropynylene, hexynylene
etc.
[0197] By the generic terms propynylene, butynylene, pentynylene,
hexynylene etc. without any further definition are meant all the
conceivable isomeric forms with the corresponding number of carbon
atoms, i.e. propynylene includes 1-methylethynylene and butynylene
includes 1-methylpropynylene, 2-methylpropynylene,
1,1-dimethylethynylene and 1,2-dimethylethynylene.
[0198] The above definition for alkynylene also applies if
alkynylene is part of another (combined) group, as for example in
HO--C.sub.x-yalkynyleneamino or
H.sub.2N--C.sub.x-yalkynyleneoxy.
[0199] By heteroatoms are meant oxygen, nitrogen and sulphur
atoms.
[0200] Haloalkyl (haloalkenyl, haloalkynyl) is derived from the
previously defined alkyl (alkenyl, alkynyl) by replacing one or
more hydrogen atoms of the hydrocarbon chain independently of one
another by halogen atoms, which may be identical or different. If a
haloalkyl (haloalkenyl, haloalkynyl) is to be further substituted,
the substitutions may take place independently of one another, in
the form of mono- or polysubstitutions in each case, on all the
hydrogen-carrying carbon atoms.
[0201] Examples of haloalkyl (haloalkenyl, haloalkynyl) are
--CF.sub.3, --CHF.sub.2, --CH.sub.2F, --CF.sub.2CF.sub.3,
--CHFCF.sub.3, --CH.sub.2CF.sub.3, --CF.sub.2CH.sub.3,
--CHFCH.sub.3, --CF.sub.2CF.sub.2CF.sub.3,
--CF.sub.2CH.sub.2CH.sub.3, --CF.dbd.CF.sub.2, --CCl.dbd.CH.sub.2,
--CBr.dbd.CH.sub.2, --C.ident.C--CF.sub.3, --CHFCH.sub.2CH.sub.3,
--CHFCH.sub.2CF.sub.3 etc.
[0202] From the previously defined haloalkyl (haloalkenyl,
haloalkynyl) are also derived the terms haloalkylene
(haloalkenylene, haloalkynylene). Haloalkylene (haloalkenylene,
haloalkynylene), unlike haloalkyl (haloalkenyl, haloalkynyl), is
bivalent and requires two binding partners. Formally, the second
valency is formed by removing a hydrogen atom from a haloalkyl
(haloalkenyl, haloalkynyl).
[0203] Corresponding groups are for example --CH.sub.2F and
--CHF--, --CHFCH.sub.2F and --CHFCHF-- or >CFCH.sub.2F etc.
[0204] The above definitions also apply if the corresponding
halogen-containing groups are part of another (combined) group.
[0205] Halogen relates to fluorine, chlorine, bromine and/or iodine
atoms.
[0206] Cycloalkyl is made up of the subgroups monocyclic
hydrocarbon rings, bicyclic hydrocarbon rings and spiro-hydrocarbon
rings. The systems are saturated. In bicyclic hydrocarbon rings two
rings are joined together so that they have at least two carbon
atoms together. In spiro-hydrocarbon rings one carbon atom
(spiroatom) belongs to two rings together.
[0207] If a cycloalkyl is to be substituted, the substitutions may
take place independently of one another, in the form of mono- or
polysubstitutions in each case, on all the hydrogen-carrying carbon
atoms. Cycloalkyl itself may be linked as a substituent to the
molecule via every suitable position of the ring system.
[0208] Examples of cycloalkyl are cyclopropyl, cyclobutyl,
cyclopentyl, cyclohexyl, cycloheptyl, bicyclo[2.2.0]hexyl,
bicyclo[3.2.0]heptyl, bicyclo[3.2.1]octyl, bicyclo[2.2.2]octyl,
bicyclo[4.3.0]nonyl (octahydroindenyl), bicyclo[4.4.0]decyl
(decahydronaphthyl), bicyclo[2.2.1]heptyl (norbornyl),
bicyclo[4.1.0]heptyl (norcaranyl), bicyclo[3.1.1]heptyl (pinanyl),
spiro[2.5]octyl, spiro[3.3]heptyl etc.
[0209] The above definition for cycloalkyl also applies if
cycloalkyl is part of another (combined) group as for example in
C.sub.x-ycycloalkylamino, C.sub.x-ycycloalkyloxy or
C.sub.x-ycycloalkylalkyl.
[0210] If the free valency of a cycloalkyl is saturated, then an
alicyclic group is obtained.
[0211] The term cycloalkylene can thus be derived from the
previously defined cycloalkyl. Cycloalkylene, unlike cycloalkyl, is
bivalent and requires two binding partners. Formally, the second
valency is obtained by removing a hydrogen atom from a cycloalkyl.
Corresponding groups are for example:
##STR00010##
[0212] The above definition for cycloalkylene also applies if
cycloalkylene is part of another (combined) group as for example in
HO--C.sub.x-ycycloalkyleneamino or
H.sub.2N--C.sub.x-ycycloalkyleneoxy.
[0213] Cycloalkenyl is also made up of the subgroups monocyclic
hydrocarbon rings, bicyclic hydrocarbon rings and spiro-hydrocarbon
rings. However, the systems are unsaturated, i.e. there is at least
one C--C double bond but no aromatic system. If in a cycloalkyl as
hereinbefore defined two hydrogen atoms at adjacent cyclic carbon
atoms are formally removed and the free valencies are saturated to
form a second bond, the corresponding cycloalkenyl is obtained.
[0214] If a cycloalkenyl is to be substituted, the substitutions
may take place independently of one another, in the form of mono-
or polysubstitutions in each case, on all the hydrogen-carrying
carbon atoms. Cycloalkenyl itself may be linked as a substituent to
the molecule via every suitable position of the ring system.
[0215] Examples of cycloalkenyl are cycloprop-1-enyl,
cycloprop-2-enyl, cyclobut-1-enyl, cyclobut-2-enyl,
cyclopent-1-enyl, cyclopent-2-enyl, cyclopent-3-enyl,
cyclohex-1-enyl, cyclohex-2-enyl, cyclohex-3-enyl,
cyclohept-1-enyl, cyclohept-2-enyl, cyclohept-3-enyl,
cyclohept-4-enyl, cyclobuta-1,3-dienyl, cyclopenta-1,4-dienyl,
cyclopenta-1,3-dienyl, cyclopenta-2,4-dienyl, cyclohexa-1,3-dienyl,
cyclohexa-1,5-dienyl, cyclohexa-2,4-dienyl, cyclohexa-1,4-dienyl,
cyclohexa-2,5-dienyl, bicyclo[2.2.1]hepta-2,5-dienyl
(norborna-2,5-dienyl), bicyclo[2.2.1]hept-2-enyl (norbornenyl),
spiro[4,5]dec-2-enyl etc.
[0216] The above definition for cycloalkenyl also applies when
cycloalkenyl is part of another (combined) group as for example in
C.sub.x-ycycloalkenylamino, C.sub.x-ycycloalkenyloxy or
C.sub.x-ycycloalkenylalkyl.
[0217] If the free valency of a cycloalkenyl is saturated, then an
unsaturated alicyclic group is obtained.
[0218] The term cycloalkenylene can thus be derived from the
previously defined cycloalkenyl. Cycloalkenylene, unlike
cycloalkenyl, is bivalent and requires two binding partners.
Formally, the second valency is obtained by removing a hydrogen
atom from a cycloalkenyl. Corresponding groups are for example:
##STR00011##
[0219] The above definition for cycloalkenylene also applies if
cycloalkenylene is part of another (combined) group as for example
in HO--C.sub.x-ycloalkenyleneamino or
H.sub.2N--C.sub.x-ycycloalkenyleneoxy.
[0220] Aryl denotes mono-, bi- or tricyclic carbocycles with at
least one aromatic carbocycle. Preferably, it denotes a monocyclic
group with six carbon atoms (phenyl) or a bicyclic group with nine
or ten carbon atoms (two six-membered rings or one six-membered
ring with a five-membered ring), wherein the second ring may also
be aromatic or, however, may also be partially saturated.
[0221] If an aryl is to be substituted, the substitutions may take
place independently of one another, in the form of mono- or
polysubstitutions in each case, on all the hydrogen-carrying carbon
atoms. Aryl itself may be linked as a substituent to the molecule
via every suitable position of the ring system.
[0222] Examples of aryl are phenyl, naphthyl, indanyl
(2,3-dihydroindenyl), indenyl, anthracenyl, phenanthrenyl,
tetrahydronaphthyl (1,2,3,4-tetrahydronaphthyl, tetralinyl),
dihydronaphthyl (1,2-dihydronaphthyl), fluorenyl etc.
[0223] The above definition of aryl also applies if aryl is part of
another (combined) group as for example in arylamino, aryloxy or
arylalkyl.
[0224] If the free valency of an aryl is saturated, then an
aromatic group is obtained.
[0225] The term arylene can also be derived from the previously
defined aryl. Arylene, unlike aryl, is bivalent and requires two
binding partners. Formally, the second valency is formed by
removing a hydrogen atom from an aryl. Corresponding groups are for
example:
##STR00012##
[0226] The above definition for arylene also applies if arylene is
part of another (combined) group as for example in HO-aryleneamino
or H.sub.2N-aryleneoxy.
[0227] Heterocyclyl denotes ring systems, which are derived from
the previously defined cycloalkyl, cycloalkenyl and aryl by
replacing one or more of the groups --CH.sub.2-- independently of
one another in the hydrocarbon rings by the groups --O--, --S-- or
--NH-- or by replacing one or more of the groups --CH-- by the
group --N--, wherein a total of not more than five heteroatoms may
be present, at least one carbon atom must be present between two
oxygen atoms and between two sulphur atoms or between an oxygen and
a sulphur atom and the ring as a whole must have chemical
stability. Heteroatoms may optionally be present in all the
possible oxidation stages (sulphur.fwdarw.sulphoxide --SO--,
sulphone --SO.sub.2--; nitrogen.fwdarw.N-oxide). In a heterocyclyl
there is ng heteroaromatic ring, i.e. no heteroatom is part of an
aromatic system.
[0228] A direct result of the derivation from cycloalkyl,
cycloalkenyl and aryl is that heterocyclyl is made up of the
subgroups monocyclic heterorings, bicyclic heterorings, tricyclic
heterorings and spiro-heterorings, which may be present in
saturated or unsaturated form.
[0229] By unsaturated is meant that there is at least one double
bond in the ring system in question, but no heteroaromatic system
is formed. In bicyclic heterorings two rings are linked together so
that they have at least two (hetero)atoms in common. In
spiro-heterorings one carbon atom (spiroatom) belongs to two rings
together.
[0230] If a heterocyclyl is substituted, the substitutions may take
place independently of one another, in the form of mono- or
polysubstitutions in each case, on all the hydrogen-carrying carbon
and/or nitrogen atoms. Heterocyclyl itself may be linked as a
substituent to the molecule via every suitable position of the ring
system.
[0231] Examples of heterocyclyl are tetrahydrofuryl, pyrrolidinyl,
pyrrolinyl, imidazolidinyl, thiazolidinyl, imidazolinyl,
pyrazolidinyl, pyrazolinyl, piperidinyl, piperazinyl, oxiranyl,
aziridinyl, azetidinyl, 1,4-dioxanyl, azepanyl, diazepanyl,
morpholinyl, thiomorpholinyl, homomorpholinyl, homopiperidinyl,
homopiperazinyl, homothiomorpholinyl, thiomorpholinyl-S-oxide,
thiomorpholinyl-S,S-dioxide, 1,3-dioxolanyl, tetrahydropyranyl,
tetrahydrothiopyranyl, [1,4]-oxazepanyl, tetrahydrothienyl,
homothiomorpholinyl-S,S-dioxide, oxazolidinonyl, dihydropyrazolyl,
dihydropyrrolyl, dihydropyrazinyl, dihydropyridyl,
dihydro-pyrimidinyl, dihydrofuryl, dihydropyranyl,
tetrahydrothienyl-S-oxide, tetrahydrothienyl-S,S-dioxide,
homothiomorpholinyl-S-oxide, 2,3-dihydroazet, 2H-pyrrolyl,
4H-pyranyl, 1,4-dihydropyridinyl, 8-aza-bicyclo[3.2.1]octyl,
8-aza-bicyclo[5.1.0]octyl, 2-oxa-5-azabicyclo[2.2.1]heptyl,
8-oxa-3-aza-bicyclo[3.2.1]octyl, 3,8-diaza-bicyclo[3.2.1]octyl,
2,5-diaza-bicyclo[2.2.1]heptyl, 1-aza-bicyclo[2.2.2]octyl,
3,8-diaza-bicyclo[3.2.1]octyl, 3,9-diaza-bicyclo[4.2.1]nonyl,
2,6-diaza-bicyclo[3.2.2]nonyl, 1,4-dioxa-spiro[4.5]decyl,
1-oxa-3,8-diaza-spiro[4.5]decyl, 2,6-diaza-spiro[3.3]heptyl,
2,7-diaza-spiro[4.4]nonyl, 2,6-diaza-spiro[3.4]octyl,
3,9-diaza-spiro[5.5]undecyl, 2.8-diaza-spiro[4,5]decyl etc.
[0232] Further examples are the structures illustrated below, which
may be attached via each hydrogen-carrying atom (exchanged for
hydrogen):
##STR00013## ##STR00014## ##STR00015##
[0233] Preferably, heterocyclyls are 4 to 8 membered, monocyclic
and have one or two heteroatoms independently selected from oxygen,
nitrogen and sulfur Preferred heterocyclyls are: piperazinyl,
piperidinyl, morpholinyl, pyrrolidinyl, azetidinyl,
tetrahydropyranyl, tetrahydrofuranyl.
[0234] The above definition of heterocyclyl also applies if
heterocyclyl is part of another (combined) group as for example in
heterocyclylamino, heterocyclyloxy or heterocyclylalkyl.
[0235] If the free valency of a heterocyclyl is saturated, then a
heterocyclic group is obtained.
[0236] The term heterocyclylene is also derived from the previously
defined heterocyclyl. Heterocyclylene, unlike heterocyclyl, is
bivalent and requires two binding partners. Formally, the second
valency is obtained by removing a hydrogen atom from a
heterocyclyl. Corresponding groups are for example:
##STR00016##
[0237] The above definition of heterocyclylene also applies if
heterocyclylene is part of another (combined) group as for example
in HO-heterocyclyleneamino or H.sub.2N-heterocyclyleneoxy.
[0238] Heteroaryl denotes monocyclic heteroaromatic rings or
polycyclic rings with at least one heteroaromatic ring, which
compared with the corresponding aryl or cycloalkyl (cycloalkenyl)
contain, instead of one or more carbon atoms, one or more identical
or different heteroatoms, selected independently of one another
from the group consisting of nitrogen, sulphur and oxygen, wherein
the resulting group must be chemically stable. The prerequisite for
the presence of heteroaryl is a heteroatom and a heteroaromatic
system.
[0239] If a heteroaryl is to be substituted, the substitutions may
take place independently of one another, in the form of mono- or
polysubstitutions in each case, on all the hydrogen-carrying carbon
and/or nitrogen atoms. Heteroaryl itself may be linked as a
substituent to the molecule via every suitable position of the ring
system, both carbon and nitrogen.
[0240] Examples of heteroaryl are furyl, thienyl, pyrrolyl,
oxazolyl, thiazolyl, isoxazolyl, isothiazolyl, pyrazolyl,
imidazolyl, triazolyl, tetrazolyl, oxadiazolyl, thiadiazolyl,
pyridyl, pyrimidyl, pyridazinyl, pyrazinyl, triazinyl,
pyridyl-N-oxide, pyrrolyl-N-oxide, pyrimidinyl-N-oxide,
pyridazinyl-N-oxide, pyrazinyl-N-oxide, imidazolyl-N-oxide,
isoxazolyl-N-oxide, oxazolyl-N-oxide, thiazolyl-N-oxide,
oxadiazolyl-N-oxide, thiadiazolyl-N-oxide, triazolyl-N-oxide,
tetrazolyl-N-oxide, indolyl, isoindolyl, benzofuryl, benzothienyl,
benzoxazolyl, benzothiazolyl, benzisoxazolyl, benzisothiazolyl,
benzimidazolyl, indazolyl, isoquinolinyl, quinolinyl, quinoxalinyl,
cinnolinyl, phthalazinyl, quinazolinyl, benzotriazinyl,
indolizinyl, oxazolopyridyl, imidazopyridyl, naphthyridinyl,
benzoxazolyl, pyridopyridyl, pyrimidopyridyl, purinyl, pteridinyl,
benzothiazolyl, imidazopyridyl, imidazothiazolyl,
quinolinyl-N-oxide, indolyl-N-oxide, isoquinolyl-N-oxide,
quinazolinyl-N-oxide, quinoxalinyl-N-oxide, phthalazinyl-N-oxide,
indolizinyl-N-oxide, indazolyl-N-oxide, benzothiazolyl-N-oxide,
benzimidazolyl-N-oxide etc.
[0241] Further examples are the structures illustrated below, which
may be attached via each hydrogen-carrying atom (exchanged for
hydrogen):
##STR00017## ##STR00018##
[0242] Preferably, heteroaryls are 5-6 membered monocyclic or 9-10
membered bicyclic, each with 1 to 4 heteroatoms independently
selected from oxygen, nitrogen and sulfur.
[0243] The above definition of heteroaryl also applies if
heteroaryl is part of another (combined) group as for example in
heteroarylamino, heteroaryloxy or heteroarylalkyl.
[0244] If the free valency of a heteroaryl is saturated, a
heteroaromatic group is obtained.
[0245] The term heteroarylene is also derived from the previously
defined heteroaryl. Heteroarylene, unlike heteroaryl, is bivalent
and requires two binding partners. Formally, the second valency is
obtained by removing a hydrogen atom from a heteroaryl.
Corresponding groups are for example:
##STR00019##
[0246] The above definition of heteroarylene also applies if
heteroarylene is part of another (combined) group as for example in
HO-heteroaryleneamino or H.sub.2N-heteroaryleneoxy.
[0247] By substituted is meant that a hydrogen atom which is bound
directly to the atom under consideration, is replaced by another
atom or another group of atoms (substituent). Depending on the
starting conditions (number of hydrogen atoms) mono- or
polysubstitution may take place on one atom. Substitution with a
particular substituent is only possible if the permitted valencies
of the substituent and of the atom that is to be substituted
correspond to one another and the substitution leads to a stable
compound (i.e. to a compound which is not converted spontaneously,
e.g. by rearrangement, cyclisation or elimination).
[0248] Bivalent substituents such as --S, --NR, --NOR, .dbd.NNRR,
--NN(R)C(O)NRR, --N.sub.2 or the like, may only be substituents on
carbon atoms, wherein the bivalent substituent .dbd.O may also be a
substituent on sulphur. Generally, substitution may be carried out
by a bivalent substituent only at ring systems and requires
replacement of two geminal hydrogen atoms, i.e. hydrogen atoms that
are bound to the same carbon atom that is saturated prior to the
substitution. Substitution by a bivalent substituent is therefore
only possible at the group --CH.sub.2-- or sulphur atoms (.dbd.O
only) of a ring system.

correspondences are listed below:
##STR00020##
[0258] If for example in the sequence X--Y--Z the component Y is
supposed to correspond to the structural section --N.dbd., this
means both X--N--Z and also X--N--Z.
[0259] In a representation such as for example
##STR00021##
the dotted line means that the ring system may be attached to the
molecule via the carbon atom 1 or 2, and is thus equivalent to the
following representation
##STR00022##
[0260] In a representation such as for example
##STR00023##
the letter A has the function of a ring designation in order to
make it easier, for example, to indicate the attachment of the ring
in question to other rings.
[0261] For bivalent groups in which it is crucial to determine
which adjacent groups they bind and with which valency, the
corresponding binding partners are indicated in brackets where
necessary for clarification purposes, as in the following
representations:
##STR00024##
or (R.sup.2) --C(O)NH-- or (R.sup.2) --NHC(O)--;
[0262] Groups or substituents are frequently selected from the
group consisting of a number of alternative groups/substituents
with a corresponding group designation (e.g. R.sup.a, R.sup.b etc).
If such a group is used repeatedly to define a compound according
to the invention in different parts of the molecule, it is pointed
out that the various uses are to be regarded as totally independent
of one another.
[0263] By a therapeutically effective amount for the purposes of
this invention is meant a quantity of substance that is capable of
obviating symptoms of illness or of preventing or alleviating these
symptoms, or which prolong the survival of a treated patient.

[0265] Features and advantages of the present invention will become
apparent from the following detailed examples which illustrate the
principles of the invention by way of example without restricting
its scope:
Preparation of the Compounds According to the Invention
[0266] General
[0267] Unless stated otherwise, all the reactions are carried out
in commercially obtainable apparatus using methods that are
commonly used in chemical laboratories. Starting materials that are
sensitive to air and/or moisture are stored under protective gas
and corresponding reactions and manipulations therewith are carried
out under protective gas (nitrogen or argon).
[0268] The compounds according to the invention are named in
accordance with CAS rules using the software Autonom (Beilstein).
If a compound is to be represented both by a structural formula and
by its nomenclature, in the event of a conflict the structural
formula is decisive.
[0269] Microwave reactions are carried out in an initiator/reactor
made by Biotage or in an Explorer made by CEM or in Synthos 3000 or
Monowave 3000 made by Anton Paar in sealed containers (preferably
2, 5 or 20 mL), preferably with stirring.
[0270] Chromatography
[0271] The thin layer chromatography is carried out on ready-made
silica gel 60 TLC plates on glass (with fluorescence indicator
F-254) made by Merck.
[0272] The preparative high pressure chromatography (RP HPLC) of
the example compounds according to the invention is carried out on
Agilent or Gilson systems with columns made by Waters (names:
SunFire.TM. Prep C18, OBD.TM. 10 .mu.m, 50.times.150 mm or
SunFire.TM. Prep C18 OBD.TM. 5 .mu.m, 30.times.50 mm or XBridge.TM.
Prep C18, OBD.TM. 10 .mu.m, 50.times.150 mm or XBridge.TM. Prep
C18, OBD.TM. 5 .mu.m, 30.times.150 mm or XBridge.TM. Prep C18,
OBD.TM. 5 .mu.m, 30.times.50 mm) and YMC (names: Actus-Triart Prep
C18, 5 .mu.m, 30.times.50 mm).
[0273] Different gradients of H.sub.2O/acetonitrile are used to
elute the compounds, while for Agilent systems 5% acidic modifier
(20 mL HCOOH to 1 L H.sub.2O/acetonitrile (1/1)) is added to the
water (acidic conditions). For Gilson systems the water is added
0.1% HCOOH.
[0274] For the chromatography under basic conditions for Agilent
systems H.sub.2O/acetonitrile gradients are used as well, while the
water is made akaline by addition of 5% basic modifier (50 g
NH.sub.4HCO.sub.3+50 mL NH.sub.3 (25% in H.sub.2O) to 1 L with
H.sub.2O). For Gilson systems the water is made alkaline as
follows: 5 mL NH.sub.4HCO.sub.3 solution (158 g in 1 L H.sub.2O)
and 2 mL NH.sub.3 (28% in H.sub.2O) are replenished to 1 L with
H.sub.2O.
[0275] The supercritical fluid chromatography (SFC) of the
intermediates and example compounds according to the invention is
carried out on a JASCO SFC-system with the following columns:
Chiralcel OJ (250.times.20 mm, 5 .mu.m), Chiralpak AD (250.times.20
mm, 5 .mu.m), Chiralpak AS (250.times.20 mm, 5 .mu.m), Chiralpak IC
(250.times.20 mm, 5 .mu.m), Chiralpak IA (250.times.20 mm, 5
.mu.m), Chiralcel OJ (250.times.20 mm, 5 .mu.m), Chiralcel OD
(250.times.20 mm, 5 .mu.m), Phenomenex Lux C2 (250.times.20 mm, 5
.mu.m).
[0276] The analytical HPLC (reaction control) of intermediate
compounds is carried out using columns made by Waters (names:
XBridge.TM. C18, 2.5 .mu.m, 2.1.times.20 mm or XBridge.TM. C18, 2.5
.mu.m, 2.1.times.30 mm) and YMC (names: Triart C18, 3.0 .mu.m,
2.0.times.30 mm). The analytical equipment is also equipped with a
mass detector in each case.
[0277] HPLC-Mass Spectroscopy/UV-Spectrometry
[0278] The retention times/MS-ESI.sup.+ for characterizing the
example compounds according to the invention are produced using an
HPLC-MS apparatus (high performance liquid chromatography with mass
detector). Compounds that elute at the injection peak are given the
retention time t.sub.Ret.=0.00.

[0289] The compounds according to the invention are prepared by the
methods of synthesis described hereinafter in which the
substituents of the general formulae have the meanings given
hereinbefore. These methods are intended as an illustration of the
invention without restricting its subject matter and the scope of
the compounds claimed to these examples. Where the preparation of
starting compounds is not described, they are commercially
obtainable or may be prepared analogously to known prior art
compounds or methods described herein. Substances described in the
literature are prepared according to the published methods of
synthesis.
[0290] General Reaction Scheme and Summary of the Synthesis
Route
##STR00025##
##STR00026##
##STR00027##
##STR00028##
[0291] Novel compounds of structure (I) can be prepared stepwise
starting with a synthesis route depicted in scheme 1 from compounds
A-1 via a decarboxylative 1,3 dipolar cycloaddition with an amino
acid A-2 (method A) or A-6 (method D) and a nitro ethene A-3 to
build up spiro systems A-4 and A-7 as a racemic mixture potentially
along with other regio- and/or diastereoisomers of A-4 and A-7. The
enantiomers of A-4 and A-7 can be separated at this stage by chiral
SFC or alternatively the racemic mixture can be separated at any
later stage of the synthesis. Also all other means known for
separation of enantiomers can be applied here or after any later
synthetic step herein described, e.g. crystallisation, chiral
resolution, chiral HPLC etc. (see also Enantiomers, racemates, and
resolutions, Jean Jacques, Andre Collet, Samuel H Wilen John Wiley
and Sons, N Y, 1981).
[0292] A-4 and A-7 can be reacted with aldehydes or ketones in a
reductive amination reaction to give A-5 (method B) and A-8 (method
E). Alternatively, an alkylation or addition reaction can be
performed with A-4 and A-7 to obtain intermediates A-5 and A-8.
[0293] Intermediate A-5 can be reduced with DIBAL or another
reducing reagent and will than also yield intermediates A-8 (method
C). Alternatively, intermediate A-5 can be reacted with
metallorganic reagents like GRIGNARD reagents etc. to yield
intermediates A-8.
[0294] The nitro group in intermediate A-8 (scheme 2) can be
reduced to the primary amine by reduction with indium metal and
hydrochloric acid or an alternative reduction method like
hydrogenation under RANEY nickel catalysis or others, to get to
intermediates with the structure A-9. Alternatively, intermediates
A-9 can also be obtained by oxidation of the hydoxy group in A-S,
e.g. with IBX or an alternative oxidizing reagent, to the
corresponding carbonyl compound A-10 which can be further reacted
with nucleophiles, especially organometallic reagents like GRIGNARD
or organo-zinc reagents to intermediate A-11. Intermediate A-11 can
be reacted/reduced to A-9 analogous to the transformation from A-8
to A-9.
[0295] Intermediate A-9 (scheme 3) can undergo intramolecular
cyclization to compounds (I) according to the invention with
R.sup.4=hydrogen by a MITSUNOBU reaction with triphenylposphine and
DEAD or alternative methods.
[0296] Intermediate A-10 (scheme 4), alternatively, can be
subjected to a WITTIG reaction or other olefination reactions to
prepare intermediate A-12 which can be transformed to compounds (I)
according to the invention with R.sup.4=hydrogen and
R.sup.6=--CH.sub.2CO.sub.2H by a cascade reaction which is started
by the reduction of the nitro group to the primary amine by
reaction with indium metal and hydrochloric acid followed by a ring
closing Aza-MICHAEL reaction and hydrolysis of the ester to the
carboxylic acid if necessary.
[0297] Compounds (I) which are obtained from A-9 or A-12 after
intramolecular cyclization can be derivatized in optional
derivatization steps not explicitly depicted in the schemes in all
residues, especially in R.sup.4 and R.sup.6, if they carry
functional groups, that can be further modified such as e.g,
halogen atoms, amino and hydroxy groups (including cyclic amines),
carboxylic acid or ester functions, nitrils etc. to further
compounds (I) by well established organic chemical transformations
such as metal-catalyzed cross coupling reactions, acylation,
amidation, addition, reduction or (reductive) alkylation or
cleavage of protecting groups. These additional steps are not
depicted in the general schemes. Likewise, it is also possible to
include these additional steps in the synthetic routes depicted in
the general schemes, i.e. to carry out derivatization reactions
with intermediate compounds. In addition, it may also be possible
that building blocks bearing protecting groups are used, i.e.
further steps for deprotection are necessary.
##STR00029##
[0298] In a further approach the nitro group of intermediate A-7
can be reduced analogous to the transformation from A-8 to A-9 to
generate intermediate A-13 which can be subjected to an
intramolecular MITSUNOBU reaction to generate cyclic diamine
intermediate A-14.
[0299] Intermediate A-14 can be Boc-protected to give intermediate
A-16 which can be reacted with aldehydes in a reductive amination
reaction to give Boc-protected compounds (I). Alternatively, A-16
can undergo an alkylation or addition reaction to obtain
Boc-protected (I). The Boc-protecting group can be removed by TFA
or another method to the free amine compounds (I) with
R.sup.1=hydrogen.
[0300] Alternatively, intermediate A-14 can be reacted with
aldehydes in a reductive amination reaction or other reagents to
achieve selective alkylation, addition, acylation or sulfonylation
reactions to generate intermediate A-15 which can be further
modified by an additional reaction like a reductive amination,
alkylation, addition, acylation or sulfonylation to get to
compounds (I) according to the invention. The sequence from
intermediate A-14 via intermediate A-15 to compounds (I) may also
be done in a sequential one-pot procedure.
[0301] Here once again compounds (I) which are obtained from A-15
or A-16 can be derivatized in optional derivatization steps not
explicitly depicted in the schemes in all residues, especially in
R.sup.4 and R.sup.6, if they carry functional groups, that can be
further modified such as e.g, halogen atoms, amino and hydroxy
groups (including cyclic amines), carboxylic acid or ester
functions, nitrils etc. to further compounds (I) by well
established organic chemical transformations such as
metal-catalyzed cross coupling reactions, acylation, amidation,
addition, reduction or (reductive) alkylation or cleavage of
protecting groups. Likewise, it is also possible to include these
additional steps in the synthetic routes, i.e. to carry out
derivatization reactions with intermediate compounds. In addition,
it may also be possible that building blocks bearing protecting
groups are used, i.e. further steps for deprotection are
necessary.
[0302] Compounds (I) have been tested for their activity to affect
MDM2-p53 interaction in their racemic form or alternatively as the
enantiopure form. Each of the two enantiomers of a racemic mixture
may have activity against MDM2 although with a different binding
mode. Enantiopure compounds are marked with the label "Chiral".
Compounds listed in any table below that are labeled "Chiral" (both
intermediates and compounds according to the invention) are
separated by SFC chromatography from their enantiomer or are
synthesized from enantiopure starting material which is separated
by SFC.
EXAMPLE
##STR00030##
[0304] Structure A defines the racemic mixture of compounds with
structure B and C, i.e. structure A encompasses two structures
(compounds B and C), whereas structures B and C, respectively, are
enantiopure and only define one specific compound. Thus, formulae
(I) and (Ia)
##STR00031##
with a set of specific definitions for groups R.sup.1 to R.sup.7,
V, W, X, Y, n and q represent the racemic mixture of two
enantiomers (.fwdarw.(1); structure A above is one specific example
of such a racemic mixture) or a single enantiomer (.fwdarw.(Ia);
structure B above is one specific enantiomer). The same definition
applies to synthetic intermediates.

[0393] The following Examples describe the biological activity of
the compounds according to the invention, without restricting the
invention to these Examples.
[0394] Compounds of formulae (I), (Ia) and (Ib) are characterised
by their many possible applications in the therapeutic field.
Particular mention should be made of those applications in which
the inhibiting effect on the proliferation of cultivated human
tumour cells but also on the proliferation of other cells such as
endothelial cells, for example, are involved.
[0395] Mdm2-D53 Inhibition AlphaScreen
[0396] This assay is used to determine whether the compounds
inhibit the p53-MDM2 interaction and thus restore p53 function.
[0397] 15 .mu.L of compound in 20% DMSO (serial pre-dilutions of
compound are done in 100% DMSO) is pipetted to the wells of a white
OptiPlate-96 (PerkinElmer). A mix consisting of 20 nM GST-MDM2
protein (aa 23-117) and 20 nM biotinylated p53 wt peptide
(encompassing aa 16-27 of wt human p53, amino acid sequence
QETFSDLWKLLP-Ttds-Lys-Biotin, molecular weight 2132.56 g/mol) is
prepared in assay buffer (50 mM Tris/HCl pH 7.2; 120 mM NaCl; 0.1%
bovine serum albumin (BSA); 5 mM dithiothreitol (DTT); 1 mM
ethylenediaminetetraacetic acid (EDTA); 0.01% Tween 20). 30 .mu.L
of the mix is added to the compound dilutions and incubated for 15
min at rt while gently shaking the plate at 300 rounds per minute
(rpm). Subsequently, 15 .mu.L of premixed AlphaLISA Glutathione
Acceptor Beads and AlphaScreen Streptavidin Donor Beads from
PerkinElmer (in assay buffer at a concentration of 10 .mu.g/mL
each) are added and the samples are incubated for 30 min at rt in
the dark (shaking 300 rpm). Afterwards, the signal is measured in a
PerkinElmer Envision HTS Multilabel Reader using the AlphaScreen
protocol from PerkinElmer.
[0398] Each plate contains negative controls where biotinylated
p53-peptide and GST-MDM2 are left out and replaced by assay buffer.
Negative control values are entered as low basis value when using
the software GraphPad Prism for calculations. Furthermore, a
positive control (5% DMSO instead of test compound; with
protein/peptide mix) is pipetted. Determination of IC.sub.50 values
are carried out using GraphPad Prism 3.03 software (or updates
thereof).
[0399] Table 24 shows the IC.sub.50 values of example compounds

[0400] Cell Proliferation Assays
[0401] Cell Titer Glo assay for e.g. SJSA-1, SKOV-3, RS4-11 and
KG-1 cells:
[0402] SJSA-1 cells (Osteosarcoma, wildtype p53, ATCC CRL-2098TM)
are seeded in duplicates at day 1 in flat bottom 96 well microtiter
plates (white Packard View Plate 96 well Cat. No. 6005181) in 90
.mu.L RPMI medium, 10% fetal calf serum (FCS, from e.g. JRH
Biosciences #12103-500M, Lot.: 3N0207) at a density of 2500
cells/well. Any other luminescence compatible plate format is
possible.
[0403] Similarly, p53 mutant SKOV-3 cells (ovarian adenocarcinoma,
ATCC HTB-77.TM.) are seeded in duplicates in flat bottom 96 well
microtiter plates in 90 .mu.L McCoy medium, 10% FCS at a density of
3000 cells/well.
[0404] At day 2, 5 .mu.L dilutions of the test compounds covering a
concentration range between app. 0.6 and 50000 nM are added to the
cells. Cells are incubated for three days in a humidified,
CO.sub.2-controlled incubator at 37.degree. C.
[0405] wildtype p53 RS4-11 cells (acute lymphoblastic leukemia,
ATCC CRL-1873.TM.):
[0406] Day 1: RS4-11 cells are seeded in flat bottom 96 well
microtiter plates (white Packard View Plate 96 well Cat. No.
6005181) in 90 .mu.L RPMI medium, 10% fetal calf serum (FCS, from
e.g. JRH Biosciences #12103-500M, Lot.: 3N0207) at a density of
5000 cells/well.
[0407] Any other luminescence compatible plate format is
possible.
[0408] Day 2: 5 .mu.L dilutions of the test compounds covering a
concentration range between app. 0.3 and 25000 nM (alternative
dilution schemes are possible) are added to the cells. Cells are
incubated for three days in a humidified, CO.sub.2 controlled
incubator at 37.degree. C. The final DMSO-concentration is
0.5%.
[0409] p53 mutant KG-1 cells (acute myelogenous leukemia, ATCC
CCL-246):
[0410] Day 1: KG-1 cells harboring a p53 mutation at the exon
6/intron 6 splice donor site are seeded in flat bottom 96 well
microtiter plates (white Packard View Plate 96 well Cat. No.
6005181) in 90 .mu.L IMDM medium, 10% FCS (JRH Biosciences
#12103-500M, Lot.: 3N0207) at a density of 10000 cells/well. Any
other luminescence compatible plate format is possible.
[0411] Day 2: 5 .mu.L dilutions of the test compounds covering a
concentration range between app. 0.3 and 25000 nM (alternative
dilution schemes are possible) are added to the cells. Cells are
incubated for three days in a humidified, CO.sub.2 controlled
incubator at 37.degree. C. The final DMSO-concentration is
0.5%.
[0412] Evaluation of all Cell Titer Glo assays is done at day 5
after seeding. At day 5, 95 .mu.L of Cell Titer Glo reagent (Cell
titer Glo Luminescent Cat. No. G7571, Promega) are added to each
well and incubated for additional 10 min at rt (with agitation).
Luminescence is measured on a Wallac Victor using standard
luminescence read out. IC.sub.50 values are calculated using
standard Levenburg Marquard algorithms (GraphPad Prism).
[0413] In addition, several other cancer cell lines from diverse
tissue origins proved to be sensitive to compounds (I), (Ia) and
(Ib). Examples include NCI-H460 (lung), Molp-8 (myeloma) and MV4-11

[0422] Suitable preparations include for example tablets, pills,
capsules, suppositories, lozenges, troches, solutions--particularly
solutions for injection (s.c., i.v., i.m.) and infusion
(injectables)--elixirs, syrups, sachets, emulsions, inhalatives or
dispersible powders. The content of the pharmaceutically active
compound(s) should be in the range from 0.1 to 90 wt.-%, preferably
0.5 to 50 wt.-% of the composition as a whole, i.e. in amounts
which are sufficient to achieve the dosage range specified below.
The doses specified may, if necessary, be given several times a
day.
[0423] Suitable tablets may be obtained, for example, by mixing the
active substance(s) with known excipients, for example inert
diluents such as calcium carbonate, calcium phosphate or lactose,
disintegrants such as corn starch or alginic acid, binders such as
starch or gelatine, lubricants such as magnesium stearate or talc,
agents for delaying release, such as carboxymethyl cellulose,
cellulose acetate phthalate, or polyvinyl acetate, carriers,
adjuvants, surfactants. The tablets may also comprise several
layers.
[0424] Coated tablets may be prepared accordingly by coating cores
produced analogously to the tablets with substances normally used
for tablet coatings, for example collidone or shellac, gum arabic,
talc, titanium dioxide or sugar. To achieve delayed release or
prevent incompatibilities the core may also consist of a number of
layers. Similarly the tablet coating may consist of a number of
layers to achieve delayed release, possibly using the excipients
mentioned above for the tablets.
[0425] Syrups or elixirs containing the active substances or
combinations thereof according to the invention may additionally
contain a sweetener such as saccharine, cyclamate, glycerol or
sugar and a flavour enhancer, e.g. a flavouring such as vanillin or
orange extract. They may also contain suspension adjuvants or
thickeners such as sodium carboxymethyl cellulose, wetting agents
such as, for example, condensation products of fatty alcohols with
ethylene oxide, or preservatives such as p-hydroxybenzoates.
[0426] Solutions for injection and infusion are prepared in the
usual way, e.g. with the addition of isotonic agents, preservatives
such as p-hydroxybenzoates, or stabilisers such as alkali metal
salts of ethylenediamine tetraacetic acid, optionally using
emulsifiers and/or dispersants, whilst if water is used as the
diluent, for example, organic solvents may optionally be used as
solvating agents or dissolving aids, and transferred into injection
vials or ampoules or infusion bottles.
[0427] Capsules containing one or more active substances or
combinations of active substances may for example be prepared by
mixing the active substances with inert carriers such as lactose or
sorbitol and packing them into gelatine capsules.
[0428] Suitable suppositories may be made for example by mixing
with carriers provided for this purpose such as neutral fats or
polyethyleneglycol or the derivatives thereof.
[0429] Excipients which may be used include, for example, water,
pharmaceutically acceptable organic solvents such as paraffins
(e.g. petroleum fractions), vegetable oils (e.g. groundnut or
sesame oil), mono- or polyfunctional alcohols (e.g. ethanol or
glycerol), carriers such as e.g. natural mineral powders (e.g.
kaolins, clays, talc, chalk), synthetic mineral powders (e.g.
highly dispersed silicic acid and silicates), sugars (e.g. cane
sugar, lactose and glucose), emulsifiers (e.g. lignin, spent
sulphite liquors, methylcellulose, starch and polyvinylpyrrolidone)
and lubricants (e.g. magnesium stearate, talc, stearic acid and
sodium lauryl sulphate).
[0430] The preparations are administered by the usual methods,
preferably by oral or transdermal route, most preferably by oral
route. For oral administration the tablets may of course contain,
apart from the above-mentioned carriers, additives such as sodium
citrate, calcium carbonate and dicalcium phosphate together with
various additives such as starch, preferably potato starch,
gelatine and the like. Moreover, lubricants such as magnesium
stearate, sodium lauryl sulphate and talc may be used at the same
time for the tabletting process. In the case of aqueous suspensions
the active substances may be combined with various flavour
enhancers or colourings in addition to the excipients mentioned
above.
[0431] For parenteral use, solutions of the active substances with
suitable liquid carriers may be used.
[0432] The dosage range of the compounds of formula (I), (Ia) and
(Ib) applicable per day is usually from 1 mg to 2000 mg, preferably
from 50 to 1000 mg, more preferably from 100 to 500 mg.
[0433] The dosage for intravenous use is from 1 mg to 1000 mg per
hour, preferably between 5 mg and 500 mg per hour.
[0434] However, it may sometimes be necessary to depart from the
amounts specified, depending on the body weight, the route of
administration, the individual response to the drug, the nature of
its formulation and the time or interval over which the drug is
administered. Thus, in some cases it may be sufficient to use less
than the minimum dose given above, whereas in other cases the upper
limit may have to be exceeded. When administering large amounts it
may be advisable to divide them up into a number of smaller doses
spread over the day.
[0435] The formulation examples which follow illustrate the present
invention without restricting its scope:
Examples of Pharmaceutical Formulations
TABLE-US-00035 [0436] A) Tablets per tablet active substance
according to formulae (I) or (Ia) or (Ib) 100 mg lactose 140 mg
corn starch 240 mg polyvinylpyrrolidone 15 mg magnesium stearate 5
mg 500 mg
[0437] The finely ground active substance, lactose and some of the
corn starch are mixed together. The mixture is screened, then
moistened with a solution of polyvinylpyrrolidone in water,
kneaded, wet-granulated and dried. The granules, the remaining corn
starch and the magnesium stearate are screened and mixed together.
The mixture is compressed to produce tablets of suitable shape and
size.
TABLE-US-00036 B) Tablets per tablet active substance according to
formulae (I) or (Ia) or (Ib) 80 mg lactose 55 mg corn starch 190 mg
microcrystalline cellulose 35 mg polyvinylpyrrolidone 15 mg
sodiumcarboxymethyl starch 23 mg magnesium stearate 2 mg 400 mg
[0438] The finely ground active substance, some of the corn starch,
lactose, microcrystalline cellulose and polyvinylpyrrolidone are
mixed together, the mixture is screened and worked with the
remaining corn starch and water to form a granulate which is dried
and screened. The sodiumcarboxymethyl starch and the magnesium
stearate are added and mixed in and the mixture is compressed to
form tablets of a suitable size.
TABLE-US-00037 C) Ampoule solution active substance according to
formulae (I) or (Ia) 50 mg sodium chloride 50 mg water for inj. 5
mL
[0439] The active substance is dissolved in water at its own pH or
optionally at pH 5.5 to 6.5 and sodium chloride is added to make it
isotonic. The solution obtained is filtered free from pyrogens and
the filtrate is transferred under aseptic conditions into ampoules
which are then sterilised and sealed by fusion. The ampoules
contain 5 mg, 25 mg and 50 mg of active substance.
