Description
REFERENCE TO RELATED APPLICATION
[0001] This Application claims the benefit of U.S. Provisional
Application Serial No. 60/417,371 filed October 9, 2002.
FIELD OF THE INVENTION
[0002] The present invention relates to novel substituted
thiadiazoledioxide and thiadiazolemonooxide compounds,
pharmaceutical compositions containing the compounds, and the use
of the compounds and formulations in treating CXC and
CC-chemokine-mediated diseases.
BACKGROUND OF THE INVENTION
[0003] Chemokines are chemotactic cytokines that are released by a
wide variety of cells to attract macrophages, T-cells, eosinophils,
basophils, neutrophils and endothelial cells to sites of
inflammation and tumor growth. There are two main classes of
chemokines, the CXC-chemokines and the CC-chemokines. The class
depends on whether the first two cysteines are separated by a
single amino acid (CXC-chemokines) or are adjacent (CC-chemokines).
The CXC-chemokines include, but are not limited to, interleukin-8
(IL-8), neutrophil-activating protein-1 (NAP-1),
neutrophil-activating protein-2 (NAP-2), GRO.alpha., GRO.beta.,
GRO.gamma., ENA-78, GCP-2, IP-10, MIG and PF4. CC chemokines
include, but are not limited to, RANTES, MIP-1.alpha., MIP-2.beta.,
monocyte chemotactic protein-1 (MCP-1), MCP-2, MCP-3, CCL19, CCL21
and eotaxin. Individual members of the chemokine families are known
to be bound by at least one chemokine receptor, with CXC-chemokines
generally bound by members of the CXCR class of receptors, and
CC-chemokines by members of the CCR class of receptors. For
example, IL-8 is bound by the CXCR-1 and CXCR-2 receptors.
[0004] Since CXC-chemokines promote the accumulation and activation
of neutrophils, these chemokines have been implicated in a wide
range of acute and chronic inflammatory disorders including
psoriasis and rheumatoid arthritis. Baggiolini et al., FEBS Lett.
307, 97 (1992); Miller et al., Crit. Rev. Immunol. 12, 17 (1992);
Oppenheim et al., Annu. Fev. Immunol. 9, 617 (1991); Seitz et al.,
J. Clin. Invest. 87, 463 (1991); Miller et al., Am. Rev. Respir.
Dis. 146, 427 (1992); Donnely et al., Lancet 341, 643(1993).
[0005] ELRCXC chemokines including IL-8, GRO.alpha., GRO.beta.,
GRO.gamma., NAP-2, and ENA-78 (Strieter et al. 1995 JBC 270 p.
27348-57) have also been implicated in the induction of tumor
angiogenesis (new blood vessel growth). All of these chemokines are
believed to exert their actions by binding to the 7 transmembrane
G-protein coupled receptor CXCR2 (also known as IL-8RB), while IL-8
also binds CXCR1 (also known as IL-8RA). Thus, their angiogenic
activity is due to their binding to and activation of CXCR2, and
possible CXCR1 for IL-8, expressed on the surface of vascular
endothelial cells (ECs) in surrounding vessels.
[0006] Many different types of tumors have been shown to produce
ELRCXC chemokines and their production has been correlated with a
more aggressive phenotype (Inoue et al. 2000 Clin Cancer Res 6 p.
2104-2119) and poor prognosis (Yoneda et. al. 1998 J Nat Cancer
Inst 90 p. 447-454). Chemokines are potent chemotactic factors and
the ELRCXC chemokines have been shown to induce EC chemotaxis.
Thus, these chemokines probably induce chemotaxis of endothelial
cells toward their site of production in the tumor. This may be a
critical step in the induction of angiogenesis by the tumor.
Inhibitors of CXCR2 or dual inhibitors of CXCR2 and CXCR1 will
inhibit the angiogenic activity of the ELRCXC chemokines and
therefore block the growth of the tumor. This anti-tumor activity
has been demonstrated for antibodies to IL-8 (Arenberg et al. 1996
J Clin Invest 97 p. 2792-2802), ENA-78 (Arenberg et al. 1998 J Clin
Invest 102 p.465-72), and GRO.alpha. (Haghnegahdar et al. J. Leukoc
Biology 2000 67 p. 53-62).
[0007] Many tumor cells have also been shown to express CXCR2 and
thus tumor cells may also stimulate their own growth when they
secrete ELRCXC chemokines. Thus, along with decreasing
angiogenesis, inhibitors of CXCR2 may directly inhibit the growth
of tumor cells.
[0008] Hence, the CXC-chemokine receptors represent promising
targets for the development of novel anti-inflammatory and
anti-tumor agents.
[0009] There remains a need for compounds that are capable of
modulating activity at CXC-chemokine receptors. For example,
conditions associated with an increase in IL-8 production (which is
responsible for chemotaxis of neutrophil and T-cell subsets into
the inflammatory site and growth of tumors) would benefit by
compounds that are inhibitors of IL-8 receptor binding.

[0506] Representative compounds of the invention include but are
not limited to:

[0507] the pharmaceutically acceptable salts thereof, and the
pharmaceutically acceptable solvates thereof.
[0508] Preferred compounds of this invention are selected from the
group consisting of: 176177178179180181182183184185186187188189
[0509] the pharmaceutically acceptable salts thereof, and the
pharmaceutically acceptable
[0510] More preferred compounds of this invention are selected from
the group consisting of: 190191192193194195196197198199200
[0511] the pharmaceutically acceptable salts thereof, and the
pharmaceutically acceptable solvates thereof.
[0512] Most preferred compounds of this invention are selected from
the group consisting of: 201202203204205206207208209210211
[0513] the pharmaceutically acceptable salts, and the
pharmaceutically acceptable solvates thereof.
[0514] An embodiment of this invention is directed to compounds of
formula IA selected from the group consisting of compounds of the
formula: 212213214215216217218
[0515] the pharmaceutically acceptable salts thereof, and the
pharmaceutically acceptable solvates thereof.
[0516] Certain compounds of the invention may exist in different
stereoisomeric forms (e.g., enantiomers, diastereoisomers and
atropisomers). The invention contemplates all such stereoisomers
both in pure form and in admixture, including racemic mixtures.
Isomers can be prepared using conventional methods.
[0517] Certain compounds will be acidic in nature, e.g. those
compounds which possess a carboxyl or phenolic hydroxyl group.
These compounds may form pharmaceutically acceptable salts.
Examples of such salts may include sodium, potassium, calcium,
aluminum, gold and silver salts. Also contemplated are salts formed
with pharmaceutically acceptable amines such as ammonia, alkyl
amines, hydroxyalkylamines, N-methylglucamine and the like.
[0518] Certain basic compounds also form pharmaceutically
acceptable salts, e.g., acid addition salts. For example, the
pyrido-nitrogen atoms may form salts with strong acid, while
compounds having basic substituents such as amino groups also form
salts with weaker acids. Examples of suitable acids for salt
formation are hydrochloric, sulfuric, phosphoric, acetic, citric,
oxalic, malonic, salicylic, malic, fumaric, succinic, ascorbic,
maleic, methanesulfonic and other mineral and carboxylic acids well
known to those skilled in the art. The salts are prepared by
contacting the free base form with a sufficient amount of the
desired acid to produce a salt in the conventional manner. The free
base forms may be regenerated by treating the salt with a suitable
dilute aqueous base solution such as dilute aqueous NaOH, potassium
carbonate, ammonia and sodium bicarbonate. The free base forms
differ from their respective salt forms somewhat in certain
physical properties, such as solubility in polar solvents, but the
acid and base salts are otherwise equivalent to their respective
free base forms for purposes of the invention.
[0519] All such acid and base salts are intended to be
pharmaceutically acceptable salts within the scope of the invention
and all acid and base salts are considered equivalent to the free
forms of the corresponding compounds for purposes of the
invention.
[0520] Compounds of formula IA can exist in unsolvated and solvated
forms, including hydrated forms. In general, the solvated forms,
with pharmaceutically acceptable solvents such as water, ethanol
and the like, are equivalent to the unsolvated forms for the
purposes of this invention.
[0521] This invention also includes Prodrugs of the novel compounds
of this invention. The term "prodrug," as used herein, represents
compounds which are rapidly transformed in vivo to the parent
compound of the above formula, for example, by hydrolysis in blood.
A thorough discussion is provided in T. Higuchi and V. Stella,
Pro-drugs as Novel Delivery Systems, Vol. 14 of the A.C.S.
Symposium Series, and in Edward B. Roche, ed., Bioreversible
Carriers in Drug Design, American Pharmaceutical Association and
Pergamon Press, 1987, both of which are incorporated herein by
reference.
[0522] This invention also includes the compounds of this invention
in isolated and pure form.
[0523] For preparing pharmaceutical compositions from the compounds
described by this invention, inert, pharmaceutically acceptable
carriers can be either solid or liquid. Solid form preparations
include powders, tablets, dispersible granules, capsules, cachets
and suppositories. The powders and tablets may be comprised of from
about 5 to about 95 percent active ingredient. Suitable solid
carriers are known in the art, e.g., magnesium carbonate, magnesium
stearate, talc, sugar or lactose. Tablets, powders, cachets and
capsules can be used as solid dosage forms suitable for oral
administration. Examples of pharmaceutically acceptable carriers
and methods of manufacture for various compositions may be found in
A. Gennaro (ed.), Remington: is The Science and Practice of
Pharmacy, 20.sup.th Edition, (2000), Lippincott Williams &
Wilkins, Baltimore, Md.
[0524] Liquid form preparations include solutions, suspensions and
emulsions. As an example may be mentioned water or water-propylene
glycol solutions for parenteral injection or addition of sweeteners
and opacifiers for oral solutions, suspensions and emulsions.
Liquid form preparations may also include solutions for intranasal
administration.
[0525] Aerosol preparations suitable for inhalation may include
solutions and solids in powder form, which may be in combination
with a pharmaceutically acceptable carrier, such as an inert
compressed gas, e.g. nitrogen.
[0526] Also included are solid form preparations that are intended
to be converted, shortly before use, to liquid form preparations
for either oral or parenteral administration. Such liquid forms
include solutions, suspensions and emulsions.
[0527] The compounds of the invention may also be deliverable
transdermally. The transdermal composition can take the form of
creams, lotions, aerosols and/or emulsions and can be included in a
transdermal patch of the matrix or reservoir type as are
conventional in the art for this purpose.
[0528] Preferably the compound is administered orally.
[0529] Preferably, the pharmaceutical preparation is in a unit
dosage form. In such form, the preparation is subdivided into
suitably sized unit doses containing appropriate quantities of the
active component, e.g., an effective amount to achieve the desired
purpose.
[0530] The quantity of active compound in a unit dose of
preparation may be varied or adjusted from about 0.01 mg to about
1000 mg, preferably from about 0.01 mg to about 750 mg, more
preferably from about 0.01 mg to about 500 mg, and most preferably
from about 0.01 mg to about 250 mg, according to the particular
application.
[0531] The actual dosage employed may be varied depending upon the
requirements of the patient and the severity of the condition being
treated. Determination of the proper dosage regimen for a
particular situation is within the skill of the art. For
convenience, the total dosage may be divided and administered in
portions during the day as required.
[0532] The amount and frequency of administration of the compounds
of the invention and/or the pharmaceutically acceptable salts
thereof will be regulated according to the judgment of the
attending clinician considering such factors as age, condition and
size of the patient as well as severity of the symptoms being
treated. A typical recommended daily dosage regimen for oral
administration can range from about 0.04 mg/day to about 4000
mg/day, in two to four divided doses.
[0533] Classes of compounds that can be used as the
chemotherapeutic agent (antineoplastic agent) include: alkylating
agents, antimetabolites, natural products and their derivatives,

[0539] Methods for the safe and effective administration of most of
these chemotherapeutic agents are known to those skilled in the
art. In addition, their administration is described in the standard
literature. For example, the administration of many of the
chemotherapeutic agents is described in the "Physicians' Desk
Reference" (PDR), e.g., 2002 edition (Medical Economics Company,
Montvale, N.J. 07645-1742, USA); the disclosure of which is
incorporated herein by reference thereto.
[0540] As used herein, a microtubule affecting agent is a compound
that interferes with cellular mitosis, i.e., having an anti-mitotic
effect, by affecting microtubule formation and/or action. Such
agents can be, for instance, microtubule stabilizing agents or
agents that disrupt microtubule formation.
[0541] Microtubule affecting agents useful in the invention are
well known to those of skill in the art and include, but are not
limited to allocolchicine (NSC 406042), Halichondrin B (NSC
609395), colchicine (NSC 757), colchicine derivatives (e.g., NSC
33410), dolastatin 10 (NSC 376128), maytansine (NSC 153858),
rhizoxin (NSC 332598), paclitaxel (Taxol.RTM., NSC 125973),
Taxol.RTM. derivatives (e.g., derivatives (e.g., NSC 608832),
thiocolchicine (NSC 361792), trityl cysteine (NSC 83265),
vinblastine sulfate (NSC 49842), vincristine sulfate (NSC 67574),
epothilone A, epothilone, and discodermolide (see Service, (1996)
Science, 274:2009) estramustine, nocodazole, MAP4, and the like.
Examples of such agents are also described in the scientific and
patent literature, see, e.g., Bulinski (1997) J. Cell Sci.
110:3055-3064; Panda (1997) Proc. Natl. Acad. Sci. USA
94:10560-10564; Muhlradt (1997) Cancer Res. 57:3344-3346; Nicolaou
(1997) Nature 387:268-272; Vasquez (1997) Mol. Biol. Cell.
8:973-985; Panda (1996) J. Biol. Chem. 271:29807-29812.
[0542] Particularly preferred agents are compounds with
paclitaxel-like activity. These include, but are not limited to
paclitaxel and paclitaxel derivatives (paclitaxel-like compounds)
and analogues. Paclitaxel and its derivatives are available
commercially. In addition, methods of making paclitaxel and
paclitaxel derivatives and analogues are well known to those of
skill in the art (see, e.g., U.S. Patent Nos: 5,569,729; 5,565,478;
5,530,020; 5,527,924; 5,508,447; 5,489,589; 5,488,116; 5,484,809;
5,478,854; 5,478,736; 5,475,120; 5,468,769; 5,461,169; 5,440,057;
5,422,364; 5,411,984; 5,405,972; and 5,296,506).
[0543] More specifically, the term "paclitaxel" as used herein
refers to the drug commercially available as Taxol.RTM.(NSC number:
125973). Taxol.RTM. inhibits eukaryotic cell replication by
enhancing polymerization of tubulin moieties into stabilized
microtubule bundles that are unable to reorganize into the proper
structures for mitosis. Of the many available chemotherapeutic
drugs, paclitaxel has generated interest because of its efficacy in
clinical trials against drug-refractory tumors, including ovarian
and mammary gland tumors (Hawkins (1992) Oncology, 6: 17-23,
Horwitz (1992) Trends Pharmacol. Sci. 13: 134-146, Rowinsky (1990)
J. Natl. Canc. Inst. 82: 1247-1259).
[0544] Additional microtubule affecting agents can be assessed
using one of many such assays known in the art, e.g., a
semiautomated assay which measures the tubulin-polymerizing
activity of paclitaxel analogs in combination with a cellular assay
to measure the potential of these compounds to block cells in
mitosis (see Lopes (1997) Cancer Chemother. Pharmacol.
41:37-47).
[0545] Generally, activity of a test compound is determined by
contacting a cell with that compound and determining whether or not
the cell cycle is disrupted, in particular, through the inhibition
of a mitotic event. Such inhibition may be mediated by disruption
of the mitotic apparatus, e.g., disruption of normal spindle
formation. Cells in which mitosis is interrupted may be
characterized by altered morphology (e.g., microtubule compaction,
increased chromosome number, etc.).
[0546] Compounds with possible tubulin polymerization activity can
be screened in vitro. In a preferred embodiment, the compounds are
screened against cultured WR21 cells (derived from line 69-2
wap-ras mice) for inhibition of proliferation and/or for altered
cellular morphology, in particular for microtubule compaction. In
vivo screening of positive-testing compounds can then be performed
using nude mice bearing the WR21 tumor cells. Detailed protocols
for this screening method are described by Porter (1995) Lab. Anim.
Sci., 45(2):145-150.
[0547] Other methods of screening compounds for desired activity
are well known to those of skill in the art. Typically such assays
involve assays for inhibition of microtubule assembly and/or
disassembly. Assays for microtubule assembly are described, for
example, by Gaskin et al. (1974) J. Molec. Biol., 89: 737-758. U.S.
Pat. No. 5,569,720 also provides in vitro and in vivo assays for
compounds with paclitaxel-like activity.
[0548] Methods for the safe and effective administration of the
above-mentioned microtubule affecting agents are known to those
skilled in the art. In addition, their administration is described
in the standard literature. For example, the administration of many
of the chemotherapeutic agents is described in the "Physicians'
Desk Reference" (PDR), e.g., 1996 edition (Medical Economics
Company, Montvale, N.J. 07645-1742, USA); the disclosure of which
is incorporated herein by reference thereto.
[0549] The amount and frequency of administration of the compounds
of formula IA and the chemotherapeutic agents and/or radiation
therapy will be regulated according to the judgment of the
attending clinician (physician) considering such factors as age,
condition and size of the patient as well as severity of the
disease being treated. A dosage regimen of the compound of formula
IA can be oral administration of from 10 mg to 2000 mg/day,
preferably 10 to 1000 mg/day, more preferably 50 to 600 mg/day, in
two to four (preferably two) divided doses, to block tumor growth.
Intermittant therapy (e.g., one week out of three weeks or three
out of four weeks) may also be used.
[0550] The chemotherapeutic agent and/or radiation therapy can be
administered according to therapeutic protocols well known in the
art. It will be apparent to those skilled in the art that the
administration of the chemotherapeutic agent and/or radiation
therapy can be varied depending on the disease being treated and
the known effects of the chemotherapeutic agent and/or radiation
therapy on that disease. Also, in accordance with the knowledge of
the skilled clinician, the therapeutic protocols (e.g., dosage
amounts and times of administration) can be varied in view of the
observed effects of the administered therapeutic agents (i.e.,
antineoplastic agent or radiation) on the patient, and in view of
the observed responses of the disease to the administered
therapeutic agents.
[0551] In the methods of this invention, a compound of formula IA
is administered concurrently or sequentially with a
chemotherapeutic agent and/or radiation. Thus, it is not necessary
that, for example, the chemotherapeutic agent and the compound of
formula IA, or the radiation and the compound of formula IA, should
be administered simultaneously or essentially simultaneously. The
advantage of a simultaneous or essentially simultaneous
administration is well within the determination of the skilled
clinician.
[0552] Also, in general, the compound of formula IA and the
chemotherapeutic agent do not have to be administered in the same
pharmaceutical composition, and may, because of different physical
and chemical characteristics, have to be administered by different
routes. For example, the compound of formula IA may be administered
orally to generate and maintain good blood levels thereof, while
the chemotherapeutic agent may be administered intravenously. The
determination of the mode of administration and the advisability of
administration, where possible, in the same pharmaceutical
composition, is well within the knowledge of the skilled clinician.
The initial administration can be made according to established
protocols known in the art, and then, based upon the observed
effects, the dosage, modes of administration and times of
administration can be modified by the skilled clinician.
[0553] The particular choice of a compound of formula IA, and
chemotherapeutic agent and/or radiation will depend upon the
diagnosis of the attending physicians and their judgement of the
condition of the patient and the appropriate treatment
protocol.
[0554] The compound of formula IA, and chemotherapeutic agent
and/or radiation may be administered concurrently (e.g.,
simultaneously, essentially simultaneously or within the same
treatment protocol) or sequentially, depending upon the nature of
the proliferative disease, the condition of the patient, and the
actual choice of chemotherapeutic agent and/or radiation to be
administered in conjunction (i.e., within a single treatment
protocol) with the compound of formula or IA.
[0555] If the compound of formula IA, and the chemotherapeutic
agent and/or radiation are not administered simultaneously or
essentially simultaneously, then the initial order of
administration of the compound of formula IA, and the
chemotherapeutic agent and/or radiation, may not be important.
Thus, the compound of formula IA may be administered first,
followed by the administration of the chemotherapeutic agent and/or
radiation; or the chemo-therapeutic agent and/or radiation may be
administered first, followed by the administration of the compound
of formula IA. This alternate administration may be repeated during
a single treatment protocol. The determination of the order of
administration, and the number of repetitions of administration of
each therapeutic agent during a treatment protocol, is well within
the knowledge of the skilled physician after evaluation of the
disease being treated and the condition of the patient.
[0556] For example, the chemotherapeutic agent and/or radiation may
be administered first, especially if it is a cytotoxic agent, and
then the treatment continued with the administration of the
compound of formula IA followed, where determined advantageous, by
the administration of the chemotherapeutic agent and/or radiation,
and so on until the treatment protocol is complete.
[0557] Thus, in accordance with experience and knowledge, the
practicing physician can modify each protocol for the
administration of a component (therapeutic agent--i.e., the
compound of formula IA, chemotherapeutic agent or radiation) of the
treatment according to the individual patient's needs, as the
treatment proceeds.
[0558] The attending clinician, in judging whether treatment is
effective at the dosage administered, will consider the general
well-being of the patient as well as more definite signs such as
relief of disease-related symptoms, inhibition of tumor growth,
actual shrinkage of the tumor, or inhibition of metastasis. Size of
the tumor can be measured by standard methods such as radio-logical
studies, e.g., CAT or MRI scan, and successive measurements can be
used to judge whether or not growth of the tumor has been retarded
or even reversed. Relief of disease-related symptoms such as pain,
and improvement in overall condition can also be used to help judge
effectiveness of treatment.
BIOLOGICAL EXAMPLES
[0559] The compounds of the present invention are useful in the
treatment of CXC-chemokine mediated conditions and diseases. This
utility is manifested in their ability to inhibit IL-8 and
GRO-.alpha. chemokine as demonstrated by the following in vitro
assays.
[0560] Receptor Binding Assays:
[0561] CXCR1 SPA Assay
[0562] For each well of a 96 well plate, a reaction mixture of 10
.mu.g hCXCR1-CHO overexpressing membranes (Biosignal) and 200
.mu.g/well WGA-SPA beads (Amersham) in 100 .mu.l was prepared in
CXCR1 assay buffer (25 mM HEPES, pH 7.8, 2 mM CaCl.sub.2, 1 mM
MgCl.sub.2, 125 mM NaCl, 0.1% BSA) (Sigma). A 0.4 nM stock of
ligand, [125I]-IL-8 (NEN) was prepared in the CXCR1 assay buffer.
20.times. stock solutions of test compounds were prepared in DMSO
(Sigma). A 6.times. stock solution of IL-8 (R&D) was prepared
in CXCR2 assay buffer. The above solutions were added to a 96-well
assay plate (PerkinElmer) as follows: 10 .mu.l test compound or
DMSO, 40 .mu.l CXCR1 assay buffer or IL-8 stock, 100 .mu.l of
reaction mixture, 50 .mu.l of ligand stock (Final [Ligand]=0.1 nM).
The assay plates were shaken for 5 minutes on plate shaker, then
incubated for 8 hours before cpm/well were determined in Microbeta
Trilux counter (PerkinElmer). % Inhibition of Total binding-NSB
(250 nM IL-8) was determined for IC.sub.50 values.
[0563] Alternative CXCR1 SPA Assay
[0564] Protocol using CXCR1-Expressing Membranes from Biosiqnal
Packard
[0565] For each 50 .mu.l reaction, a working stock of 0.25
.mu.g/.mu.l hCXCR1-CHO over-expressing membranes with a specific
activity of 0.05 pmol/mg (Biosignal Packard) and 25 .mu.g/.mu.l
WGA-SPA beads (Perkin Elmer Life Sciences) was prepared in CXCR1
assay buffer (25 mM HEPES, pH 7.8, 0.1 mM CaCl.sub.2, 1 mM
MgCl.sub.2, 100 mM NaCl) (Sigma). This mixture was incubated on ice
for 30 minutes and then centrifuged at 2500 rpm for 5 minutes. The
beads and membranes were resuspended in CXCR1 assay buffer to the
same concentrations as in the original mixture. A 0.125 nM stock of
ligand, [.sup.125I]-IL-8 (Perkin Elmer Life Sciences), was prepared
in the CXCR1 assay buffer. Test compounds were first serially
diluted by half-logs in DMSO (Sigma) and then diluted 20-fold in
CXCR1 assay buffer. The above solutions were added to a Corning NBS

[0579] Calcium Fluorescence Assay (FLIPR)
[0580] HEK 293 cells stably transfected with hCXCR2 and G.alpha./q
were plated at 10,000 cells per well in a Poly-D-Lysine Black/Clear
plate (Becton Dickinson) and incubated 48 hours at 5% CO.sub.2,
37.degree. C. The cultures were then incubated with 4 mM fluo-4, AM
(Molecular Probes) in Dye Loading Buffer (1 % FBS, HBSS w. Ca &
Mg, 20 mM HEPES (Cellgro), 2.5 mM Probenicid (Sigma) for 1 hour.
The cultures were washed with wash buffer (HBSS w Ca, & Mg, 20
mM HEPES, Probenicid (2.5 mM)) three times, then 100 .mu.l/well
wash buffer was added.
[0581] During incubation, compounds were prepared as 4.times.
stocks in 0.4% DMSO (Sigma) and wash buffer and added to their
respective wells in the first addition plate. IL-8 or GRO-.alpha.
(R&D Systems) concentrations were prepared 4.times. in wash
buffer+0.1 % BSA and added to their respective wells in second
addition plate.
[0582] Culture plate and both addition plates were then placed in
the FLIPR imaging system to determine change in calcium
fluorescence upon addition of compound and then ligand. Briefly, 50
.mu.l of compound solutions or DMSO solution was added to
respective wells and change in calcium fluorescence measured by the
FLIPR for 1 minute. After a 3 minute incubation within the

[0583] Chemotaxis Assays for 293-CXCR2
[0584] A chemotaxis assay is setup using Fluorblok inserts (Falcon)
for 293-CXCR2 cells (HEK-293 cells overexpressing human CXCR2). The
standard protocol used at present is as follows:
[0585] 1. Inserts are coated with collagenIV (2 ug/ml) for 2 hrs at
37.degree. C.
[0586] 2. The collagen is removed and inserts are allowed to air
dry overnight.
[0587] 3. Cells are labeled with 10 uM calcein AM (Molecular
Probes) for 2 hrs. Labeling is done in complete media with 2%
FBS.
[0588] 4. Dilutions of compound are made in minimal media (0.1%
BSA) and placed inside the insert which is positioned inside the
well of a 24 well plate. Within the well is IL-8 at a concentration
of 0.25 nM in minimal media. Cells are washed and resuspended in
minimal media and placed inside the insert at a concentration of
50,000 cells per insert.
[0589] 5. Plate is incubated for 2 hrs and inserts are removed and
placed in a new 24 well. Fluorescence is detected at excitation=485
nM and emission=530 nM.
[0590] Cytotoxicity Assays
[0591] A cytotoxicity assay for CXCR2 compounds is conducted on
293-CXCR2 cells. Concentrations of compounds are tested for
toxicity at high concentrations to determine if they may be used
for further evaluation in binding and cell based assays. The
protocol is as follows:
[0592] 1. 293-CXCR2 cells are plated overnight at a concentration
of 5000 cells per well in complete media.
[0593] 2. Dilutions of compound are made in minimal media w/0.1%
BSA. Complete media is poured off and the dilutions of compound are
added. Plates are incubated for 4, 24 and 48 hrs. Cells are labeled
with 10 uM calcein AM for 15 minutes to determine cell viability.
Detection method is the same as above.
[0594] Soft Agar Assay
[0595] 10,000 SKMEL-5 cells/well are placed in a mixture of 1.2%
agar and complete media with various dilutions of compound. Final
concentration of agar is 0.6%. After 21 days viable cell colonies
are stained with a solution of MTT (1 mg/ml in PBS). Plates are
then scanned to determine colony number and size. IC.sub.50 is
determined by comparing total area vs. compound concentration.
[0596] CCR7 Membrane Preparation.
[0597] Ba/F3-CCR7 membranes were prepared as previously described
(Hipkin et al., J. Biol. Chem., 272, 1997, 13869-76). Cells were
pelleted by centrifugation, incubated in homogenization buffer (10
mM Tris-HCl, 5 mM EDTA, 3 mM EGTA, pH 7.6) and 1 .mu.M PMSF for 30
min. on ice. The cells were then lysed with a Dounce homogenizer
using stirrer type RZR3 polytron homogenizer (Caframo, Wiarton,
Ont.) with 12 strokes at 900 RPM. The intact cells and nuclei were
removed by centrifugation at 500.times.g for 5 min. The cell
membranes in the supernatant were then pelleted by centrifugation
at 100,000.times.g for 30 min. The membranes were then resuspended
in glygly buffer (20 mM glycylglycine, 1 mM MgCl.sub.2, 250 mM
sucrose, pH 7.2), aliquoted, quick frozen and stored at -80.degree.

([.sup.35S]GTP.gamma.S, triethylammonium salt; specific
activity=1250 Ci/mmol; NEN Boston, Mass.) was measured using a
scintillation proximity assay (SPA) as previously described (Cox,

(Wallac, Gaithersburg, Md.) and incubated with 10 .mu.M guanosine
5'-diphosphate (GDP) in the presence or absence of 2 nM MIP-3.beta.
and/or compounds for 60 min at room temperature. The incubation
continued for another 60 min. following the addition of 0.1 nM

[0601] Compounds of formula IA may be produced by processes known
to those skilled in the art, in the following reaction schemes, and
in the preparations and examples below.
[0602] A general procedure for the preparation of compounds of
formula IA is as follows: 219
[0603] Compounds of this invention are prepared by condensing an
amine (either A-NH.sub.2 or B--NH.sub.2) with
dimethoxythiadiazoledioxide to give the
monomethoxy-thiadiazoledioxide intermediate. Subsequent
condensation of this intermediate with the commercially available
or prepared amine (either A-NH.sub.2 or B--NH.sub.2) provides the
desired chemokine antagonist. 220
[0604] Thiadiazoleoxide compounds are prepared similarly starting
with dimethoxythiadiazoleoxide. Sequential condensation with amine
A-NH.sub.2 or B--NH.sub.2 as described above provides the desired
antagonist.

the filtrated was concentrated to a yellow oil, dried on high
vacuum, yielding 17.2 g (93%) of the desired ester.
[1076] Step B
[1077] The ester product obtained from Step A above (17.2 g, 73.18
mmol) was converted to 2-ethyl4-tertbutyl-5-bromo-furoate (7.9 g,
37%) using the literature procedure: J. Am. Chem.Soc., 1939, 61,
473478 (the disclosure of which is incorporated herein by reference
thereto).
[1078] Step C
[1079] The ester product obtained from Step B above (7.9 g, 27.13
mol) was reduced to the alcohol (6.32 g) using the procedure set
forth in Preparative Example 34.8, Step C.
[1080] Step D
[1081] The product obtained from Step C above (6.32 g) was
dissolved in 140 mL of THF and cooled in a -78.degree. C. bath. A
2.5 M solution of n-butyllithium in hexanes (22 mL, 55.0 mmol) was
added dropwise along the side wall of the flask. After 15 min,
H.sub.2O (.about.70 mL) was added. Cooling bath was removed, the
mixture was stirred for an additional 1 h. Brine (50 mL) and
CH.sub.2Cl.sub.2 (300 mL) were added, the two layers were
separated, the aqueous layer was extracted with CH.sub.2Cl.sub.2
(100 mL), and the combined organic layers ere dried by
Na.sub.2SO.sub.4. Evaporation of solvents afforded 5.33 g (crude)
of the debrominated product as a reddish brown oil.
[1082] Step E
[1083] The alcohol product obtained from Step D above (5.33 g) was
oxidized to the corresponding aldehyde (3.06 g, 74% over three
steps) using the procedure set forth in Preparative Example 34.8,
Step D.
PREPARATIVE EXAMPLE 34.18
[1084] 855
[1085] Step A
[1086] To a stirred solution of cyclopropyl bromide (4.0 mL, 50
mmol) in 120 mL of ether at -78.degree. C. was added dropwise a
1.7M solution of t-butyllithium in pentane (44.5 mL, 75.7 mmol).
After 10 min, cooling bath was removed, stirring was continued for
1.5 h. The mixture was cooled again in a -78.degree. C. bath, and
3-furaldehyde (3.5 mL, 41.9 mmol) was added. Reaction was continued
for 1 h, and quenched with a saturated NH4Cl aqueous solution. The
aqueous mixture was extracted with CH.sub.2Cl.sub.2 (100
mL.times.3). The organic extracts were washed with brine, dried by
Na.sub.2SO.sub.4, filtered, and concentrated in vacuo to give 5.3 g
(91%) of the alcohol product as a yellow oil.
[1087] Step B
[1088] Chloro trimethylsilane (27.2 mL, 214.2 mmol) was added
dropwise to a vigorously stirred suspension of sodium iodide (32 g,
213.5 mmol) in 100 mL of acetonitrile. After 5 min, a solution of
the alcohol obtained from Step A above (4.93 g, 35.68 mmol) in 100
mL of acetonitrile was added dropwise. Stirring was continued for 5
min. H.sub.2O (100 mL) was added, the layers were separated, and
the aqueous layer was extracted with ether (100 mL.times.2). The
organic layers were combined, washed with a 10%
Na.sub.2S.sub.2O.sub.3 aqueous solution and brine, and dried over
Na.sub.2SO.sub.4. Evaporation of solvents gave a dark brown oil,
which was filtered through a 5-in silica gel column, eluting with
CH.sub.2Cl.sub.2-hexanes (1:3.5, v/v). Removal of solvents afforded
4.22 g (47%) of the iodo product as a light yellow oil.
[1089] Step C
[1090] The iodo-product obtained from Step B above (2.2 g, 8.8
mmol) was dissolved in 60 mL of ether, and stirred in a -78.degree.
C. bath. A 1.7 M solution of t-butyllithium in pentane (10.4 mL,
17.7 mmol) was added dropwise. After 20 min, cooling bath was
removed. Reaction was continued for 2.5 h, and quenched with
H.sub.2O (20 mL). The aqueous mixture was stirred overnight and
separated. The aqueous layer was extracted with ether (30 mL). The
combined organic layers were washed with brine, dried by
Na.sub.2SO.sub.4, and filtered through a Celite pad. Removal of
solvent gave 1.10 g (100%) of 3-butylfuran as a reddish-yellow
oil.
[1091] Step D
[1092] 3-Butylfuran (1.1 g, 8.8 mmol), obtained from Step C above,
was dissolved in 60 mL of ether, and stirred in a -78.degree. C.
bath. A 1.7 M solution of t-butyllithium in pentane (6.0 mL, 10.2
mmol) was added dropwise along the side wall of the flask. The
mixture was stirred for 3 h from -78.degree. C. to 0.degree. C.,
and continued for 1 h at room temperature. A solution of
N,N'-dimethylforamide (1.1 mL, 14.23 mmol) was added. Reaction was
continued overnight, and quenched with a saturated NH.sub.4Cl
aqueous solution. The two layers were separated, the aqueous layer
was extracted with CH.sub.2Cl.sub.2 (30 mL.times.2). The combined
organic layers were washed with brine, dried with Na.sub.2SO.sub.4,
and concentrated to an oil, which was purified by preparative TLC
(CH.sub.2Cl.sub.2-hexanes=1:1.5, v/v) to give 0.48 g (36%) of the
aldehyde (contaminated by some 3-butyl-2-furaldehyde).

PREPARATIVE EXAMPLE 64
[1111] 955
[1112] Step A
[1113] To a solution of (D)-valinol (4.16 g, 40.3 mmol) in
CH.sub.2Cl.sub.2 (60 mL) at 0.degree. C. was added MgSO.sub.4 (20
g) followed by dropwise addition of 3-fluorobenzaldehyde (5.0 g,
40.3 mmol). The heterogenous solution was stirred at 0.degree. C.
for 2 h and was allowed to warm to room temperature and stir
overnight (14 h). The mixture was filtered and the drying agent was
washed with CH.sub.2Cl.sub.2 (2.times.10 mL). The filtrate was
concentrated under reduced pressure to afford 8.4 g (100%) of an
oil which was taken onto the next step without further
purification.
[1114] Step B
[1115] To a solution of the imine (8.4 g, 40.2 mmol) from Step A in
CH.sub.2Cl.sub.2 (60 mL) at room temperature was added Et.sub.3N
(6.2 mL, 44.5 mmol) followed by dropwise addition of TMSCI (5.7 mL,
44.5 mmol). The mixture was stirred for 6 h at room temperature
whereupon the ppt that had formed was filtered off and washed with
CH.sub.2Cl.sub.2 (2.times.10 mL). The combined filtrate was
concentrated under reduced pressure and was taken up in
Et.sub.2O/hexane (1:1/150 mL). The precipitate was filtered off and
the filtrate was concentrated under reduced pressure to afford 10.1
g (89%) of the protected imine as an oil. This material was taken
onto the next step without further purification.
[1116] Step C
[1117] To a solution of EtI (4.0 g, 25.6 mmol) in Et.sub.2O (40 mL)
at -78.degree. C. was added t-BuLi (30.1 mL, 51.2 mmol, 1.7 M in
pentane) and the mixture was stirred for 10 min. The mixture was
warmed to room temperature, stirred for 1 h, and was recooled to
-40.degree. C. A solution of the imine (6.0 g, 21.4 mmol) from Step
B in Et.sub.2O (30 mL) was added dropwise via addition funnel to
afford a bright orange mixture. The reaction mixture was stirred
for 1.5 h at -40.degree. C. then 3M HCl (50 mL) was added and the
mixture was allowed to warm to room temperature. Water (50 mL) was
added and the layers were separated. The aqueous layer was
extracted with Et.sub.2O (2.times.30 mL) and the organic layers
were combined and discarded. The aqueous layer was cooled to
0.degree. C. and carefully treated with solid NaOH pellets until
pH=12 was attained. The aqueous layer was extracted with Et.sub.2O
(3.times.30 mL) and the combined layers were washed with brine
(1.times.30 mL). The organic layer was dried (Na.sub.2SO.sub.4),
filtered, and concentrated under reduced pressure to afford 4.8 g
(94% yield) of the amine as an oil. This material was taken on
crude to the next step without further purification.
[1118] Step D
[1119] To a solution of amine (4.5 g, 18.8 mmol) from Step C in
MeOH (80 mL) at room temperature was added MeNH.sub.2 (25 mL, 40%
in water) followed by addition of a solution of H.sub.5IO.sub.6
(14.0 g, 61.4 mmol) in H.sub.2O (25 mL). The heterogenous mixture
was stirred for 1.5 h (until the reaction was complete by TLC) and
the precipitate was filtered off. The resulting filtrate was
diluted with water (50 mL) and the mixture was extracted with
Et.sub.2O (4.times.60 mL). The combined organic layers were
concentrated to a volume of .about.30 mL whereupon 3M HCl (75 mL)
was added. The mixture was stirred overnight (12 h at room
temperature) after which the mixture was concentrated to remove the
volatiles. The aqueous layer was extracted with Et.sub.2O
(3.times.40 mL) and the organic layers were discarded. The aqueous
layer was cooled to 0.degree. C. and was carefully treated with
solid NaOH pellets until pH.about.12 was reached. The aqueous layer
was extracted with Et.sub.2O (3.times.60 mL) and the combined
organic layers were dried (MgSO.sub.4). The organic layer was
concentrated under reduced pressure to afford 2.8 g(97% yield) of
the desired amine as an oil [MH.sup.+ 154]. This compound was
proven to be >85% pure by .sup.1H NMR and was used crude in the
subsequent coupling step.

[1670] Oxallyl chloride (3.5 mL) and two drops of DMF was added to
the product from Step A above (.about.13 mmol) dissolved in
dichloromethane (100 mL). After stirring at RT overnight, the
mixture was concentrated in vacuo, diluted with dichloromethane (50
mL), cooled to 0.degree. C. Dimethylamine in THF (20 mL of 2N) and
TEA (8 mL) were added. After 3 hr of stirring, the mixture was
concentrated in vacuo, aq NaOH (1M) was added, and the mixture was
extracted with dichloromethane. The pH of the aq layer was adjusted
to pH=2 using 6N HCl (aq), and extracted with dichloromethane. The
combiuned organic extracts were washed with brine, dried,
concentrated in vacuo, and the product purified by silica gel
chromatography (700 mL dichloromethane/20 mL MeOH/1 mL AcOH) to
give the title compound (800 mg, 27% for two steps).
[1671] Step C
[1672] Following a similar procedure as that used in Preparative
Example 10.55 Step C, except using the product from Step B above
(780 mg), the title compound was obtained (0.46 g, 68%).
PREPARATIVE EXAMPLE 1314
[1673] 1627
[1674] Step A
[1675] Methyl-4-bromo-3-hydroxy-2-thiophenecarboxylate (20 g, 84.36
mmol) was dissolved in 400 mL of acetone. Potassium carbonate (58
g, 420.3 mmol) was added followed by iodomethane (45 mL, 424 mmol).
The resulting mixture was heated at reflux for 4.5 h. After
cooling, the mixture was filtered through a thin Celite pad,
rinsing with methylene chloride. The filtrate was concentrated in
vacuo to give 22.5 g of
methyl-4-bromo-3-methoxy-2-thiophenecarboxylate (crude, 100%,
MH.sup.+=251.0) as a dark green solid.
[1676] Step B
[1677] The product from Step A above (22.5 g, 84.36 mmol) was
dissolved in 60 mL of tetrahydrofuran and added with 125 mL of a
1.0 M NaOH aqueous solution. The mixture was stirred at room
temperature for 4 d, then washed with ether (60 mL.times.2),
acidified to pH.about.2 using a 1.0 M HCl aqueous solution. Solids
were precipitated out after acidification, and collected by
filtration. The solid was dissolved in methylene chloride-ethyl
acetate (.about.4:1, v/v). The organic solution was washed with
H.sub.2O and brine, dried with Na.sub.2SO.sub.4, and concentrated
in vacuo to a light yellow solid, further dried on hight vacuum,
yielding 17.95 g of 4-bromo-3-methoxy-2-thiophene carboxylic acid
(90%, MH.sup.+=237.0).
[1678] Step C
[1679] The carboxylic acid (3.26 g, 13.75 mmol) available from Step
B above was treated with 30 mL of concentrated sulfuric acid. The
mixture was sealed in a one-neck round bottom flask, and heated at
65.degree. C. for 4.5 h. After cooled to room temperature, the
mixture was poured into 200 mL of crushed ice, and extracted with
methylene chloride (100 mL.times.3). The organic extracts were
combined, washed successively with H.sub.2O (50 mL.times.2), sat.
NaHCO.sub.3 (50 mL.times.3), and brine (50 mL). The organic
solution was dried with Na.sub.2SO.sub.4, and concentrated in vacuo
to a dark brown oil, which was purified by flash column
chromatography (biotage, SiO.sub.2 column) using hexanes-methylene
chloride (3:1, v/v) as eluents. Removal of solvents afforded 1.83 g
of 3-bromo4-methoxy thiophene (69%) as a light yellow oil.
[1680] Step D
[1681] To a stirred solution of 3-bromo-4-methoxythiophene (550 mg,
2.85 mmol), prepared in Step C above, in 30 mL of methylene
chloride at -78.degree. C. was added dropwise along the inside wall
of the flask chlorosulfonic acid (0.48 mL, 7.21 mmol). The mixture
was stirred at -78.degree. C. for 10 min, continued at room
temperature for 1 h, and filtered through a 1-in silica gel pad,
rinsing with methylene chloride. The filtrate was concentrated in
vacuuo to give 270 mg of 4-bromo-3-methoxy-2-thiophene
sulfonylchloride (33%) as a light yellow oil.
[1682] Step E
[1683] To a stirred solution of thiophene sulfonylchloride (270 mg,
0.926 mmol) prepared in Step D above in 15 mL of methylene chloride
at room temperature was added triethylamine followed by
N-methyl-tertbutylamine (0.25 mL, 2.094 mmol). After 20 h, the
mixture was diluted with 50 mL of methylene chloride, and washed
with H.sub.2O and brine. The organic solution was dried over
Na.sub.2SO.sub.4, filtered, and concentrated to an oily residue,
which was purified by preparative TLC (methylene chloride as
eluent) to afford 73 mg of the titled bromo-sulfonamide (23%) as a
near colorless oil.
[1684] Step F
[1685] A one-neck round bottom flask was charged with
bromo-sulfonamide (73 mg, 0.2133 mmol, from Step E above),
palladium acetate (5 mg, 0.0223 mmol), binap (0.03212 mmol), cesium
carbonate (139 mg, 0.4266 mmol), and benzophenonimine (0.06 mL,
0.358 mmol). The mixture was evacuated via house vacuum, and
refilled with nitrogen. A 3 mL of anhydrous toluene was added. The
mixture was evacuated again, refilled with nitrogen, and heated at
reflux for 2.5 d. After cooled to room temperature, methylene
chloride (50 mL) was added, the mixture was filtered through a
Celite pad, rinsing with methylene chloride. The filtrated was
concentrated in vacuo to give 205 mg (crude, MH.sup.+=443.1) of the
desired imine product as a dark brown oil, used in next step
without purification.
[1686] Step G
[1687] The imine from Step F above (205 mg, crude, 0.2133 mmol) was
dissolved in 5 mL of methanol, and added with sodium acetate (81
mg, 0.9873 mmol) followed by hydroxylamine hydrochloride (68 mg,
0.98 mmol). The mixture was stirred at room temperature for 6.5 h,
quenched with the addition of 10 mL of a 1.0 M NaOH aqueous
solution. The aqueous mixture was extracted with methylene chloride
(30 mL.times.3). The extracts were combined, washed with brine,
dried by Na.sub.2SO.sub.4, and concentrated in vacuo to a dark
yellow oil, which was purified by preparative TLC (methylene
chloride-methanol=100:1, v/v) to give 34 mg (57% over two steps,
MH.sup.+=279.0) of methoxy-thiophenesulfonamide amine as a light
yellow oil, solidified on standing.
[1688] Step H
[1689] To a stirred suspension of sodium hydride (60%, 45 mg, 1.13
mmol) in 3 mL of anhydrous N,N'-dimethylformamide (DMF) was added
dropwise ethanethiol (0.1 mL, 1.34 mmol). After 10 min, the mixture
tured into a clear solution, and 1 mL of this solution was taken up
in a syringe and added dropwise to a stirred solution of
methoxy-thiophenesulfonamide amine in 1 mL of DMF. The mixture was
heated up to 95.degree. C., and continued for 3.5 h. After cooling,
the mixture was poured into 20 mL of a 1.0 M NaOH aqueous solution.
The aqueous mixture was washed with methylene chloride (30
mL.times.3). The organic washings were combined, re-extracted with
a 1.0 M NaOH aqueous solution (15 mL) and H.sub.2O (15 mL). The
aqueous layer and aqueous extracts were combined, adjusted to
pH.about.6 using a 1.0 M HCl aqueous solution, and extracted with
methylene chloride (75 mL.times.3). The organic extracts were
washed with brine, dried (Na.sub.2SO.sub.4), and concentrated in
vacuo to a dark yellow oil. This oil was dissolved in ethyl acetate
(50 mL), washed with H.sub.2O (10 mL.times.2) and brine (10 mL).
The organic solution was dried (Na.sub.2SO.sub.4), and concentrated
in vacuo to afford 36 mg (100%, MH.sup.+=265.0) of
hydroxyl-thiophene sulfonamide amine as a yellow oil.
PREPARATIVE EXAMPLE 1315
[1690] 1628
[1691] Step A
[1692] Following the procedures described in Preparative Example
1314 Step E, 4-bromo-3-methoxy-2-thiophene-sulfonyl chloride (190
mg, 0.65 mmol, available from Step D, Preparative Example 1314) was
converted to the titled tert-butyl sulfonamide (56 mg, 26%,
MH.sup.+=328.1) upon treatment of triethylamine (0.28 mL, 2.0 mmol)
and tert-butylamine (0.15 mL, 1.43 mmol) in 10 mL of methylene
chloride.
[1693] Step B
[1694] tert-Butyl sulfonamide (98 mg, 0.3 mmol) available from Step
A above was converted to the imine product (296 mg, crude,
MH.sup.+=429.1) by using the procedure described in Step F of
Preparative Example 1314.
[1695] Step C
[1696] The imine product (296 mg, crude, .about.0.3 mmol) was
transformed to the desired thiophene-amine (23 mg, 30% over two
steps, MH.sup.+=265.0) by using the procedure described in Step G
of Preparative Example 1314.
[1697] Step D
[1698] If one were to apply the procedure set forth in Step H of
Preparative Example 1314, but using the thiophene amine available

Preparative example 13.29) was converted to titled
diethylsulfonamido thiophene imine (MH.sup.+=429.1)
[1702] Step B
[1703] Thiophene-imine (1.5 g, 3.5 mmol), available from Step A
above, was dissolved in 30 mL of CH.sub.2Cl.sub.2, and added with
potassium carbonate (1.2 g, 8.70 mmol) followed by drop wise
addition of bromine (0.32 mL, 6.25 mmol). After stirred for 2 d,
H.sub.2O was added. The two layers were separated. The aqueous
layer was extracted with CH.sub.2Cl.sub.2 (50 mL.times.2). The
organic layers were combined, washed with a 10%
Na.sub.2S.sub.2O.sub.3 aqueous solution (40 mL.times.2) and brine
(40 mL), dried over Na.sub.2SO.sub.4, and concentrated in vacuo to
a dark brown oil. This oil was separated by preparative TLC
(CH.sub.2Cl.sub.2 as eluent), to give 0.96 g (54%) of the desired
bromo-imine as a bright yellow oil (M.sup.+=507, M+2=509)
[1704] Step C
[1705] Bromo-imine (0.95 g, 1.87 mmol), available from Step B
above, was dissolved in 15 mL of anhydrous THF, cooled in a
-78.degree. C. bath, and treated with a 2.5 M solution of n-butyl
lithium in hexanes (1.2 mL, 3.0 mmol) drop wise along the side wall
of the flask. After 30 min, lodomethane (0.35 mL, 5.62 mmol) was
added drop wise. Reaction was continued for 5 h, during which time
the cooling bath was allowed to warm slowly to 0.degree. C. The
mixture was quenched by H.sub.2O (25 mL), and extracted with
CH.sub.2Cl.sub.2 (50 mL.times.2). The organic extracts were washed
with brine, dried with Na.sub.2SO.sub.4, and concentrated in vacuo
to give 0.93 g (crude, >100%) of the desired methylated imine as
a dark yellow oil (MH.sup.+=443.1)
[1706] Step D
[1707] The crude methyl-imine (0.93 g), prepared in step C above,

EXAMPLE 200
[1713] 1977
[1714] The thiadiazoleoxide from Preparative Example 22.1 (55 mg,
0.17 mmol) was added to R-2-phenylpropylamine (0.024 mL, 0.17 mmol)
in methanol (2 ml) with diiospropylethylamine (100 .mu.L). The
reaction mixture was microwaved at 100 W for 4 hr then purified by
preparative HPLC. Concentration of desired fractions gave the pure
product (12.4 mg, 18%). MH.sup.+=413.9.
EXAMPLE 201
[1715] 1978
[1716] The thiadiazoleoxide from Preparative Example 22.2 (56 mg,
0.2 mmol) was added to 2-amino-6-cyanophenol (27 mg, 0.2 mmol) in
methanol (2 ml) with diiospropylethylamine (100 .mu.L). The
reaction mixture was microwaved at 100 W for 24 hr then purified by
preparative HPLC. Concentration of desired fractions gave the pure
product (11 mg, 15%). MH.sup.+=367.9.
EXAMPLE 201A
[1717] 1979
[1718] To a solution of the Thiadiazole mono-oxide intermediate
from Preparative Example 22.1 (100 mg, 0.3086 mmol) and the Furyl
amine from Preparative Example 75.1 (43 mg, 0.3086 mmol) in
methanol (2 mL) was added sodium trifluoro acetate (84 mg, 0.6172
mmol), followed by drop wise addition of diisopropylethylamine (80
mg, 0.6172 mmol). The reaction mixture was stirred over night at
room temperature, solvents were removed under reduced pressure and
the product was purified by preparative thin layer chromatography
using Dichloromethane-Methanol (20:1) to afford the compound as a
white solid. (Yield: 98 mg, 74%, m.p=140.degree. C.)
