Description
[0001] The invention relates to pharmaceutical compositions
comprising casein kinase 1 delta (CK1.delta.) inhibitors and to the
use of said inhibitors in the treatment of neurodegenerative
disorders such as Alzheimer's disease.
[0002] Alzheimer's disease (AD; also known as senile dementia of
the Alzheimer type (SDAT), primary degenerative dementia of the
Alzheimer's type (PDDAT), or Alzheimer's) is the most common form
of dementia. Most often, Alzheimer's disease is diagnosed in people
over 65 years of age, although the less-prevalent early-onset
Alzheimer's can occur much earlier. In 2006, there were 26.6
million sufferers worldwide. Alzheimer's is predicted to affect 1
in 85 people globally by 2050.
[0003] Alzheimer's disease is a neurodegenerative disease
characterised by the presence of senile plaques and neurofibrillary
tangles in the brain. The degree of dementia at death correlates
better with neurofibrillary tangle numbers than with senile plaques
counts. The presence of neurofibrillary tangles in neurons results
in the death of those neurons, implying that prevention of tangle
formation is an important therapeutic goal. The principal protein
that forms the neurofibrillary tangle is the microtubule-associated
protein, tau, which assembles into filaments that have the
appearance of twisting about each other in pairs and are referred
to as paired helical filaments (PHF). PHF are present in different
locations in degenerating neurons in the Alzheimer brain and when
many aggregate in the neuronal cell body, they produce the
neurofibrillary tangle (Lee et al, 2001).
[0004] Intraneuronal deposits of tau in the form of typical
neurofibrillary tangles of AD or other morphologically distinct tau
aggregates in a number of other neurodegenerative diseases, is the
basis for grouping these conditions as tauopathies. Thus, in
addition to AD, the main examples of the tauopathies are
frontotemporal dementia with Parkinsonism linked to chromosome 17
(FTDP-17), progressive supranuclear palsy (PSP), Pick's disease,
corticobasal degeneration, and multisystem atrophy (MSA). The
intracellular tau deposits (usually neuronal but can also be glial)
are all filamentous and mostly in a hyperphosphorylated state
compared to the level of phosphorylation of tau from control human
brain. In the case of AD, this hyperphosphorylated tau is often
referred to as PHF-tau because it is derived from the PHF.
[0005] Tau is a phosphoprotein, the function of phosphorylation
remaining to be unequivocally established. However, increased
phosphorylation of tau on multiple serine and threonine residues
reduces the ability of tau to promote microtubule assembly and to
stabilise assembled microtubules, effects that have been
demonstrated both in vitro and in cells. Many studies have shown
that PHF-tau from AD brain is more heavily phosphorylated on serine
and threonine than tau from control brain. This has been
demonstrated partly by protein sequencing and partly by
demonstrating that certain monoclonal antibodies only label either
PHF-tau or non-phosphorylated tau and not PHF-tau; the epitopes for
many of these antibodies have been mapped to particular
phosphorylated residues present in PHF-tau and absent from control
brain tau. The pathological tau from most other cases of other
tauopathies seems to be similarly hyperphosphorylated to
PHF-tau.
[0006] These findings strongly imply that similar abnormalities in
regulating phosphorylation of tau are shared by all the tauopathies
including AD.
[0007] A number of proline-directed and non-proline directed
protein kinases have been suggested to have a role in the
generation of PHF-tau in Alzheimer brain, including casein kinase
1. Mammalian casein kinase-1 exists as multiple isoforms
CK1.alpha., CK1.beta., CK1y1, CK1y2, CK1y3, CK1.delta. and
CK1.epsilon.. The role of CK1.delta. as a potential tau kinase is
of particular interest since it has been reported that CK1.delta.
protein is increased more than 30-fold in the hippocampus of
Alzheimer brain compared to equivalent controls (Ghoshal, N. et al
(1999) Am. J. Pathol 155, 1163-1172) while its mRNA content is
increased 24-fold (Yasojima, K. et al (2000) Brain Res 865,
116-120) and CK1 has also been shown to be tightly associated with
PHF (Kuret, J. et al (1997) J. Neurochem 69, 2506-2515). CK1.delta.
has also been reported to phosphorylate tau at two epitopes
detecting using phospho-specific monoclonal antibodies to tau, and
exogenous expression of CK1.delta. in non-neuronal cells reduces
binding of tau to microtubules (Li, G. et al (2004) J. Biol. Chem.
279, 15938-15945). Of note in the context of Alzheimer's disease is
a report that CK1 activity is stimulated by amyloid beta-peptide
(A.beta.), a component of the senile neuritic plaques that,
together with tangles, characterise Alzheimer brain (Chauhan, A. et
al (1993) Brain Res. 629, 47-52). Additional evidence for possible
involvement of CK1 in Alzheimer's disease comes from the reported
influence of CK1 in the regulation of A.beta. production in neurons
(Flajolet, M. et al (2007) PNAS USA 104, 4159-4164). Further work
has confirmed that at least 6 newly identified phosphorylation
sites in PHF-tau (all on serine or threonine residues) can be
generated by CK1.delta.. The finding that a number of
phosphorylation sites in PHF-tau for which CK1 is a strong
candidate kinase, including three for which it is the only known
kinase, implies that CK1 may make an important contribution to the
pathogenesis of Alzheimer's disease (Hanger et al (2007) J. Biol.
Chem. 282, 23645-23654).
[0008] There is therefore a need for CK1.delta. inhibitors which
may be of potential therapeutic benefit in the treatment of
neurodegenerative diseases, such as tauopathies including
Alzheimer's disease, frontotemporal dementia with Parkinsonism
linked to chromosome 17 (FTDP-17), progressive supranuclear palsy
(PSP), Pick's disease, corticobasal degeneration, and multisystem
atrophy (MSA).

[0165] Compounds of formula 1-1002 are either commercially
available or may be prepared in accordance with known synthetic
procedures.
[0166] According to a further aspect of the invention there is
provided a pharmaceutical composition comprising any one of the
compounds of formulae (IA)-(IH) for use in the treatment of a
neurodegenerative disorder, such as tauopathies.
[0167] The pharmaceutical compositions of the invention may
comprise, in addition to one of the above substances, a
pharmaceutically acceptable excipient, carrier, buffer, stabiliser
or other materials well known to those skilled in the art. Such
materials should be non-toxic and should not interfere with the
efficacy of the active ingredient. The precise nature of the
carrier or other material may depend on the route of
administration, e. g. oral, intravenous, cutaneous or subcutaneous,
nasal, intramuscular, intraperitoneal routes.
[0168] Pharmaceutical compositions for oral administration may be
in tablet, capsule, powder or liquid form. A tablet may include a
solid carrier such as gelatin or an adjuvant.
[0169] Liquid pharmaceutical compositions generally include a
liquid carrier such as water, petroleum, animal or vegetable oils,
mineral oil or synthetic oil.

injection at the site of affliction, the active ingredient will be
in the form of a parenterally acceptable aqueous solution which is
pyrogen-free and has suitable pH, isotonicity and stability. Those
of relevant skill in the art are well able to prepare suitable
solutions using, for example, isotonic vehicles such as Sodium
Chloride Injection, Ringer's Injection, Lactated Ringer's
Injection. Preservatives, stabilisers, buffers, antioxidants and/or
other additives may be included, as required.
[0172] The compounds of formulae (IA)-(IH) are believed to be
casein kinase 1 delta (CK1.delta.) inhibitors. Certain compounds of
formulae (IA)-(IH) have inhibitory activity of greater than 5%, in
particular greater than 10%, more particularly greater than 25%,
yet more particularly greater than 50%, especially greater than
75%, such as greater than 90%. Such compounds may be useful in the
treatment in neurodegenerative disorders such as tauopathies.
Tauopathies are conditions which are characterised by
neurofibrillary tangles or aggregates of the tau protein.
Tauopathies are a recognised class of conditions known to those
skilled in the art and include Alzheimer's disease, frontotemporal
dementia with Parkinsonism linked to chromosome 17 (FTDP-17),
progressive supranuclear palsy (PSP), Pick's disease, corticobasal
degeneration, multisystem atrophy (MSA), neurobasal degeneration
with iron accumulation, type 1 (Hallervorden-Spatz), argyrophilic
grain dementia, Down's syndrome, diffuse neurofibrillary tangles
with calcification, dementia pugilistica,
Gerstmann-Straussler-Scheinker disease, myotonic dystrophy,
Niemann-Pick disease type C, progressive subcortical gliosis, prion
protein cerebral amyloid angiopathy, tangle only dementia,
postencephalitic parkinsonism, subacute sclerosing panencephalitis,
Creutzfeldt-Jakob disease, amyotrophic lateral
sclerosis/parkinsonism-dementia complex, non-Guamanian motor neuron
disease with neurofibrillary tangles/dementia, and Parkinson's
disease. The intracellular tau deposits are usually neuronal or
glial and are filamentous and generally in a hyperphosphorylated
state as compared to the level of phosphorylation in tau from
control human brain. In the case of AD, this hyperphosphorylated
tau is often referred to a paired helical filament tau (PHF) tau
because it is derived from the PHF. In one embodiment, the
tauopathy comprises Alzheimer's disease.
[0173] According to a further aspect of the invention, there is
provided a method of treating a neurodegenerative disorder, such as
tauopathies, which comprises administering a therapeutically
