The present invention relates to imidazo[1,2-a]pyrimidine derivatives, that are useful for treating cellular proliferative diseases, for treating disorders associated with MET activity, and for inhibiting the receptor tyrosine kinase MET. The invention also related to compositions which comprise these compounds, and methods of using them to treat cancer in mammals.

Tyrosine kinase inhibitors

This invention describes novel pyrazole compounds of formula (IV) wherein Ring D is a 5-7 membered monocyclic ring or 8-10 membered bicyclic ring selected from aryl, heteroaryl, heterocyclyl or carbocyclyl; R?x and Ry? are independently selected from T-R3, or taken together with their intervening atoms to form a fused, unsaturated or partially unsaturated, 5-8 membered ring having 1-3 ring heteroatoms selected from oxygen, sulfur, or nitrogen; and R2, R2', and T, and R3 are as described in the specification. The compounds are useful as protein kinase inhibitors, especially as inhibitors of aurora-2 and GSK-3, for treating diseases such as cancer, diabetes and Alzehimer's disease.

The present invention provides a compound of formula I: or a pharmaceutically acceptable salt or mixtures thereof. These compounds are inhibitors of protein kinases, particularly inhibitors of GSK mammalian protein kinase, and more particularly inhibitors of GSK-3 mammalian protein kinase. The invention also provides pharmaceutically acceptable compositions comprising the compounds of the invention and methods of utilizing those compounds and compositions in the treatment of various protein kinase mediated disorders.

Compositions useful as inhibitors of protein kinases

The invention provides a novel class of compounds of formula 1, pharmaceutical compositions comprising such compounds and methods of using such compounds to treat or prevent diseases or disorders associated with abnormal or deregulated kinase activity, particularly diseases or disorders that involve abnormal activation of B-Raf

Substituted 2-anilinopyrimidines useful as protein kinase inhibitors

Compounds of general formula (1) are described wherein: Ar is an optionally substituted aromatic group; R2 is a hydrogen or halogen atom or a group -X1-R2a where X1 is a direct bond or a linker atom or group, and R2a is an optionally substituted straight or branched chain alkyl, alkenyl or alkynyl group; R3 is an optionally substituted heterocycloalkyl group; and the salts, solvates, hydrates and N-oxides thereof. The compounds are selective protein tyrosine kinase inhibitors, particularly the kinases ZAP-70 and syk and are of use in the prophylaxis and treatment of immune or allergic diseases and diseases involving inappropriate platelet activation.

2-Pyrimidineamine derivatives and processes for their preparation

Compounds of general formula (1): ##STR1## are described wherein Het is an optionally substituted heteroaromatic group; R 1 is a hydrogen atom or a straight or branched chain alkyl group; R 2 is a hydrogen or halogen atom or a group --X 1 --R 2a where X 1 is a direct bond or a linker atom or group, and R 2a is an optionally substituted straight or branched chain alkyl, alkenyl or alkynyl group; R 3 is an optionally substituted aromatic or heteroaromatic group; and the salts, solvates, hydrates and N-oxides thereof. The compounds are selective protein kinase inhibitors, particularly the kinases p56 lck , ZAP-70 and protein kinase C and are of use in the prophylaxis and treatment of immune diseases, hyperproliferative disorders and other diseases in which inappropriate protein kinase action is believed to have a role.

Substituted 2-pyrimidineamines and processes for their preparation

Compounds of general formula (1) are described wherein Het is an optionally substituted heteroaromatic group; R1 is a hydrogen atom or a straight or branched chain alkyl group; R2 is a hydrogen or halogen atom or a group -X1-R2a where X1 is a direct bond or a linker atom or group, and R2a is an optionally substituted straight or branched chain alkyl, alkenyl or alkynyl group; R3 is an optionally substituted aromatic or heteroaromatic group; and the salts, solvates, hydrates and N-oxides thereof. The compounds are selective protein kinase inhibitors, particularly the kinases p56lck, ZAP-70 and protein kinase C and are of use in the prophylaxis and treatment of immune diseases, hyperproliferative disorders and other diseases in which inappropriate protein kinase action is believed to have a role.

Substituted 2-pyrimidineamines, their preparation and their use as proteine kinase inhibitors

Fused polycyclic 2-aminopyrimidines of formula (1) wherein Ar is an optionally substituted aromatic or heteroaromatic group; X is a carbon or nitrogen atom; Y is a carbon or nitrogen atom; Z is a linker group; A together with X and Y forms an optionally substituted monocyclic or bicyclic aromatic or heteroaromatic group; and the salts, solvates, hydrates and N-oxides thereof are described. The compounds are potent and selective inhibitors of the protein tyrosine kinases p56lck and p59fyn and are of use in the prophylaxis and treatment of immune diseases, hyperproliferative disorders and other diseases in which inappropriate p56lck and/or p59fyn activity is believed to have a role.
