This invention relates to amidopyrazole compounds that are inhibitors of Interleukin receptor-associated kinases, in particular IRAK-4, and are useful in the treatment of cellular proliferative diseases, for example, cancer, hyperplasia, restenosis, cardiac hypertrophy, immune disorders and inflammation.

IRAK4 is a critical upstream kinase in the IL-1R/TLR signaling pathway. Inhibition of IRAK4 is hypothesized to be beneficial in the treatment of autoimmune related disorders. A screening campaign identified a pyrazole class of IRAK4 inhibitors that were determined by X-ray crystallography to exhibit an unusual binding mode. SAR efforts focused on the identification of a potent and selective inhibitor with good aqueous solubility and rodent pharmacokinetics. Pyrazole C-3 piperidines were well tolerated, with N-sulfonyl analogues generally having good rodent oral exposure but poor solubility. N-Alkyl piperidines exhibited excellent solubility and reduced exposure. Pyrazoles possessing NI pyridine and fluorophenyl substituents were among the most active. Piperazine 32 was a potent enzyme inhibitor with good cellular activity. Compound 32 reduced the in vivo production of proinflammatory cytokines and was orally efficacious in a mouse antibody induced arthritis disease model of inflammation.

3-(Pyridin-3-yl)-1-p-tolyl-1H-pyrazolo[3,4-d]thiazol-5-amine was used as a key synthon for a one-pot two- and three-component synthesis of new fused heterocyclic moieties as pyrazolo[3,4-d]thiazole derivatives containing new fused ring pyrimidines or imidazoles. The compounds were synthesized by using microwave irradiation as an eco-friendly technique besides the conventional heating. All the newly
