Pyrido{2,3-d}pyrimidines for inhibiting protein tyrosine kin ase mediated cellular proliferation

摘要

6-Aryl pyrido[2,3-d]pyrimidine 7-imines, 7-ones, and 7-thiones o f formula (I) are inhibitors of protein tyrosine kinases, and are thus useful in treating cellular proliferation mediated thereby. The compounds are especially useful in treating cancer, atherosclerosis, restenosis, and psoriasis.
