Abstract

N-oxides of amino containing 6-aryl pyrido2,3-d!-pyrimidine 7-imines, 7-ones, and 7-thiones have the formula ##STR1## where A and B are linkers, Ar is aryl, R.sub.2 is aklyl, X is O, S, or NH, or NAcyl, and R.sub.5 and R.sub.6 are alkyl. The compounds are inhibitors of protein tyrosine kinases and cyclin-dependent kinases, and are thus useful in treating cellular proliferation mediated thereby. The compounds are especially useful in treating cancer, atherosclerosis, restenosis, and psoriasis.
