Abstract

5-Aryl-pyrrolo[2,3-d]pyrimidines incorporating different N7-substituents have been prepared and evaluated for their inhibitory potency towards the tyrosine kinase c-Src. Optimization of these compounds resulted in highly potent c-Src inhibitors, some (e.g. 4g, 6g, 7h, 8l ) with excellent specificity towards other receptor and nonreceptor tyrosine kinases. In addition compounds 4g, 5b and 5c are characterized by a good pharmacokinetic profile.

Keywords: tyrosine kinase inhibitor, c-src inhibitor
