Six novel N-4-substitutedphenyl-6-substitutedphenylmethy1-7H-pyrrolo[2,3-d]pyrimidine-2,4-diamines were synthesized as multiple receptor tyrosine kinase (RTK) inhibitors and antitumor agents. An improvement in the inhibitory potency against epidermal growth factor receptor (EGFR), vascular endothelial growth factor receptor 1 (VEGFR-1) and vascular endothelial growth factor receptor 2 (VEGFR-2) assays and in the A431 cellular proliferation assay was observed for compounds 8-13 over the previously reported 5-7. Three compounds (8.9 and 13) demonstrated potent, multiple RTK inhibition and were more potent or equipotent compared to the lead compounds 5 and 7 and the standard compounds. Compounds 10 and 12 showed potent inhibition of VEGFR-2 over EGFR, platelet-derived growth factor receptor-p (PDGFR-p) and VEGFR-1. The results indicate that the RIM inhibitory profile could be modulated with slight variations to the N-4-aryl-6-substitutedphenylmethyl-7H-Pyrrolo[2,3-d]wrimidine-2,4-diamino scaffold.
