A novel series of substituted 1,2,3-benzotriazines and pyrido[3,2-d]-1,2,3-triazines were synthesized. The abilities of these compounds to inhibit the VEGFR-2 kinase activity and the proliferation of human microvascular endothelial cells (MVECs) were determined. 6-Methoxy-4-substituted-1,2,3-benzotriazines and 4-substituted-6-chloro-pyrido[3,2-d]-1,2,3-triazines have the abilities of inhibiting the VEGFR-2 kinase activity, but only the 4-substituted-6-chloro-pyrido[3,2-d]-1,2,3-triazines exhibit good growth inhibitory effects on MVECs. Compound 6-chloro-4-(3-trifluoromethylanilino)-pyrido[3,2-d][1,2,3]triazin (11d) is less half active than PTK787 to inhibit the VEGFR-2 kinase activity, but is more active than PTK787 to inhibit the growth of MVECs. The potential binding modes of 6d, 11d, and CTZ12 in complex with their putative intracellular target, VEGFR-2, were predicted using Surflex-Dock.
