Solid-phase synthesis of naphthylamidines as factor VIIa/tissue factor inhibitors

Reductive amination followed by acylation of polymer-linked formyl aryl amidines generate combinatorial libraries of aryl amidines 8-13. Potent small molecule naphthylamidine inhibitors 12 (Ki<100 nM) of FVIIa/TF have been discovered and their activity against other serine proteases in the coagulation cascade is reported.
