Novel Potent and Selective Thrombin Inhibitors Based on a Central 1,4-Benzoxazin-3(4H)-one Scaffold
摘要:
Novel thrombin inhibitors with the central 1,4-benzoxazine-3(4H)-one scaffold, benzamidine P-1 arginine side chain mimetic and various P-3 moieties are described. 3-(Benzyl(2-(4-carbamimidoylbenzyl)-4-methyl-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-7-yl)amino)-3-oxopropanoic acid (7b), the most potent compound in the series, exhibited a K-i of 2.6 nM in vitro for thrombin and high selectivity against trypsin and factor Xa.
