Discovery of N-[2-Hydroxy-6-(4-methoxybenzamido)phenyl]-4- (4-methyl-1,4-diazepan-1-yl)benzamide (Darexaban, YM150) as a Potent and Orally Available Factor Xa Inhibitor
摘要:
Inhibitors of factor Xa (FXa), a crucial serine protease in the coagulation cascade, have attracted a great deal of attention as a target for developing antithrombotic agents. We previously reported findings from our optimization study of a high-throughput screening (HTS) derived lead compound la that resulted in the discovery of potent amidine-containing FXa inhibitors represented by compound 2. We also conducted an alternative optimization study of la without incorporating a strong basic amidine group, which generally has an adverse effect on the pharmacokinetic profile after oral administration. Replacement of 4-methoxybenzene with a 1,4-benzodiazepine structure and introduction of a hydroxy group at the central benzene led to the discovery of the potent and orally effective factor Xa inhibitor 14i (darexaban, YM150). Subsequent extensive study revealed a unique aspect to the pharmacokinetic profile of this compound, wherein the hydroxy moiety of 141 is rapidly transformed into its glucuronide conjugate 16 (YM-222714) as an active metabolite after oral administration and it plays a major role in expression of potent anticoagulant activity in plasma. The distinctive, potent activity of inhibitor 14i after oral dosing was explained by this unique pharmacokinetic profile and its favorable membrane permeability. Compound 14i is currently undergoing clinical development for prevention and treatment of thromboembolic diseases.
