thrombin and P2 pyridine N-oxide inhibitor complex structure

Overview

In this study, we have demonstrated that the critical hydrogen bonding, motif of the established 3-aminopyrazinone thrombin inhibitors can be, effectively mimicked by a 2-aminopyridine N-oxide. As this peptidomimetic, core is more resistant toward oxidative metabolism, it also overcomes the, metabolic liability associated with the pyrazinones. An optimization study, of the P(1) benzylamide delivered the potent thrombin inhibitor 21 (K(i) =, 3.2 nM, 2xaPTT = 360 nM), which exhibited good plasma levels and half-life, after oral dosing in the dog (C(max) = 2.6 microM, t(1/2) = 4.5 h).
