Phenyltriazolinones as potent factor Xa inhibitors.
Bioorg.Med.Chem.Lett., 20:1373-1377, 2010

PubMed Abstract: We have discovered that phenyltriazolinone is a novel and potent P1 moiety for coagulation factor Xa. X-ray structures of the inhibitors with a phenyltriazolinone in the P1 position revealed that the side chain of Asp189 has reoriented resulting in a novel S1 binding pocket which is larger in size to accommodate the phenyltriazolinone P1 substrate.
