Optimization of a coagulation factor VIIa inhibitor found in factor Xa inhibitor library☆
摘要:
An inhibitor of the complex of factor Vila and tissue factor (fVIIa/TF), 2-substituted-4-amidinophenylpyruvic acid la, was structurally modified with the aim of increasing its potency and selectivity. The lead compound la was originally found in our factor Xa (fXa) inhibitor library on the basis of structural similarity of the primary binding sites of tVIIa and fXa. The design was based on computational docking studies using the extracted active site of tVIIa. Compound 1j was found to inhibit factor VIIa/TF at nanomolar concentration with improved selectivity versus fXa and thrombin and it preferentially prolonged the clotting time in the TF-dependent extrinsic pathway.

antibiotics and constitute a significant health threat. 2‐Aminobenzimidazole derivatives (see scheme) are capable of stronglyinhibiting the growth of and dispersing Pseudomonas aeruginosa biofilms. These molecules were found to modulate quorum sensing in reporter strains, and represent some of strongest P. aeruginosa biofilm inhibitors known.
