Structure based drug design: Development of potent and selective factor IXa (FIXa) inhibitor

Article abstract of DOI:10.1021/jm901476x

On the basis of our understanding on the binding interactions of the benzothiophene template within the FIXa active site by X-ray crystallography and molecular modeling studies, we developed our SAR strategy by targeting the 4-position of the template to access the S1 β and S2-S4 sites. A number of highly selective and potent, factor Xa (FXa) and FIXa inhibitors were identified by simple switch of functional groups with conformational changes toward the S2-S4 sites.
