R-ENANTIOMER OF RIVAROXABAN

Description: 5-R-Rivaroxaban is (R)-enantiomer of Rivaroxaban (also known as BAY 59-7939) which is the first orally available, direct inhibitor of Factor Xa with Ki and IC50 of 0.4 nM and 0.7 nM in cell-free assays, respectively. Rivaroxaban binds to the Tyr288 in S1 pocket of factor Xa through the interaction of Tyr288 and the chlorine substituent of the chlorothiophene moiety. Rivaroxabanis used as an oral anticoagulant developed by Bayer amd was marketed in a number of countries with the brand name of Xarelto. Rivaroxaban is well absorbed from the gut and maximum inhibition of factor Xa occurs four hours after a dose. The effects lasts 8A–12 hours, but factor Xa activity does not return to normal within 24 hours so once-daily dosing is possible.
