methyl {(3S,5S)-5-[({4'-[N-(methoxycarbonyl)carbamimidoyl]([1,1'-biphenyl]-4-yl)}oxy)methyl]-2-oxopyrrolidin-3-yl}acetate
Lefradafiban is a member of the class of pyrrolidin-2-ones that is pyrrolidin-2-one in which the 3-pro-S-hydrogen is substituted by a 2-methoxy-2-oxoethyl group, while the 5-pro-S-hydrogen is substituted by a ({4'-[N-(methoxycarbonyl)carbamimidoyl]biphenyl-4-yl}oxy)methyl group. It is an orally active prodrug of fradafiban, a figrinogen receptor antagonist. It has a role as a prodrug and a platelet glycoprotein-IIb/IIIa receptor antagonist. It is a member of pyrrolidin-2-ones and a methyl ester. It is functionally related to a fradafiban.
