Deuterated clopidogrel analogues as a new generation of antiplatelet agents.

ABSTRACT: Clopidogrel (CPG) is an antithrombotic prodrug that needs hepatic cytochrome P450 (CYP) enzymes for its bioactivation. The clinical effects of CPG have been associated with high intersubject variability and a certain level of resistance. Recently, comprehensive biotransformation studies of CPG support that the observed clinical uncertainty stems from the low bioactivation efficiency, which is attributed to extensive attritional metabolism (e.g., hydrolysis of the methyl ester functionality and oxidation of the piperidine moiety). With the goal of potentiating the desired thiophene 2-oxidation through minimal structural modification, we have adopted the strategy of targeted metabolism shift and have designed and synthesized deuterated piperidine analogues of CPG. In vitro studies showed tha
