Clopidogrel is a prodrug anticoagulant with activemetabolites that irreversibly inhibit the platelet surface GPCR P2Y12 and thus inhibit platelet activation. However, gaining an understanding of patient response has been limited due to imprecise understanding of metabolite activity and stereochemistry, and a lack of acceptable analytes for quantifying in vivo metabolite formation. Methods for the
As a precondition for detailed pharmacological investigations, an efficient chemical method for the conversion of the antiplatelet drug clopidogrel into its first metabolite 2-oxoclopidogrel was developed. The one-pot procedure, which can easily be performed on a gram scale, exploits the selective borylation of a di-anionic intermediate derived from clopidogrel with subsequent oxidative workup.
New compounds, namely, (7aS,2′S)-2-oxoclopidogrel and its pharmaceutically acceptable salts thereof are disclosed for treatment or prophylaxis of thrombo-embolism and/or cardiovascular diseases.
