As part of an ongoing effort to apply the Deuterated Chemical Entity Platform (DCE Platform™) to clinically validated drugs, the synthesis of deuterated analogs of the hepatitis C virus protease inhibitor boceprevir was carried out. The devised synthetic routes allowed for site-selective deuterium incorporation with high levels of isotopic purity. Application of the DCE Platform™ to boceprevir enabled the identification of several deuterated analogs that display marked levels of in vitro metabolic stabilization. Most notably, analog 1g exhibits a near doubling of in vitro half-life in human liver microsomal assays. The details of the convergent synthetic route to the boceprevir isotopologs and the results of the metabolic stability assays are described herein.
