Abstract

SAR studies on the stereoisomers of CP-470,711 suggested that in vivo epimerization was taking place in rats. Further metabolism studies revealed that no epimerization was occurring in dogs, and that no epimerization was expected in humans. A mechanism for the in vivo epimerization is proposed involving an oxidation-reduction pathway of the secondary benzylic alcohol, in contrast to an acid/base-promoted epimerization of the same center during Chemical Synthesis.
