Identification of 27-nor-3 alpha, 7 alpha, 12 alpha-trihydroxycoprostan-24-one apparently derived from 3 alpha, 7 alpha, 12 alpha-trihydroxy-24-oxocoprostanoic acid, a postulated intermediate of bile acid biosynthesis.
Incubation of [27-13C]-3 alpha, 7 alpha, 12 alpha-trihydroxycoprost-24-en-26-oic acid with rat liver homogenate followed by 13C-NMR analysis of the incubation product has resulted in the identification of [26-13C]-27-nor-3 alpha, 7 alpha, 12 alpha-trihydroxycoprostan-24-one, supporting the idea that the substrate has been metabolized into 3 alpha, 7 alpha, 12 alpha-trihydroxy-24-oxocoprostan-26-oic acid CoA derivative.
