The endogenous bile acid metabolite 1β-hydroxy-deoxycholic acid (1β-OH-DCA) excreted in human urine may be used as a sensitive CYP3A biomarker in drug development reflecting in vivo CYP3A activity. An efficient and stereospecificenzymaticsynthesis of 1β-OH-DCA was developed using a Bacillus megaterium (BM3) cytochrome P450 (P450) mutant, and its structure was confirmed by nuclear magnetic resonance

unlabeled and stable isotope labeled forms was required for use as a biomarker for Cytochrome P450 3A4/5 activity. A lengthy synthesis was undertaken to deliver the unlabeled compound and in the process, to develop a route to the deuteriumlabeledcompound. The synthesis of the unlabeled compound was completed but in a very low yield. Concurrent with the synthetic approach, a biosynthetic route was pursued
