All eight of the major active metabolites of (S)-2-(1S,2S,4R)-bicyclo [2.2.1]heptan-2-ylamino)-5-isopropyl-5-methylthiazol-4(5H)-one (AMG 221, compound 1), an inhibitor of 11 beta-hydroxysteroid dehydrogenase type 1 that has entered the clinic for the treatment of type 2 diabetes, were synthetically prepared and confirmed by comparison with samples generated in liver microsomes. After further profiling, we determined that metabolite 2 was equipotent to 1 on human 11 beta-HSD1 and had lower in vivo clearance and higher bioavailability in rat and mouse. Compound 2 was advanced into a pharmacodynamic model in mouse where it inhibited adipose 11 beta-HSD1 activity.
