Abstract

Inhibition of 11β-HSD1 is viewed as a potential target for the treatment of obesity and other elements of the metabolic syndrome. We report here the optimisation of a carboxylic acid class of inhibitors from AZD4017 (1) to the development candidate AZD6925 (11). A central aim of this optimisation campaign was the modulation of clearance mechanism to reduce the extent of acyl glucuronidation. This was achieved by modulation of the acid substructure together with a redistribution of lipophilicity in order to achieve the desired profile.
