== Disease ==
[[http://www.uniprot.org/uniprot/DHI1_HUMAN DHI1_HUMAN]] Defects in HSD11B1 are a cause of cortisone reductase deficiency (CRD) [MIM:[http://omim.org/entry/604931 604931]]. In CRD, activation of cortisone to cortisol does not occur, resulting in adrenocorticotropin-mediated androgen excess and a phenotype resembling polycystic ovary syndrome (PCOS).

11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) catalyzes the NADPH dependent interconversion of inactive cortisone to active cortisol. Excess 11beta-HSD1 or cortisol leads to insulin resistance and metabolic syndrome in animal models and in humans. Inhibiting 11beta-HSD1 activity signifies a promising therapeutic strategy in the treatment of Type 2 diabetes and related diseases. Herein, we report two highly potent and selective small molecule inhibitors of human 11beta-HSD1. While compound 1, a sulfonamide, functions as a simple substrate competitive inhibitor, compound 2, a triazole, shows the kinetic profile of a mixed inhibitor. Co-crystal structures reveal that both compounds occupy the 11beta-HSD1 catalytic site, but present distinct molecular interactions with the protein. Strikingly, compound 2 interacts much closer to the cofactor NADP+ and likely modifies its binding. Together, the structural and kinetic analyses demonstrate two distinctive molecular inhibition mechanisms, providing valuable information for future inhibitor design.
