Abstract: The biological screening of a collection of nature occurring diterpenoids against 11β-HSD1 resulted in the discovery of the lead compound 1b, which pointed to the therapeutic potential for type 2 diabetes. Subsequently, an optimization project was initiated. Starting from compound 1b and its counterpart 2, the hemi-synthesis was performed on kaurenic acid scaffolds yielding 36 derivatives. Further evaluations on both human and mouse 11β-HSD revealed that seven urea derivatives exhibited significant improved potency and selectivity. Especially, the urea 19a has an IC50 (human 11β-HSD1) = 9.4 nM and selectivity index (human 11β-HSD) > 10,649. The 2D and 3D binding models of the complex 19a/11β-HSD1 were generated using docking simulations. Based on the results, the structural-activity relationships (SARs) of compounds 1b and 2 were also discussed.
