Abstract

The synthesis of a series of imidazole styrylindoles and sulfonyl styrylindoles derivatives is described. Evaluation of binding affinity and inhibitory activity against CYP24A1 identified the imidazole styrylindoles as potent inhibitors with activity greater or comparable with the standard ketoconazole. Flexible alignment and docking studies of the inhibitors in the CYP24A1 enzyme active site confirmed that complete occupation of the vitamin D access tunnel is essential to inhibitory activity, allowing exposure to multiple hydrophobic binding interactions and optimal conformation for the interaction of the imidazole nitrogen lone pair and the active site haem.
