7VQP - PubMed Abstract:
1α,25-Dihydroxyvitamin D 3 [1α,25(OH) 2 D 3 , 1 ] is an active form of vitamin D 3 and regulates various biological phenomena, including calcium and phosphate homeostasis, bone metabolism, and immune response via binding to and activation of vitamin D receptor (VDR). Lithocholic acid (LCA, 2 ) was identified as a second endogenous agonist of VDR, though its potency is very low. However, the lithocholic acid derivative 3 ( Dcha-20 ) is a more potent agonist than 1α,25(OH) 2 D 3 , ( 1 ), and its carboxyl group has similar interactions to the 1,3-dihydroxyl groups of 1 with amino acid residues in the VDR ligand-binding pocket. Here, we designed and synthesized amide derivatives of 3 in order to clarify the role of the carboxyl group. The synthesized amide derivatives showed HL-60 cell differentiation-inducing activity with potency that depended upon the substituent on the amide nitrogen atom. Among them, the N -cyanoamide 6 is more active than either 1 or 3 .
