| Research Abstract |
Vitamin D receptor (VDR) belongs to the steroid/thyroid hormone nuclear receptor superfamily. The X-ray crystal structure of the ligand binding domain (LBD) of VDR with 1α,25-dihydroxyvitamin D_3 was determined by Moras et al. in 2000 and the binding mode between ligands and LBD-VDR was revealed.
Hereditary vitamin D-resistant rickets (HVDRR) is a genetic disorder caused by mutations in the vitamin D receptor, which lead to resistance to 1α,25-dihydroxyvitamin D_3 [1α,25(OH)_2D_3]. We found that the A ring-modified analogues, 2α-(3-hydroxypropyl)-and 2α-(3-hydroxypropoxy)-1α,25(OH)_2D_3, (O1C3 and O2C3) can bind better than the natural hormone to the mutant VDR (R274A), which similar to the HVDRR mutant, R274L, had lost the hydrogen bond to the 1α-hydroxyl group of 1α,25(OH)_2D_3. We have also studied on docking models.
