首次合成了C15-取代的1α,25-二羟基维生素D3类似物,以研究修饰的CD环对维生素D受体(VDR)螺旋-3和螺旋-12激动定位的生物活性的影响。X射线共晶分析证明,0.6的CD-环的位移和收缩的侧链是必要的,以保持25-羟基基团的位置与螺旋-12适当的相互作用。15-羟基-16-烯衍生物显示出比天然激素更高的hVDR结合亲和力。
C15-Substituted 1α,25-dihydroxyvitamin D3analogs were synthesized for the first time to investigate the effects of the modified CD-ring on biological activity concerning the agonistic positioning of helix-3 and helix-12 of the vitamin D receptor (VDR). X-ray cocrystallographic analysis proved that 0.6 Å shifts of the CD-ring and shrinking of the side chain were necessary to maintain the position of the 25-hydroxy group for proper interaction with helix-12. The 15-hydroxy-16-ene derivative showed higher binding affinity for hVDR than the natural hormone.
