  名称：

  The 2α-(3-hydroxypropyl) group as an active motif in vitamin D3 analogues as agonists of the mutant vitamin D receptor (Arg274Leu)

  摘要：

  We designed and synthesized 1 alpha- and 1 beta-hydroxymethyl-2 alpha-(3-hydroxypropyl)-25-hydroxyvitamin D-3 (2a,b) and related analogues 2 alpha-(3-hydroxypropyl)-25-hydroxyvitamin D-3 (3), Posner's analogues of 1 alpha- and 1 beta-hydroxymethyl-25-hydroxyvitamin D-3 (4a,b), as well as 2 alpha-(3-hydroxypropyl)-1 alpha,25-dihydroxyvitamin D-3 (5), to confirm the effect of the 1 alpha-hydroxy group and/or 2 alpha-(3-hydroxypropyl) group of vitamin D-3 analogues with the modified A-ring moiety on the mutant vitamin D receptor, VDR(Arg274Leu). The 2 alpha-(3-hydroxypropyl) group showed better effect on enhancement of the transcriptional activity through the mutant VDR than the 1 alpha- and 1 beta-hydroxymethyl groups.
