  26- and 27-Methyl groups of 2-substituted, 19-nor-1α,25-dihydroxylated vitamin D compounds are essential for calcium mobilization in vivo

  摘要：

  Twelve new analogs of 19-nor-1 alpha,25-dihydroxyvitamin D-3 6-17, were prepared by a multi-step procedure from known alcohols 18 and 19. We have examined the influence of removing two methyl groups located at C-25, as well as the 25-hydroxy group, on the biological in vitro and in vivo biological activity. Surprisingly, removal of the 26- and 27-methyl groups from either the 2 alpha-methyl or 2-methylene-19-nor-1 alpha,25-dihydroxyvitamin D-3 reduced vitamin D receptor binding, HL-60 differentiation, and 25-hydroxylase transcription in vitro only slightly to moderately (compounds 6-13). However, these compounds were devoid of in vivo bone mobilization activity and had markedly reduced activity on intestinal calcium transport. The analogs 14-17 with a 2 beta-methyl substitution had little or no activity in vitro and in vivo as expected from previous work. (C) 2013 Elsevier Inc. All rights reserved.

  This invention discloses (20R)-2α-methyl-19,26,27-trinor-vitamin D analogs, and specifically (20R)-2α-methyl-19,26,27-trinor-1α,25-dihydroxyvitamin D 3 , and pharmaceutical uses therefor. This compound exhibits transcription activity as well as pronounced activity in arresting the proliferation of undifferentiated cells and inducing their differentiation to the monocyte thus evidencing use as an anti-cancer agent and for the treatment of skin diseases such as psoriasis as well as skin conditions such as wrinkles, slack skin, dry skin and insufficient sebum secretion. This compound also shows very low activity in vivo on bone calcium mobilization and intestinal calcium transport activity compared to the native hormone 1α,25-dihydroxyvitamin D 3 , and therefore may be used to treat autoimmune disorders or inflammatory diseases in humans as well as renal osteodystrophy. This compound may also be used for the treatment or prevention of obesity.
