  This invention discloses 2α-methyl and 2β-methyl analogs of 19,26-dinor-1α,25-dihydroxyvitamin D 3 and pharmaceutical uses therefor. These compounds exhibit in vitro biological activities 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. These compounds have little, if any, in vivo calcemic activity and therefore may be used to treat autoimmune disorders in humans as well as secondary hyperparathyroidism and renal osteodystrophy.

  This invention discloses 2-methylene-(20S,25S)-19,26-dinor-vitamin D analogs, and specifically 2-methylene-(20S,25S)-19,26-dinor-1α,25-dihydroxyvitamin D 3 , and pharmaceutical uses therefor. This compound exhibits 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 has little, if any, calcemic activity 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.

• Removal of the 26-Methyl Group from 19-nor-1α,25-Dihydroxyvitamin D₃ Markedly Reduces in Vivo Calcemic Activity without Altering in Vitro VDR Binding, HL-60 Cell Differentiation, and Transcription

  Twelve new analogues of 19-nor-1 alpha,25-dihydroxyvitamin D-3 (5-16) were prepared by convergent syntheses, employing the Wittig-Horner reaction. The necessary Grundmann type ketones (45-48), possessing fixed configurations of the hydroxyl group at C-25, were obtained by a multistep procedure from commercial vitamin D-2 and enantiomers of 1,3-butanediol (23 and 24). We have examined the influence of removal of one of the methyl groups located at C-25 on the biological in vitro and in vivo activity. The in vivo tests showed that the synthesized vitamin D compounds (5-16) exhibit reduced calcemic activity both in bone and in the intestine. However, in vitro potency of 2-methylene and 2 alpha-methyl compounds (5-10, 13, and 14) remained similar or enhanced as compared to that of 1 alpha,25-(OH)(2)D-3.
