This invention discloses 2-methylene-(22E)-25-(1-methylene-hexyl)-26,27-cyclo-22-dehydro-19-nor-vitamin D analogs, and specifically 2-methylene-(22E)-25-(1-methylene-hexyl)-26,27-cyclo-22-dehydro-19-nor-1α,24(R)-dihydroxyvitamin D3, and pharmaceutical uses therefor. This compound exhibits relatively high 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 lower activity in vivo on bone calcium mobilization and intestinal calcium transport activity compared to the native hormone 1α,25-dihydroxyvitamin D3, 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.
本发明揭示了2-亚甲基-(22E)-25-(1-亚甲基-己基)-26,27-环-22-去氢-19-去氢维生素D类似物,特别是2-亚甲基-(22E)-25-(1-亚甲基-己基)-26,27-环-22-去氢-19-去氢-1α,24(R)-二羟基维生素D3,以及其药物用途。该化合物表现出相对较高的转录活性,以及在阻止未分化细胞增殖和诱导它们分化为单核细胞方面表现出显著活性,因此可用作抗癌剂和治疗牛皮癣等皮肤疾病以及皮肤状况,如皱纹、松弛的皮肤、干燥的皮肤和不足的皮脂分泌。与原生激素1α,25-二羟基维生素D3相比,该化合物在体内对骨钙动员和肠钙转运活性的活性较低,因此可用于治疗人类的自身免疫性疾病或炎症性疾病以及肾性骨营养不良。该化合物还可用于治疗或预防肥胖症。
