    • This invention discloses 2-methylene-20(21)-dehydro-19,24,25,26,27-pentanor-vitamin D analogs, and specifically 2-methylene-20(21)-dehydro-19,24,25,26,27-pentanor-1α-hydroxyvitamin 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 lower in vivo intestinal calcium transport activity as 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 secondary hyperparathyroidism and renal osteodystrophy. This compound may also be used for the treatment or prevention of obesity.
    • 本发明公开了2-亚甲基-20(21) - 脱氢-19,24,25,26,27-戊醇维生素D类似物,特别是2-亚甲基-20(21) - 脱氢-19,24,25,26 ,27-戊酰-1α-羟基维生素D3及其药学用途。 该化合物显示相对较高的转录活性以及阻止未分化细胞增殖并诱导其分化为单核细胞的明显活性,从而证明其用作抗癌剂并用于治疗皮肤疾病如牛皮癣以及皮肤病症 如皱纹,皮肤松弛,皮肤干燥和皮脂分泌不足。 与天然激素1α,25-二羟基维生素D 3相比,该化合物在骨钙动员和体内肠内钙转运活性方面的体内活性也较低,因此可用于治疗人的自身免疫性疾病或炎症性疾病 继发性甲状旁腺功能亢进和肾性骨营养不良。 该化合物也可用于治疗或预防肥胖症。
