and pharmaceutical uses therefor. These compounds exhibit 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. These compounds also have little, if any, calcemic activity and therefore may be used to treat autoimmune disorders or inflammatory diseases in humans as well as renal osteodystrophy. These compounds may also be used for the treatment or prevention of obesity.
本发明揭示了19,26,27-三去(20S)-1α-羟基
维生素D3的2α-
甲基和2β-
甲基类似物及其药用。这些化合物在抑制未分化细胞的增殖和诱导它们分化为单核细胞方面表现出显著活性,因此可作为抗癌剂以及用于治疗
银屑病等皮肤疾病以及皱纹、松弛皮肤、干燥皮肤和皮脂分泌不足等皮肤状况。这些化合物也几乎没有
钙代谢活性,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病。这些化合物还可用于肥胖的治疗或预防。
