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.
这项发明揭示了19,26-去甲基-1α,25-二羟基
维生素D3的2α-甲基和2β-甲基类似物以及其药用。这些化合物在体外表现出
生物活性,可作为抗癌剂以及治疗
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的用途。这些化合物在体内几乎没有
钙调节活性,因此可用于治疗人类的自身免疫性疾病,以及继发性甲状旁腺功能亢进和肾性骨病。
