    • 1.alpha.,25-Dihydroxy-24R-fluorocholecalciferol and 1.alpha.,25-dihydroxy-24S-fluorocholecalciferol, analogs of 1.alpha.,25-dihydroxy-cholecalciferol which is physiologically the most active metabolite of vitamin D.sub.3, are synthesized in a multistep process from the known substance 1.alpha.,3.beta.-dihydroxyandrost-5-en-17-one. The new analogs are characterized by the ability to increase intestinal calcium transport, increase serum calcium and phosphate concentrations and to increase the deposition of these minerals in bones. These compounds will find a ready application as substitutes for natural 1.alpha.,25-dihydroxycholecalciferol in the treatment of disease states characterized by metabolic calcium and phosphate deficiencies. Exemplary of such disease states are the following: osteosclerosis, anticonvulsant treatment, osteopenia, fibrogenesis-imperfecta ossium, secondary hyperparathyrodism, hypoparathyroidism, hyperparathyroidism, cirrhosis, obstructive jaundice, drug induced metabolism, medullary carcinoma, chronic renal disease, hypophosphatemic VDRR, vitamin D-dependent rickets, sarcoidosis, glucocorticoid antagonism, malabsorption syndrome, steatorrhea, tropical sprue, idiopathic hypercalcemia and milk fever.
    • 1α,25-二羟基-24R-氟代胆钙化甾醇和1α,25-二羟基-24S-氟代胆钙化醇,其是生理上是维生素D3的最活跃代谢物的1α,25-二羟基 - 胆钙化甾醇的类似物,在多步骤过程中合成, 已知物质1α,3β-二羟基雄甾-5-烯-17-酮。 新的类似物的特征在于能够增加肠钙运输,增加血清钙和磷酸盐浓度,并增加这些矿物质在骨骼中的沉积。 这些化合物将作为替代天然1α,25-二羟基胆钙化醇在治疗以代谢钙和磷酸盐缺乏为特征的疾病状态中的现成应用。 这些疾病状态的示例如下:骨硬化,抗惊厥治疗,骨质减少,纤维发生不全性骨,继发性高甲状旁腺功能亢进,甲状旁腺功能减退,甲状旁腺功能亢进,肝硬化,阻塞性黄疸,药物诱导代谢,髓质癌,慢性肾脏疾病,低磷血症VDRR,维生素D- 依赖性r r病,结节病,糖皮质激素拮抗作用,吸收不良综合征,肉芽肿,热带口炎,特发性高钙血症和牛奶热。
