    摘要: The invention provides a new derivative of vitamin D.sub.3, 24-fluoro-25-hydroxycholecalciferol.The compound is characterized by vitamin D-like activity in its ability to increase intestinal calcium transport, increase serum calcium and inorganic phosphorous concentration and to prevent the development of rickets. It would find ready application as a substitute for vitamin D.sub.3 and in the treatment of disease states evincing calcium-phosphorous imbalance and which are nonresponsive to vitamin D.sub.3 therapy.

    摘要: The invention provides new derivatives of vitamin D, 24,24-difluoro-1.alpha.,25-dihydroxycholecalciferol and 24,24-difluoro-1.alpha.,25-dihydroxy-5,6-trans-cholecalciferol and processes for preparing the same.The compounds are characterized by vitamin D-like activity essentially equivalent to the vitamin D-like activity of 1.alpha.,25-dihydrocholecalciferol which is considered to be the hormonal form and most active derivative of vitamin D. The compounds of this invention are characterized by their ability to increase intestinal calcium transport, increase serum calcium and to prevent the development of rickets. These compounds would find ready application as a substitute for vitamin D and in the treatment of disease states evincing metabolic calcium and phosphorus deficiencies.

    摘要: The invention provides a new derivative of vitamin D.sub.3, 26,26,26,27,27-pentafluoro-1.alpha.-hydroxy-27-methoxy-cholecalciferol and a process for preparing the same.The compound is characterized by some vitamin D-like activity except that it exhibits negligible activity in mobilizing bone. This characteristic indicates that the compound would find ready application in the treatment of disease or physiological states which evince loss of bone mass and application in other situations where metabolic calcium imbalances are found.

    摘要: The invention provides new derivatives of vitamin D, 23,23-difluoro-25-hydroxycholecalciferol and the acylates thereof, a method for preparing said compounds and various new intermediates utilized in such process.The derivative compounds are characterized by vitamin D-like activity as evidenced by their ability to increase intestinal calcium transport and serum calcium. The compounds are further characterized by resistance to hydroxylation at C-23, which is recognized as an essential metabolic step to the inactivation of vitamin D. The compounds should, therefore, provide vitamin D-like activity of greater time duration.
