ABSTRACT:
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.
