Abstract
The invention provides, as novel vitamin D derivatives, analogs of vitamin D.sub.2 compounds which lack the 24-methyl substituent and are identified as 1.alpha.-hydroxy-28-norvitamin D.sub.2 and 1.alpha.,25-dihydroxy-28-norvitamin D.sub.2. The compounds of the invention are characterized by unexpectedly high vitamin D-like activity as well as a novel activity pattern. Because of such activity they would find ready application as substitutes for vitamin D or various of the known vitamin D metabolites in their various application for the treatment of calcium disorders.
