  • Vitamin D derivatives
    Patent number: 4292250
    Abstract: The invention provides new 25-hydroxy vitamin D.sub.2 25-glucuronide derivatives among which is 25-hydroxy vitamin D.sub.2 25-D-glucuronic acid.By virtue of the structural similarity of 25-hydroxy vitamin D.sub.2 25-D-glucuronic acid to 25-hydroxy vitamin D.sub.2, a known biologically potent compound, the glucuronic acid compound should be a ready substitute for 25-hydroxy vitamin D.sub.2 in various therapeutic applications and particularly where the water solubility of the glucuronic acid compound is a necessity or advantage.
