  • Vitamin D analogues of pharmaceutical interest
    Patent number: 9663429
    Abstract: The present invention relates to compounds of pharmaceutical interest. More particularly, it relates to compounds of formula (I), to processes for obtaining thereof, to the intermediates of their synthesis and processes for obtaining the latter. The compounds of formula (I) have a certain affinity with the vitamin D receptor, they are active in a similar order to 1,25?-dihydroxyvitamin D3 (1,25D), with the advantage of producing less or no hypercalcemia.
    Type: Grant

  • DEUTERATED VITAMIN D COMPOUNDS
    Publication number: 20110213168
    Abstract: The invention relates to deuterated vitamin D compounds and the process for preparing and synthesizing a class of vitamin D compounds which can be isotopically substituted. These compounds can be used as internal standards in methods for the quantification of vitamin D, its metabolites and analogues by mass spectrometry. These compounds are described by means of general formula I.
