Vitamin D analogues

Group of chemical compounds


Group of chemical compounds

The natural, active form of vitamin D is calcitriol (1,25-dihydroxycholecalciferol). This molecule and other naturally occurring forms of vitamin D, including its precursors and metabolites, have been modified to synthesize pharmaceuticals with potentially greater, or selective, therapeutic actions.

Types

These include:

  • Alfacalcidol
  • Calcipotriol (calcipotriene)
  • Doxercalciferol
  • Falecalcitriol
  • Paricalcitol
  • Tacalcitol

Mechanisms

These modified vitamin D analogues have a side chain or other modifications. They aim to reduce the classical renal and intestinal effects of calcitriol on calcium and phosphate homeostasis, from its effects on other biologic processes. They target cell proliferation and differentiation, especially in skin, or other effects in the parathyroid gland (secondary hyperparathyroidism) or bone cells.
