Fluoro analogs of bioactive oxy-sterols: Synthesis of an EBI2 agonist with enhanced metabolic stability

Synthesis of several 7-hydroxy oxysterols and their potential roles as signaling molecules in the innate and adaptive immune responses is discussed. Discovery of a new, fluorinated, synthetic analog of the 7α,25-dihydroxycholesterol—the endogenous ligand of GPR 183 (EBI2), a G-protein coupled receptor highly expressed upon Epstein–Barr virus infection is described. Fluoro oxysterol 12 showed good metabolic stability while maintaining excellent EBI2 agonist activity.

Synthesis of 7alpha-hydroxy derivatives of regulatory oxysterols.

7alpha-Hydroxy derivatives of oxysterols are of considerable interest because of their possible involvement in regulation of cholesterol metabolism. This paper describes stereoselective syntheses and complete characterization of the 7alpha-hydroxy derivatives of four key oxysterols: 25-hydroxycholesterol, 27-hydroxycholesterol, 24(S)-hydroxycholesterol, and 24(S), 25-epoxycholesterol.

Blocked cholecalciferol and dihydrotachysterol 3 derivatives

Novel cholecalciferol and dihydrotachysterol3 derivatives produced against metabolic conversions at the 25-position, their preparation, pharmaceutical compositions, methods of treating steroid-induced osteoporosis, senile osteoporosis and secondary hyperparathyroidism, especially that induced by an insufficient amount of calcium in relationship to the amount of phosphate, novel intermediates and their preparation are disclosed.
