Synthesis and biological evaluation of 1α,25-dihydroxyvitamin D(3) analogues hydroxymethylated at C-26.
J Med Chem. 2011; (11): 3950-62
We designed by docking and synthesized two novel analogues of 1α,25-dihydroxyvitamin D(3) hydroxymethylated at C-26 (2 and 3). The syntheses were carried out by the convergent Wittig-Horner approach via epoxide 12a as a common key intermediate. The antiproliferative and transactivation potency of the compounds was evaluated in colon and breast cancer cell lines. The analogues showed a similar but reduced activity compared to 1,25(OH)(2)D(3). Analogue 3 was more potent than analogue 2, and in some assays it exhibited potency similar to that of the natural ligand.
