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(More)
Hapten derivatives of 25-hydroxyvitamin D(3) and 1alpha,25-dihydroxyvitamin D(3) were synthesized using the Wittig-Horner approach. Both haptens bearing a carboxylic group at the side chain that can be linked to a protein for raising antibodies of potential utility for the determination of 25-hydroxyvitamin D(3), 1alpha,25-dihydroxyvitamin D(3) and(More)
