Removal of the 26-methyl group from 19-nor-1α,25-dihydroxyvitamin D(3) markedly reduces in vivo calcemic activity without altering in vitro VDR binding, HL-60 cell differentiation and transcription

Twelve new analogs of 19-nor-1α,25-dihydroxyvitamin D(3) (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 and 16), were prepared by convergent syntheses, employing the Wittig-Horner reaction. The necessary Grundmann-type ketones (45, 46, 47 and 48), possessing fixed configurations of the hydroxyl group at C-2...
