Abstract: Novel 2alpha-substituted 1alpha,25-dihydroxyvitamin D3 analogues were efficiently synthesized and their biological activities were evaluated. 2alpha-Methyl-1alpha,25-dihydroxyvitamin D3 (2), whose unique biological activities were previously reported, was modified to 2alpha-alkyl (ethyl and propyl) and 2alpha-hydroxyalkyl (hydroxymethyl, hydroxyethyl, and hydroxypropyl) analogues 3-7 by elongation of the alkyl chain and/or introduction of a terminal hydroxyl group. 2alpha-Hydroxypropyl-1alpha,25-dihydroxyvitamin D3 (7) exhibited an exceptionally potent calcium-regulating effect and a unique activity profile.
