Novel sulfur-containing analogs of 1α,25- dihydroxyvitamin D3 are provided. These analogs are synthesized in a convergent manner by joining A-ring and C,D ring fragments. Each analog with 1α,3β-substituent stereochemistry shows a pharmacologically desirable combination of high antiproliferative and high transcriptional activities in vitro and also low calcemic activity in vivo.
