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.
本研究提供了 1α,25-二羟
维生素 D3 的新型含
硫类似物。 这些类似物是通过连接 A 环和 C、D 环片段以聚合方式合成的。 每种具有 1α,3β-取代基立体
化学结构的类似物在药理学上都显示出理想的组合,即在体外具有高抗增殖活性和高转录活性,在体内具有低血
钙活性。
