Abstract

Three new Vitamin D analogs 3-5 incorporating a -CHF(2) group as an -OH surrogate have been prepared. Two of these new analogs (3 and 5) are strongly antiproliferative toward murine keratinocytes and are approximately 50 times less calciuric in vivo than the natural hormone calcitriol. The transcriptional activity of the 25-CHF(2) analog 3 is higher than that of the 1-CHF(2) analog 4.

摘要

已经制备了三种新的维生素D类似物3-5,它们引入了-CHF(2)基团作为-OH替代物。其中两种新类似物(3和5)对小鼠角质形成细胞具有强烈的抗增殖作用,并且在体内的钙尿活性比天然激素骨化三醇低约50倍。25-CHF(2)类似物3的转录活性高于1-CHF(2)类似物4。
