A conceptually new series of vitamin D(3)-like nonfluorinated and fluorinated 16-ene side chain tert-butyl sulfones 3-7 has been synthesized. Even though these novel C,D-ring side chain analogues of the hormone 1alpha,25-dihydroxyvitamin D(3) (1,1,25D(3)) lack a terminal OH group, thought previously to be essential for high biological activity, they are highly antiproliferative and, in several cases
合成了一个概念上新的系列维生素D(3)-样非氟化和氟化16烯侧链叔丁基砜3-7。即使激素1alpha,25-dihydroxyvitamin D(3)(1,1,25D(3))的这些新颖的C,D环侧链类似物都缺少一个末端OH基团,以前认为这对于高生物活性至关重要,它们具有高度的抗增殖作用,在某些情况下,其在体外具有转录活性,但在体内则希望是无血钙的。与天然1,25D(3)的25-OH基团的氢键供体功能相反,侧链砜基可能作为氢键受体与nVDR结合。
