Conformationally restrained analogues of ceramide containing thiouracil or uracil moieties in their polar head, substituted with an ethyl group in their 6-positions, proved to inhibit cell proliferation and induce apoptosis. A series of new thiouracil and uracil analogues of ceramide possessing several 6-alkyl- or 6-arylalkyl-substituents, were synthesized and tested as inhibitors of cell proliferation
极地头部含有巯基尿嘧啶或尿嘧啶基团的神经酰胺的构象受约束类似物在其6位上被乙基取代,被证明抑制细胞增殖并诱导凋亡。合成了一系列具有几种6-烷基或6-芳基烷基取代基的神经酰胺的一系列新硫代尿嘧啶和尿嘧啶类似物,并测试了它们是否可作为细胞增殖抑制剂。引入6-位的亲脂取代基是纯烷基(正丙基,正丁基,异丁基,新戊基)或芳基烷基(2-苯乙基)。尽管在大多数合成的化合物中均保持了显着的抗增殖活性,但它们均未显示出与6-乙基取代的对应物相比有任何改善。
