基于先前报道的截短d -1'-同源腺苷衍生物的多药理学特征 [ J. Med. 化学。 2020 , 63 , 16012],使用计算机辅助设计合成了L-核苷类似物并评估了生物活性。通过单甲苯磺酸酯和Mitsunobu缩合的关键分子内环化,从d-核糖合成了目标分子。L-核苷类似物2d的过氧化物酶体增殖物激活受体(PPAR)结合活性(PPARγ K i = 4.3 μM,PPARδ K i = 1.0 μM)与对照组相比显着提高d-核苷化合物1(分别为 11.9 和 2.7 μM)。此外,L-核苷显示出比D-核苷类似物更有效的脂联素分泌促进活性。
cyclization compound which gave with tosyl chloride 1,4-anhydro-2,3- O -isopropylidene-5- O -trityl- d -ribitol. The latter was transformed (acid hydrolysis, periodate oxidation, reduction, tritylation, and tosylation) into a ditosylated derivative 16 , which was cyclized into morpholines by the action of primary amines. Acid hydrolysis, followed by acetylation, gives the (2 S )-acetoxymethyl-4-isopropyltetrahydro-1
