Demethylthio-, S-demethyl-, and S-ethyl derivatives of the α-mannosidase inhibitor, mannostasin A, were synthesized and evaluated for their inhibition of Jack bean α-mannosidase with the prime objective of elucidating the role of the methylthio group. All methylthio derivatives had significantly lowered inhibitory potentials. However, one mannostatin A analogue with a methoxyl instead of the methylthio
合成了 α-甘露糖苷酶抑制剂甘露糖苷 A 的脱甲硫基、S-脱甲基和 S-乙基衍生物,并评估了它们对杰克豆 α-甘露糖苷酶的抑制作用,主要目的是阐明甲硫基的作用。所有甲硫基衍生物都显着降低了抑制潜力。然而,一种带有甲氧基而不是甲硫基的甘露糖抑素 A 类似物表现出大约两倍的活性增强。根据我们的结果讨论了甘露糖抑素 A 和相关化合物的结构和抑制活性关系。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
