6-anhydro-D-glycero-L-gluco-heptitol-1-yl]-L-serine 3 and-L-threonine 4 were synthesized, employing regio- and stereoselective aziridine ring opening methodology. They proved to be stable in the presence of glycosidases and showed competitive inhibition of alpha-galactosidase from Aspergillus niger.
作为新型糖苷酶抑制剂的潜在先导结构,新型O-糖基氨基酸模拟物3'-O- [2,6-脱水-D-甘油-L-葡萄糖-庚醇-1-基] -L-丝氨酸3通过使用区域和立体选择性氮丙啶开环方法合成了α-L和苏氨酸4。它们被证明在糖苷酶存在下是稳定的,并显示出来自黑曲霉的α-半乳糖苷酶的竞争性抑制作用。
