Several 5-O-alkyl- and 5-C-alkyl-mannitol bis-phosphates were synthesized and comparatively assayed as inhibitors of fructose bis-phosphate aldolases (Fbas) from rabbit muscle (taken as surrogate model of the human enzyme) and from Trypanosoma brucei. A limited selectivity was found in several instances. Crystallographic studies confirm that the 5-O-methyl derivative binds competitively with substrate
合成了几种 5- O-烷基-和 5 - C-烷基-甘露醇二磷酸酯,并作为兔肌肉(作为人类酶的替代模型)和锥虫的果糖二磷酸醛缩酶 (Fbas) 的抑制剂进行了比较分析布氏锥虫。在几种情况下发现选择性有限。晶体学研究证实,5- O-甲基衍生物与底物竞争性结合,5- O-甲基部分更深地渗透到活性位点的浅疏水口袋中。这一观察结果可导致制备寄生虫 Fba 的选择性竞争性或不可逆抑制剂。
