Cinnamic anhydrides have been shown to be more than reactive reagents, but they also act as inhibitors of the enzyme acetylcholinesterease (AChE). Thus, out of a set of 33 synthesised derivatives, several of them were mixed type inhibitors for AChE (from electric eel). Thus, (E)-3-(2,4-dimethoxyphenyl)acrylic anhydride (2c) showed Ki = 8.30 ± 0.94 µM and Ki' = 9.54 ± 0.38 µM, and for (E)-3-(3-chlorophenyl)acrylic
肉桂酸酐已被证明比反应性试剂更重要,但它们也可作为乙酰胆碱酯酶(AChE)的抑制剂。因此,在一组33种合成衍生物中,其中几种是AChE的混合型抑制剂(来自鳗鱼)。因此,对于(E)-3-(3-氯苯基)丙烯酸,(E)-3-(2,4-二甲氧基苯基)丙烯酸酐(2c)的Ki = 8.30±0.94μM,Ki’= 9.54±0.38μM。酸酐(2u)的Ki = 8.23±0.93 µM,Ki'= 13.07±0.46 µM。这些化合物虽然对许多人类细胞系无细胞毒性,但它们对AChE却表现出前所未有的且值得注意的抑制作用,但对丁酰胆碱酯酶(BChE)却没有。
