In addition to the first synthesis of the natural bromophenol butyl 2-(3,5-dibromo-4-hydroxyphenyl)acetate (1), indene derivatives 34 and 35 were synthesized from 3-phenylpropenal derivatives in BBr3 medium. Five known natural bromophenols and some derivatives were synthesized by known methods. Cholinesterase (ChEs) inhibitors reduce the breakdown of acetylcholine and are used in the treatment of Alzheimer's
除了首次合成天然溴苯酚2-(3,5-二溴-4-羟基苯基)乙酸丁酯( 1 )之外,还在BBr 3介质中由3-苯基丙烯醛衍生物合成了茚衍生物34和35。通过已知方法合成了五种已知的天然溴苯酚和一些衍生物。胆碱酯酶 (ChEs) 抑制剂可减少乙酰胆碱的分解,用于治疗阿尔茨海默病 (AD) 和痴呆症状。检测了所有获得的化合物对乙酰胆碱酯酶(AChE)、丁酰胆碱酯酶(BChE)和α-糖苷酶的抑制作用。所有合成的化合物均表现出对两种胆碱能酶的强烈抑制作用。为了测定新型溴酚的 Ki 值,获得了 Lineweaver-Burk 图。AChE 的 Ki 值范围为 0.13–14.74 nM,BChE 的 Ki 值范围为 5.11–23.95 nM,α-糖苷酶的 Ki 值范围为 63.96–206.78 nM。与阳性对照相比,所有溴酚及其衍生物均表现出有效的抑制特性。
