A series of novel 2-carbo–substituted 5-oxo-5H-furo[3,2-g]chromene-6-carbaldehydes and their 6-(4-trifluoromethyl)phenylhydrazono derivatives have been prepared and evaluated for biological activity against the human acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). The most active compounds from each series were, in turn, evaluated against the following enzyme targets involved in Alzheimer’s disease, β-secretase (BACE-1) and lipoxygenase-15 (LOX-15), as well as for anti-oxidant potential. Based on the in vitro results of ChE and β-secretase inhibition, the kinetic studies were conducted to determine the mode of inhibition by these compounds. 2-(4-Methoxyphenyl)-5-oxo-5H-furo[3,2-g]chromene-6-carbaldehyde (2f), which exhibited significant inhibitory effect against all these enzymes was also evaluated for activity against the human lipoxygenase-5 (LOX-5). The experimental results were complemented with molecular docking into the active sites of these enzymes. Compound 2f was also found to be cytotoxic against the breast cancer MCF-7 cell line.
一系列新颖的2-羰基取代的5-氧代-5H-呋喃[3,2-g]色酮-6-甲醛及其6-(4-三氟甲基)苯基肼衍生物已被合成并评估其对人类乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BChE)的生物活性。每个系列中最活跃的化合物分别针对参与阿尔茨海默病的以下酶靶标进行评估,包括β-分泌酶(BACE-1)和脂氧合酶-15(LOX-15),以及抗氧化潜力。基于对ChE和β-分泌酶抑制的体外结果,进行了动力学研究以确定这些化合物的抑制方式。2-(4-甲氧基苯基)-5-氧代-5H-呋喃[3,2-g]色酮-6-甲醛(2f)对所有这些酶表现出显著的抑制效果,还评估了其对人类脂氧合酶-5(LOX-5)的活性。实验结果通过分子对接到这些酶的活性位点进行了补充。化合物2f还发现对乳腺癌MCF-7细胞系具有细胞毒性。
