nM) in liver cancer cells with IC50 values of 15.15 nM and 10.05 nM, respectively. Additionally, at a concentration of 10 nM, compounds 35 and 36 inhibited PC with inhibitory rates of 39.10% and 40.15%, respectively, exhibiting nearly identical inhibitory activity to erianin (inhibitory rate of 40.07%). Additionally, a computer simulation docking study demonstrated the basis for better interactions
基于生物等排原理,通过改变毛兰素的两个芳香环、环上的取代基以及环上的连接基,设计合成了一系列新型毛兰素类似物。该类似物在肝细胞癌细胞中作为丙酮酸羧化酶 (PC) 抑制剂进行了评估。结果发现,用氟取代羟基的化合物35和36在肝癌细胞中表现出比毛兰素更高的活性(IC 50值为17.30 nM),IC 50值分别为15.15 nM和10.05 nM。此外,在10 nM浓度下,化合物35和36对PC的抑制率分别为39.10%和40.15%,表现出与毛兰素几乎相同的抑制活性(抑制率为40.07%)。此外,计算机模拟对接研究证明了受体和配体之间更好相互作用的基础。35的氟原子不仅可以与Lys-1043(NH⋯F,2.04 Å)形成氢键,还可以与Lys-1043(3.67 Å)和Glu-1046(3.70 Å)的羰基形成氟键,由于B环弹头上的卤素的取向不同。相反, 34的氯原子只能与Lys-1043中的
