pro-inflammatory cytokines (TNF-α, IL-1β and IL-6) along with nitric oxide reduction in RAW 264.7 cells by 7,8-dihydroxy-4-methylcoumarin, ethyl p-coumarate, ethyl caffeate and ethyl ferulate drove us to search structural-analogues of the aforementioned compounds through structure-based drug design. Docking studies revealed that substituted cinnamic acids and their ethyl esters (2-7c) showed higher GoldScore-fitness
用7,8-二羟基-4-甲基香豆素,对香豆酸乙酯,咖啡酸乙酯和阿魏酸乙酯抑制RAW 264.7细胞中的促炎性细胞因子(TNF-α,IL-1β和IL-6)并减少一氧化氮我们通过基于结构的药物设计来搜索上述化合物的结构类似物。对接研究表明,取代的肉桂酸及其乙酯(2-7c)与7,8-二羟基-4-甲基香豆素(1a)和7,8-二羟基-5-甲基香豆素(1b)。在这种背景下,将甲基香豆素(1a和1b)和肉桂酸衍生物(2-7c)以不同的排列和组合方式融合,以生成60种新颖的稠合环香豆素(FCL)(8-13k)。对8-13k的对接研究表明,与标准品(粘菌素A,双氯芬酸钠和泼尼松龙)相比,几种FCL具有更高的GSF,有趣的活性位点相互作用和独特的π-π相互作用。基于这些发现,合成了四种新颖的FCL(9d,10d,11d和11e),并测试了它们对LPS和草酸盐晶体诱导的体外模型中TNF-α,IL-1β和IL-6表
