respectively. The 8-MOP analogs 19 and 24, incorporating at position 5 of the psoralen nucleus a butyl acrylate or a tert-butyl cinnamate moiety, were the most powerful inhibitors of soybean LOX and inhibited effectively lipid peroxidation. Analog 19 was a more potent anti-inflammatory agent than the reference compound indomethacin and of comparable cytocompatibility to 8-MOP whereas analog 24 was a weaker
合成了一系列适合于结构抗氧化/抗炎活性关系研究的5-和8-甲氧基补骨脂素(MOP)类似物,使用N-溴糖精对MOP进行选择性单溴化,并利用Heck反应或Suzuki偶联或Suzuki偶联,然后进行Wittig反应以分别安装丙烯酸酯或苯甲酸酯或肉桂酸酯类型的侧链。在补骨脂素核的5位掺入丙烯酸丁酯或肉桂酸叔丁酯部分的8-MOP类似物19和24是大豆LOX的最有效抑制剂,可有效抑制脂质过氧化。模拟19与消炎痛相比,消炎痛是一种比参考化合物消炎痛更有效的抗炎药,并且与8-MOP具有相当的细胞相容性,而与消炎痛相比,类似物24的消炎抑制剂弱,并且与8-MOP相比,其细胞毒性明显更高。根据结构特征讨论了生物学测试的结果。
