A series of eighteen derivatives of marine sesquiterpene quinone avarone and its model system tert-butylquinone with amino acids has been synthesized by nucleophilic addition of amino acids to the quinones. In vitro cytotoxic activity toward human cancer cell lines (HeLa, A549, Fem-X, K562, MDA-MB-453) and normal MRC-5 cell line was determined. Several compounds showed very strong inhibitory activity
通过将氨基酸亲核加成到醌中,合成了十八种海洋倍半萜醌阿瓦隆及其模型体系叔丁基醌与氨基酸的衍生物。确定了对人癌细胞系(HeLa,A549,Fem-X,K562,MDA-MB-453)和正常MRC-5细胞系的体外细胞毒活性。几种化合物表现出非常强的抑制活性,IC 50值小于10μM。Avarone衍生物比相应的更活跃叔-丁基醌衍生物。HeLa细胞周期的细胞荧光分析结果表明,凋亡可能是这些化合物在癌细胞中起作用的可能机制之一。为了检查胱天蛋白酶对细胞死亡的影响,使用特定的胱天蛋白酶3、8和9抑制剂确定了由测试化合物诱导的凋亡机制。对于所有化合物,确定了对六株革兰氏阳性菌和四株革兰氏阴性菌的抗菌活性,以及对三种真菌种类的抗真菌活性。
