study of substituted 2-phenyl-4-quinolones and flavonoids as antitumor and antiviral agents, a series of 5,6,7,8-substituted-2-phenylthiochromen-4-ones has been synthesized by condensation of substituted thiophenols and ethyl benzoylacetates. Target compounds were evaluated for biological activity. Among them, compounds 7, 10, 12, and 13 displayed significant growth inhibitory action against a panel
作为我们对取代的2-苯基-4-喹诺酮和类黄酮作为抗肿瘤剂和抗病毒剂的结构-活性关系研究的延续,已经开发了一系列5,6,7,8-取代的-2-苯基硫代色素n-4-酮通过取代的苯硫酚与苯甲酰乙酸乙酯的缩合反应合成。评价目标化合物的生物活性。其中,化合物7、10、12和13对一组肿瘤细胞系表现出显着的生长抑制作用,这些细胞系包括人回盲癌(HCT-8),鼠白血病(P-388),人黑素瘤(RPMI)和人中枢神经系统肿瘤(TE671)细胞。化合物10、12和19在体外显示出DNA拓扑异构酶I的抑制活性,化合物11在体外是DNA拓扑异构酶II的抑制剂。化合物11的活性最高(ED50值为0。
