The efficient synthesis of mono-substituted anthraquinones and ring fusion into anthra[2,3-d]oxazole-2-thione-5,10-dione derivatives were developed, and all the compounds were tested for their cytotoxicity against PC-3 cancer cell lines. Compounds 8, 14, 17 and 23 were selected by the NCI and 12, 17 and 19 were evaluated for topoisomerase I-mediated DNA relaxation. Among them, 17 appeared to be the
开发了单取代的蒽醌的有效合成方法和环合成蒽[2,3 - d ]恶唑-2-硫酮-5,10-二酮衍生物的环,并测试了所有化合物对PC-3癌细胞的细胞毒性线。化合物8,14,17和23是由NCI选定和12,17和19进行评价拓扑异构酶I介导的DNA松弛。其中17种似乎是该系列中活性最高的化合物,并且从针对PC-3癌细胞系的低IC 50值表明不仅显示出更高的抑制作用,而且减弱了PC-3癌细胞的生长。低微摩尔浓度的体外拓扑异构酶I介导的DNA松弛。所有测试化合物均表现出不同的细胞抑制活性和细胞毒性活性,以进一步开发潜在的抗癌药物。
