A series of structurally simple analogues of natural topopyrone C were synthesized and tested for cytotoxic and topoisomerase I inhibitory activities. The removal of the hydroxyl groups at the 5 and 9 positions resulted in an increased cytotoxic potency and ability to stabilize topoisomerase-mediated cleavage. In addition, the results suggest that some structural features, such as the pyrone ring and
合成了一系列天然拓朴酮C的结构简单的类似物,并测试了其对细胞毒性和拓扑异构酶I的抑制活性。在5和9位上羟基的去除导致增加的细胞毒性效力和稳定拓扑异构酶介导的裂解的能力。另外,结果表明某些结构特征,例如吡喃环和11位的极性基团是拓扑异构酶I抑制作用的基础。这些结构要求也与细胞毒性活性一致。
