short, efficient and reliable synthesis. The selective dehydrogenation of 1,2,3,4-tetrahydroquinolinylphosphine oxides and phosphine sulfides leads to the formation of corresponding phosphorus substituted quinolines. Some of the products which were prepared showed excellent activity as topoisomerase I (Top1) inhibitors. In addition, prolonged effect of the most potent compounds is maintained with the same
这项工作描述了1,2,3,4-四氢喹啉基氧化膦,膦和硫化膦的合成,以及喹啉基氧化膦和膦硫化物的合成,合成的产率很高或很高。合成路线涉及(2-膦氧化物)-,2-膦-或(2-膦-硫化物)-苯胺,醛和烯烃的多组分反应,并允许在短,有效和短时间内选择性生成两个立体异构中心。可靠的合成。1,2,3,4-四氢喹啉基氧化膦和硫化膦的选择性脱氢导致形成相应的磷取代的喹啉。所制备的一些产品显示出作为拓扑异构酶I(Top1)抑制剂的优异活性。此外,即使在酶促反应开始后3分钟后,也可以以相同的强度维持最有效化合物的延长效果。还筛选了对源自人肺腺癌(A549),人卵巢癌(SKOV03)和人胚胎肾(HEK293)的细胞系的细胞毒性作用。1,2,3,4-四氢喹啉基氧化膦6g的IC 50值为0.25±0.03μM,对A549细胞具有优异的体外活性,而1,2,3,4-四氢喹啉基膦9c的IC 50值为0.08±0.01μM和1
