4-diaryl-5,6-dihydrothieno[2,3-h] quinoline derivatives as rigid analogs of 2,4,6-trisubstituted pyridines were evaluated for topoisomerase I and II inhibitory activities as well as cytotoxicities against several human cancer cell lines. Structure–activity relationship study showed that [2,2′;6′,2″]-terpyridine skeleton is important for the cytotoxicity against several human cancer cell lines.
设计并合成了32个2,4,2-二芳基-5,6-二氢-1,10-菲咯啉和2,4-二芳基-5,6-二氢噻吩并[2,3- h ]喹啉衍生物作为2的刚性类似物评价了4,6-三取代的吡啶对拓扑异构酶I和II的抑制活性以及对几种人类癌细胞系的细胞毒性。结构-活性关系研究表明,[2,2'; 6',2'']-吡啶吡啶骨架对几种人类癌细胞系的细胞毒性具有重要作用。
