N-dimethylamino)ethyl-8,9-dimethoxy-2,3-methylenedioxy-5H-dibenzo[c,h][1,6 ]naphthyridin-6-one (ARC-111, topovale) prompted studies on similarly substituted benzo[i]phenanthridine-12-carboxylic ester and amide derivatives. Among the benzo[i]phenanthridine-12-carboxylic esters evaluated, the 2-(N,N-dimethylamino)ethyl, 2-(N,N-dimethylamino)-1-methylethyl, and 2-(N,N-dimethylamino)-1,1-dimethylethyl esters
5-(2-N,N-二甲基氨基)乙基-8,9-二甲氧基-2,3-亚甲基二氧基-5H-二苯并[c,h] [1,6]萘啶的异常拓扑异构酶I靶向活性和抗肿瘤活性-6-一(ARC-111,topovale)促进了对类似取代的苯并[i]菲啶-12-羧酸酯和酰胺衍生物的研究。在所评估的苯并[i]菲啶-12-羧酸酯中,2-(N,N-二甲基氨基)乙基,2-(N,N-二甲基氨基)-1-甲基乙基和2-(N,N-二甲基氨基) -1,1-二甲基乙基酯在RPMI8402和KB3-1细胞中具有相似的细胞毒性,范围从30到55 nM。几种羧酰胺衍生物具有有效的拓扑异构酶I靶向活性和细胞毒性。2-(N,N-二甲基氨基)乙基,2-(N,N-二乙基氨基)乙基和2-(吡咯烷基-1-基)乙基酰胺是更具细胞毒性的苯并[i]菲啶-12-羧酸衍生物,
