corresponding 9-methoxylated compounds. However, their antitumor efficiencies on the in vivo experimental systems do not confirm the advantage of demethylation. The presence of a [(dialkylamino)alkyl]amino side chain at the 1 position of ellipticines increases the antitumor potency: 1-[[3-(diethylamino)propyl]amino]-5,11-dimethyl-6H-pyrido[4,3-b]carbazole (5) is a very potent antitumor compound (% ILS of 134 on
据报道,基于相应的1-氯玫瑰树碱的取代,合成了一系列1-氨基取代的吡啶并[4,3-b]咔唑衍生物。描述了对体外生长的肿瘤细胞的细胞毒性特性,最有效的体外细胞毒性化合物的体内急性毒性以及对L1210白血病系统的抗肿瘤特性。在该系列中,未观察到与DNA的明显缔合常数与体外细胞毒性或体外抗肿瘤效率之间的相关性。9-羟基化衍生物在体外比相应的9-甲氧基化化合物更具细胞毒性。然而,它们在体内实验系统上的抗肿瘤效率并未证实去甲基化的优势。
