Synthesis and Evaluation of 9-Hydroxy-5-methyl- (and 5,6-dimethyl)-6H-pyrido[4,3-b]carbazole-1-N-[(dialkylamino)alkyl]carboxamides, a New Promising Series of Antitumor Olivacine Derivatives

obtained 1-carbamoylolivacine derivatives showed that 9-hydroxylated compounds displayed high cytotoxicity for cultured L1210 and colon 38 cells (IC50 range 5-10 nM) and good antitumor activity in vivo in the P388 leukemia and colon 38 models when administered by the iv route. The most active compound in these series is 9-hydroxy-5,6-dimethyl-1-[N-[2-(dimethylamino)ethyl]carbamoyl]-6H- pyrido[4,3-b]carbazole
从2-(2-氨基乙基)-6-甲氧基-1-甲基咔唑开始,通过三步法获得9-甲氧基-5-甲基-6H-吡啶并[4,3-b]咔唑-1-羧酸乙酯。该化合物及其6-甲基衍生物与(二烷基氨基)烷基胺反应,得到各种9-甲氧基-5-甲基-6H-吡啶并[4,3-b]咔唑-1-(N-取代的羧酰胺),其三溴化硼脱甲基了。相应的9-羟基-1-(N-取代的氨基甲酰基)-奥维卡因。相同的途径但从2-(2-氨基乙基)-6-甲氧基-1,4-二甲基咔唑开始,导致乙基9-甲氧基-5,11-二甲基-6H-吡啶[4,3-b]咔唑-1-通常不与胺反应的羧酸盐。它提供了在120摄氏度下回收的起始原料或在180摄氏度的钢制容器中意外脱碳乙基化所产生的9-甲氧基玫瑰树碱。对新获得的1-氨基甲酰基脂氨酸衍生物的生物学测试表明,在施用P388白血病和结肠38模型时,9-羟基化化合物对培养的L1210和结肠38细胞(IC50范围5-10 nM)
