New 2-[2'-(dimethylamino)ethyl]-3H-dibenz[de,h]isoquinoline-1,3-diones with substituents at the 6- and 7-positions were prepared. Nucleophilic aromatic displacement was a key reaction in the syntheses. Ten of the new compounds were more potent than the unsubstituted compound, azonafide, in a panel of tumor cells including human melanoma and ovarian cancer and murine sensitive and MDR L1210 leukemia
制备了在6-和7-位具有取代基的新的2- [2'-(二甲基氨基)乙基] -3H-二苯并[de,h]异喹啉-1,3-二酮。亲核芳香族取代是合成中的关键反应。在包括人类黑素瘤和卵巢癌以及鼠类敏感和MDR L1210白血病在内的一系列肿瘤细胞中,十种新化合物比未取代的化合物azonafide更有效。它们在细胞培养中的心脏毒性也较小。这些化合物中的四种对MDR白血病不具有交叉耐药性,其中一种(6-乙氧基氮磺酰胺)对实体瘤细胞的效力几乎与白血病细胞一样。这些化合物对人乳腺癌,结肠癌和肺癌细胞(包括阿霉素和米托蒽醌抗性细胞株)也具有良好的效力。与阿佐那非相比,新类似物在体内的优势更小,但是6-乙氧基氮芥酸对小鼠的L1210白血病和皮下B16黑色素瘤更有效。尽管未发现细胞中抗肿瘤效力与取代基的理化性质之间的相关性,但在统计学上,DNA熔融转变温度(δTm)与实体肿瘤细胞以及对6取代的azonafides
