The synthesis and biological activities of representatives of a new class of antitumor agent, the N-[2-(dialkylamino)ethyl ]-9-aminoacridine-4-carboxamides, are reported. Members of this class are stable and very water soluble with high levels of in vitro and in vivo antitumor activity. The compounds bind tightly to double-stranded DNA by intercalation, but the requirements for antitumor activity are
报道了新型抗肿瘤剂N- [2-(二烷基氨基)乙基] -9-氨基ac啶-4-羧酰胺的代表的合成和生物学活性。这类成员是稳定的并且非常易溶于水,具有高水平的体外和体内抗肿瘤活性。这些化合物通过插入与双链DNA紧密结合,但对抗肿瘤活性的要求更为严格。它们主要取决于两个阳离子中心的分离距离,位置和pKa值。对于体内活性,对于C-9 a啶位置附近的亲脂性但不存在亲水性基团以及侧链阳离子部分上的亲脂性和亲水性基团存在显着的体积耐受性。侧链阳离子中心pKa的显着减弱消除了活性,
