The synthesis of dihydroxybenzoperimidine derivatives, which are chromophore-modified dihydroxyanthracenediones with an additional pyrimidine ring incorporated into the chromophore, is reported. These derivatives are structurally related to the antitumor agent mitoxantrone. Their synthesis was carried out by the reaction of 6-amino-8,11-dihydroxy-7H-benzo[e]perimidin-7-one (5) or 6,8, 11-trihydrox
报道了二羟基苯并亚丙基衍生物的合成,该衍生物是生色团修饰的二羟基蒽二酮,并带有一个附加的嘧啶环并入到生色团中。这些衍生物在结构上与抗肿瘤药米托蒽醌有关。它们的合成是通过6-氨基-8,11-二羟基-7H-苯并[e] perimidin-7-(5)或6,8,11-三羟基-7H-苯并[e] perimidin-进行的。 7-一(10)与许多各自的(烷基氨基)烷基胺。二羟基苯并perimidine衍生物对小鼠白血病L1210和人白血病HL60细胞系表现出与米托蒽醌相当的体外细胞毒活性。这些化合物还针对具有MDR表型的人类MDR型耐药白血病K562R细胞系表现出一系列体外活性。该系列中活性最高的化合物 即6a,对一组人类细胞系表现出有效的体外细胞毒性活性。此外,与米托蒽醌和阿霉素相比,它在以MDR表型为特征的细胞系中显示出很小的交叉抗性。敏感的HT-29和耐米托蒽醌的HT-29 / Mx(未确定耐药
