we report the synthesis and biological evaluation of symmetric and asymmetric analogues of the DNA intercalating drug mitoxantrone (MTX) in which the side chains of the parent drug were modified through glycosylation or methyl etherification. Several analogues with glycosylated side chains exhibited higher DNA affinity than the parent MTX. The most potent in vitro cytotoxicity was observed for MTX analogue
本文中,我们报告了DNA嵌入药物米托蒽醌(MTX)的对称和不对称类似物的合成和生物学评估,其中母体药物的侧链通过糖基化或甲基醚化进行了修饰。具有糖基化侧链的几种类似物显示出比亲本MTX更高的DNA亲和力。对于带有侧链的甲氧基醚的MTX类似物8(1,4-二甲氧基-5,8-双[2-(2-甲氧基乙基氨基)乙基氨基]蒽-9,10-二酮),观察到最强的体外细胞毒性。与未经治疗的小鼠相比,用MTX或类似物8治疗荷黑素瘤小鼠可降低腹膜内肿瘤负荷。8的效果不如MTX明显。MTX与兔肝S9馏分的体外代谢测定产生了几种代谢物。几乎没有代谢产物被检测为MTX类似物8。给出的结果表明,MTX侧链伯羟基的衍生化可导致DNA亲和力的显着改善,并降低形成潜在毒性代谢物的敏感性。
