A series of 7-amino- and 7-acetamidoquinoline-5,8-diones with aryl substituents at the 2-position were synthesized, characterized, and evaluated as potential NAD(P)H:quinone oxidoreductase (NQO1) -directed antitumor agents. The synthesis of lavendamycin analogues is illustrated. Metabolism studies demonstrated that 7-amino analogues were generally better substrates for NQO1 than 7-amido analogues,
合成、表征和评估了一系列在 2 位具有芳基取代基的 7-氨基和 7-乙酰氨基喹啉-5,8-二酮,并将其评估为潜在的 NAD(P)H: 醌氧化还原酶 (NQO1) 定向抗肿瘤剂。说明了拉文霉素类似物的合成。代谢研究表明,7-氨基类似物通常是 NQO1 比 7-酰胺类似物更好的底物,在 C-2 位置具有较小杂芳族取代基的化合物也是如此。令人惊讶的是,只有两种化合物,7-acetamido-2-(8'-quinolinyl)quinoline-5,8-dione ( 11 ) 和 7-amino-2-(2-pyridinyl)quinoline-5,8-dione ( 23)),与 NQO1 缺失的 MDA468-WT 细胞相比,对表达 NQO1 的 MDA468-NQ16 乳腺癌细胞显示出选择性细胞毒性。对于所有其他化合物,NQO1 可防止喹啉-5,8-二酮细胞毒性。化合物22对表达或不表达 NQO1
