    摘要:
    已经制备了一系列的4-取代的喹唑啉和相关化合物,并评估了它们在磷脂酶C-γ1衍生的底物上抑制表皮生长因子受体的酪氨酸激酶活性的能力。结果表明基本环系统的结构-活性关系(SAR)狭窄,喹唑啉是优选的生色团,苄基氨基和苯胺基是优选的侧链。在4-苯胺基系列中,苯环的3-位被小的亲脂性吸电子基团取代提供了具有增强效价的类似物。研究了两个系列的化合物[4-(苯甲基)氨基和4-(3-溴苯基)氨基],以确定喹唑啉取代基的SAR。在更具活性的4-(3-溴苯基)氨基系列中,给电子基团(NH2,OMe)在6或7位的活性增加,其模式与对喹唑啉环的8位附近的高电子密度的要求一致。6,7-二甲氧基衍生物是这两个系列中最有效的,而4-(3-溴苯基)氨基衍生物(3)的IC50为0.029 nM,是迄今为止最有效的酪氨酸激酶活性抑制剂。表皮生长因子受体酶的作用。

    A series of isomeric 4-[[3-(dimethylamino)propyl]amino]nitroquinolines has been synthesized and evaluated as hypoxia-selective cytotoxins and as radioeensitizers of hypoxic cells. The compounds showed widely-differing hypersensitivity factors (ratios of cytotoxicity against wild-type and repair-deficient mammalian cells). Many compounds showed oxygen-sensitive bioreduction resulting in DNA alkylation, while others show oxygen-insensitive modes of action. Of the nitro isomers studied, the 5-nitro showed the greatest hypoxic selectivity. A series of ring-substituted analogues were then prepared, in an effort to lower its reduction potential of -286 mV. Structure-activity studies showed that the effects of substitution on reduction potential were complex, being mediated by electronic and steric effects on the nitro group, as well as by effects on quinoline pK(a). Two compounds of lower reduction potential, the 3- and 8-methyl analogues, showed improved selectivity (47- and 60-fold in a clonogenic assay). These two compounds also showed the highest ''in vitro therapeutic indices'' of the series as hypoxic cell radiosensitizers. Despite these favorable in vitro properties, neither compound had activity against hypoxic cells in SCCVII tumors when administered at 60% of the MTD.
