  摘要：

  已经合成了一系列取代的2-苯基苯并咪唑-4-羧酰胺，并评估了其体外和体内抗肿瘤活性。这些化合物代表了我们寻找具有最低可能的DNA结合常数的“最小” DNA嵌入剂的逻辑结论。具有比结构相似的2-苯基喹啉更低的芳香性的这种“ 2-1”三环发色团具有迄今为止在广泛的三环羧酰胺嵌入剂系列中所见的最低的DNA结合亲和力。尽管体外细胞毒性非常低，但是其中一些化合物具有中等水平的体内抗白血病作用。但是，其生物学活性最有趣的方面是，对耐氨曲林的P388细胞株缺乏交叉耐药性，

  Synthesis and SAR of novel di- and trisubstituted 1,4-dihydroquinoxaline-2,3-diones related to licostinel (Acea 1021) as NMDA/glycine site antagonists

  摘要：

  A series of novel di- and trisubstituted 1,4-dihydroquinoxaline-2,3-diones (QXs) related to licostinel (Acea 1021) was synthesized and evaluated as antagonists for the glycine site of the N-methyl-D-asparate (NMDA) receptor. The in vitro potency of these antagonists was determined by displacement of the glycine site radioligand [H-3]-5,7-dichlorokynurenic acid ([H-3]DCKA) in rat brain cortical membranes. Structure-activity relationship studies indicate that a cyano group is a good replacement for the nitro group in the 5-position of licostinel while 5-carboxy, 5-ester, 5-ketone and 5-amide derivatives showed reduced potency. 5,6-Cyclized analogues of licostinel also showed significantly reduced potency. Among the trisubstituted QXs investigated, 5-cyano-6,7-dichloro QX and 5-cyano-7-chloro-6-methyl QX are the most potent with IC50 values of 32 nM and 26 nM, respectively.

  Despite very low in vitro cytotoxicities, several of the compounds had moderate levels of in vivo antileukemic effects. However, the most interesting aspect of their biological activity was the lack of cross-resistance shown to an amsacrine-resistant P388 cell line, suggesting that these compounds may not express their cytotoxicity via interaction with topoisomerase II.
