synthesized compounds was performed against three Gram +ve and two Gram -ve bacterial strains. Results of the antimicrobial screening showed that compounds 5d, 5e, 5f, 5h and 5k have broad-spectrum antibacterial efficacy being moderately active against all the tested Gram +ve and two Gram -ve bacteria. Also, compound 5a showed interesting results being only active against Streptococcus faecalis and both
通过等摩尔比的5-亚芳基-1,3-二甲基巴比妥酸衍生物3a-d与亚甲基等摩尔比的热分解反应,以中等收率合成了一系列嘧啶并[5,4-c]喹啉-2,4-二酮衍生物5a-k。苯胺衍生物4a-d在150-180°C加热1-2小时。选择了八种合成的化合物用于使用完整的NCI 60细胞板进行的一次体外一剂抗癌试验。仅化合物5b在所用剂量(10μM)下对四种与白血病SR(GI%:51),非小细胞肺癌HOP-92(GI%:63)相对应的受试细胞系表现出中等GI% UACC-62(GI%:53)和肾癌UO-31(GI%:69)。另一方面,针对三个革兰氏+ ve和两个革兰氏-ve细菌菌株对整个合成化合物进行了抗菌筛选。抗菌筛选结果表明,化合物5d,5e,5f,5h和5k具有广谱抗菌功效,对所有测试的革兰氏+ ve细菌和两种革兰氏ve细菌均具有中等活性。同样,化合物5a显示出有趣的结果,其仅对粪链球菌具有活性,
