The synthesis of ten novel 3-cyano-8-methyl-2-oxo-1,4-disubstituted-1,2,5,6,7,8-hexahydro-quinolines supported with benzensulfonyl and phenylthiocarbamoyl pharmacophores that are known to contribute to potential chemotherapeutic effects is described. They were evaluated in vitro for their antimicrobial activity against eight different microorganisms and for their cytotoxic effects against three different human tumor cell lines. The results revealed that nine compounds displayed variable inhibitory effects on the growth of the tested Gram-positive and Gram-negative bacteria with special pronounced activity against S. aureus and E. coli bacterial strains, in addition to a moderate antifungal activity against C. albicans. On the other hand, six compounds were able show remarkable cytotoxic efficiency against human colon carcinoma HT29, hepatocellular carcinoma Hep-G2 and Caucasian breast adenocarcinoma MCF7 cell lines. Collectively, the results would suggest that compounds 15 and 16 could be considered as possible dual antimicrobial-anticancer agents.
描述了十种新型3-氰基-8-甲基-2-氧代-1,4-双取代-1,2,5,6,7,8-六氢喹啉的合成,这些化合物带有已知对潜在化疗效果有贡献的苯磺酰基和苯硫氨基药效团。它们在体外评估了对八种不同微生物的抗微生物活性和对三种不同人类肿瘤细胞系的细胞毒性效果。结果显示,九种化合物对被测试的革兰氏阳性和革兰氏阴性细菌的生长表现出不同的抑制效果,特别是在对金黄色葡萄球菌(S. aureus)和大肠杆菌(E. coli)菌株上具有显著的活性,同时对念珠菌(C. albicans)表现出中等的抗真菌活性。另一方面,六种化合物在对人类结肠癌HT29、肝细胞癌Hep-G2和高加索乳腺腺癌MCF7细胞系上显示出显著的细胞毒性效果。总体而言,结果表明化合物15和16可以被视为可能的双重抗微生物-抗癌剂。
