butane-1-sulfonate (6a,b), were screened for their antimicrobial and antifungal activities. Among all tested compounds, it was found that compound 4-(4-carboxypyridinium-1-yl)butane-1-sulfonate (2f) showed high activity against Gram-positive bacteria, Gram-negative bacteria, and tested fungi. Most of the compounds showed a moderate degree of antimicrobial activity. The structures of these compounds were
图形摘要摘要 1,3-丙烷和/或1,4-丁烷磺内酯(磺内酯是羟基磺酸的内酯)用作化学中间体,将磺丙基和/或磺丁基引入杂环分子并赋予水溶性和分子的阴离子特性。因此,描述了三种新型官能化 N-磺酸盐的合成。这些磺酸盐含有具有潜在生物活性的吡啶基 (2a-f)、喹啉基 (4a-m) 和异喹啉基 (6a,b) 官能团。合成的季铵盐、3-(2 或 4-芳基吡啶鎓-1-基)丙烷或丁烷-1-磺酸盐 (2a–f)、3-(烷基喹啉鎓-1-基)丙烷或丁烷-1-磺酸盐 (4a) -m) 和 3-(烷基异喹啉鎓-1-基)丙烷或丁烷-1-磺酸盐 (6a,b) 的抗微生物和抗真菌活性。在所有测试的化合物中,发现化合物 4-(4-carboxypyridinium-1-yl)butane-1-sulfonate (2f) 对革兰氏阳性菌、革兰氏阴性菌和测试真菌显示出高活性。大多数化合物显示出中等程度的抗微生物活性。这些
