important for good Gram positive activity. For 1-cyclopropyl 7-(2,6-dimethyl-4-pyridinyl) derivatives, the 6-fluoro 4a, 8-fluoro 10d, 6,8-difluoro 10b, and 5,6,8-trifluoro 8, all provided equal antibacterial activity against Staphylococcus aureus ATCC 29213. There is also a correlation between the substitution on the 7-(4-pyridinyl) group and the Gram positive activity, particularly for S. aureus, clearly
3-和4-(三烷基锡烷基)吡啶与7-溴或7-氯1取代的1,4-二氢-4-氧代-3-喹啉羧酸酯的钯催化偶联提供了相应的1取代的1, 4-二氢-4-氧代-7-吡啶基-3-喹啉羧酸。研究了这些衍生物的抗菌活性,发现革兰氏阳性活性的最佳1位和7位取代基分别是环丙基和4-(2,6-二甲基吡啶基)。我们发现对于所研究的氟取代的衍生物,氟在喹诺酮核上的位置或氟原子的数目对于良好的革兰氏阳性活性似乎并不重要。对于1-环丙基7-(2,6-二甲基-4-吡啶基)衍生物,6-氟4a,8-氟10d,6,8-二氟10b和5,6,8-三氟8 所有这些都对金黄色葡萄球菌ATCC 29213具有相同的抗菌活性。7-(4-吡啶基)基团的取代与革兰氏阳性活性之间也存在相关性,特别是对金黄色葡萄球菌,这清楚地表明2,6-二甲基吡啶基组是最佳的。在这项研究中,针对金黄色葡萄球菌ATCC 29213的最有效药物的MIC50值为0.0
