series of 7-[3-(1-aminoalkyl and 1-aminocycloalkyl)-1-pyrrolidinyl] quinolones have been prepared and their biological properties evaluated. Among them, 1-(S)-aminoalkyl derivatives exhibited potent antibacterial activities against gram-positive and gram-negative organisms. They had moderate lipophilicity and high aqueous solubility compared to their aminomethyl counterparts; e.g., the 3-(1-aminoethyl)-1-pyrrolidinyl
已经制备了一系列的7- [3-(1-氨基烷基和1-氨基环烷基)-1-吡咯烷基]喹诺酮并评估了它们的生物学特性。其中,1-(S)-氨基烷基衍生物对革兰氏阳性和革兰氏阴性生物显示出有效的抗菌活性。与氨基甲基同类物相比,它们具有中等的亲脂性和较高的水溶性。例如,3-(1-氨基乙基)-1-吡咯烷基化合物(83)的药代动力学特性优于其氨基甲基对应物(6)。
