Quinolones are one of the most extensively used therapeutic families of antibiotics. However, the increase in antibiotic-resistant bacteria has rendered many of the available compounds useless. After applying our prediction model of activity against to a library of 1000 quinolones, two quinolones were selected to be synthesized. Additionally, a series of zwitterionic quinolonates were also synthesized. Quinolones and zwitterionic quinolonates were obtained by coupling the corresponding amine with reagent in acetonitrile. Antibacterial activity was assessed using a microdilution method. All the compounds presented antibacterial activity, especially quinolones and , selected by the prediction model, which had broad-spectrum activity. Furthermore, a new type of zwitterionic quinolonate with antibacterial activity was found. These compounds can lead to a new line of antimicrobials, as the structures, and, therefore, their properties, are easily adjustable in the amine in position 4 of the pyridine ring.
喹诺酮类是使用最为广泛的抗生素治疗药物类别之一。然而，抗生素耐药菌的增加已使许多现有化合物变得无用。在将我们针对喹诺酮类的活性预测模型应用于1000种喹诺酮类化合物库后，选择了两种喹诺酮类化合物进行合成。此外，还合成了一系列两性离子喹诺酮酸盐。喹诺酮类和两性离子喹诺酮酸盐是通过在乙腈中将相应的胺与试剂 偶联而得到的。使用微量稀释法评估抗菌活性。所有化合物均表现出抗菌活性，尤其是预测模型选择的喹诺酮类化合物 和 ，它们具有广谱活性。此外，还发现了一种新型的具有抗菌活性的两性离子喹诺酮酸盐。这些化合物可引领新型抗菌药物的研发，因为其结构以及相应的性质在吡啶环4位的胺基部分易于调节。
