In this work, we described the formation of polymeric networks with potential antimicrobial character based on an acrylate oligomer, poly(mannitol sebacate) (PMS), and an enzymatically synthesized methacrylic monomer with thiazole groups (MTA). Networks with different content of MTA were prepared, and further physico-chemically characterized by microhardness, water contact angle measurements, and differential scanning calorimetry. Monomer incorporation into the networks and subsequent quaternization to provide thiazolium moieties affected the mechanical behavior and the surface wettability of the networks. Moreover, the introduction of permanent cationic charges in the network surface could give antimicrobial activity to them. Therefore, the antibacterial behavior and the hemotoxicity were analyzed against Gram-positive and Gram-negative bacteria and red blood cells, respectively.
在本研究中,我们描述了基于丙烯酸酯低聚物、聚(癸二酸甘露醇酯)(PMS)和酶促合成的含噻唑基团的甲基丙烯酸单体(MTA)形成具有潜在抗菌特性的聚合物网络。制备了具有不同MTA含量的网络,并通过显微硬度、水接触角测量和差示扫描量热法对其进行了进一步的物理化学表征。单体掺入网络并随后进行季铵化以提供噻唑鎓部分影响了网络的机械性能和表面润湿性。此外,在网络表面引入永久性阳离子电荷可赋予其抗菌活性。因此,分别针对革兰氏阳性菌和革兰氏阴性菌以及红细胞分析了抗菌行为和血液毒性。
