Glycosylation is a promising approach to overcome antimicrobial drug resistance. In this study, we investigated Koenigs-Knorr and phase transfer glycosylation on novobiocin. While the former only gave a 4'-OH product, the later produced mainly a kinetic controlled 5-OH product, but still achieved the 4'-OH modification and novoise-glycosylated products (with stronger base), as well as a diglycosylated
糖基化是克服抗菌药物耐药性的一种有前途的方法。在这项研究中,我们调查了新霉素的Koenigs-Knorr和相转移糖基化作用。尽管前者仅产生4'-OH产物,但后者主要产生动力学控制的5-OH产物,但仍实现了4'-OH修饰和新糖基化的产物(具有更强的碱)以及二糖基化的化合物。对抗菌活性的研究表明,半乳糖部分的存在可能通过增加细胞摄取来帮助提高活性。
