ramoplanin A2 aglycon, a potent antibiotic that inhibits bacterial cell wall biosynthesis, is detailed. As a consequence of both its increased stability (lactam vs lactone) and its "relative" ease of synthesis, the alanine scan was conducted on [Dap2]ramoplanin A2 aglycon, which possesses antimicrobial activity equal to or slightly more potent than that of ramoplanin A2 or its aglycon. Thus, 14 key
在定义每个残基的重要性并确定分子的关键区域的工作中,详细介绍了 ramoplanin A2 苷元的丙氨酸扫描,这是一种抑制细菌细胞壁生物合成的强效抗生素。由于其稳定性(内酰胺与内酯)的增加及其“相对”易于合成,对 [Dap2] 雷莫拉宁 A2 苷元进行了丙氨酸扫描,其具有与雷莫拉宁 A2 相同或略强的抗菌活性或其苷元。因此,制备了 ramoplanin A2 苷元的 14 个关键类似物,代表残基 3-13、15 和 17 的扫描,采用收敛的溶液相全合成,将努力巩固到可管理的水平。
