To provide a novel mutilin derivative having a substitution at the 14-position, which is a novel mutilin analogue exhibiting a potent and broad antimicrobial action against Gram-positive bacteria and Gram-negative bacteria including various drug-resistant bacteria, and which is expected to be useful as an agent for treating infectious diseases. A mutilin derivative represented by the following general formula (1):
or a pharmaceutically acceptable addition salt thereof.

Limited chemical shift dispersion represents a significant barrier to studying multistate equilibria of large membrane proteins by 19F NMR. We describe a novel monofluoroethyl 19F probe that dramatically increases the chemical shift dispersion. The improved conformational sensitivity and line shape enable the detection of previously unresolved states in one-dimensional (1D) 19F NMR spectra of a 134
有限的化学位移色散是通过19 F NMR 研究大膜蛋白多态平衡的重大障碍。我们描述了一种新型单氟乙基19 F 探针,可显着增加化学位移色散。改进的构象灵敏度和线形使得能够检测 134 kDa 膜转运蛋白的一维 (1D) 19 F NMR 谱中先前未解析的状态。这些状态的群体响应配体结合、突变和温度的变化与单粒子冷冻电子显微镜(cryo-EM)确定的结构整体中不同构象的群体变化相关。因此, 19 F NMR 可以指导样品制备,以发现和可视化新的构象状态,并促进图像分析和三维 (3D) 分类。

A mild and facile synthesis of aryl and alkenyl sulfides via copper-catalyzed deborylthiolation of organoborons with thiosulfonates
A simple, efficient, and odorless deborylthiolation of aryl- and alkenylborons with thiosulfonates has been achieved under mild conditions using a copper catalyst.
