sensors, chelating fragmentlibraries of quinoline- and benzimidazole-sulfonamides have been prepared and screened against several different zinc(II)-dependent matrix metalloproteinases (MMPs). The fragments show impressive inhibition of these metalloenzymes and preferences for different MMPs based on the nature of the chelating group. The findings show that focused chelatorlibraries are a powerful strategy
源自小分子锌 (II) 离子传感器领域的广泛工作,已经制备了喹啉和苯并咪唑磺酰胺的螯合片段库,并针对几种不同的锌 (II) 依赖性基质金属蛋白酶 (MMP) 进行了筛选。基于螯合基团的性质,这些片段显示出对这些金属酶的显着抑制和对不同 MMP 的偏好。研究结果表明,聚焦螯合剂文库是发现用于金属蛋白抑制的先导片段的有力策略。

in situ-produced CO gas for C–Hbondcarbonylation using earth-abundant cobalt catalysts. The ease of handling CO2 gas at atmospheric pressure allows us to prepare 13C labelled compounds which are otherwise difficult to achieve. The procedure developed makes it possible to utilize CO2 as a CO source, which can be widely applied as a C1 synthon that can be incorporated between C–H and N–H bonds of aromatic

Cobalt catalyzed electrochemical [4 + 2] annulation of sulfonamides with alkynes is demonstrated in this work, which provided a practical and environmentally friendly way to synthesize structurally diverse sultams.
We report a method for cobalt-catalyzed, aminoquinoline-directed sp2 C–H bond carbonylation of sulfonamides. The reactions proceed in a dichloroethane solvent, and employ diisopropyl azodicarboxylate as a carbonmonoxide source, Mn(OAc)2 as a cooxidant and potassium pivalate as a base. Halogen, ester, and amide functionalities are compatible with the reaction conditions. This method allows for a short
