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。
Aminoquinoline-directed, cobalt-catalyzed carbonylation of sulfonamide sp<sup>2</sup> C–H bonds
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

The use of cobalt as catalyst in direct CH activation protocols as a replacement for more expensive second row transition metals is currently attracting significant attention. Herein we disclose a facile cobalt-catalyzed CH functionalization route towards sultammotifsthroughannulation of easily prepared arylsulfonamides and alkynesusing8-aminoquinoline as a directinggroup. The reaction shows
The present invention relates to novel hepcidin antagonists, pharmaceutical compositions comprising them and the use thereof as medicaments for the use in the treatment of iron metabolism disorders, such as, in particular, iron deficiency diseases and anemias, in particular anemias in connection with chronic inflammatory diseases.

The Rh(I)-catalyzed ortho-alkylation of benzenesulfonamides with alkenes with the aid of an 8-aminoquinoline directing group is reported. The reaction is applicable to a variety of benzenesulfonamide derivatives and various alkenes. Curiously, unactivated 1-alkenes were more reactive than activated alkenes. Deuterium labeling experiments indicate that an unusual 1,2-H shift mechanism to generate a
