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。

The present disclosure provides compounds having the general structure A or pharmaceutically acceptable salts thereof:
R—X (A)
wherein R is an alkyl or aryl moiety comprising heterocyclic structures; and X is a metal-chelatin group selected from:
This disclosure further provides a focused library of compounds for use in the discovery and design of metallo-enzyme inhibitors. This fragment-based approach provides an assembly of a library of low molecular weight compounds (MW<300 Da) containing a variety of potential metal-chelating groups. The identification of the inhibitory scaffolds among these compounds provides the initial hit fragments that may be optimized for affinity against a particular target using common medicinal chemistry, structure-based or NMR-based approaches.
