The metalloproteinase meprin β emerged as a current drug target for the treatment of a number of disorders, among those fibrosis, inflammatory bowel disease and Morbus Alzheimer. A major obstacle in the development of metalloprotease inhibitors is target selectivity to avoid side effects by blocking related enzymes with physiological functions. Here, we describe the structure-guided design of a novel series of compounds, based on previously reported highly active meprin β inhibitors. The bioisosteric replacement of the sulfonamide scaffold gave rise to a next generation of meprin inhibitors. Selected compounds based on this novel amine scaffold exhibit high activity against meprin β and also remarkable selectivity over related metalloproteases, i.e., matrix metalloproteases and A disintegrin and metalloproteinases.

下一代Meprinβ抑制剂的结构指导设计，合成和表征

金属蛋白酶甲铁蛋白β已成为治疗许多疾病的当前药物靶标，这些疾病包括纤维化，炎性肠病和Morbus Alzheimer。开发金属蛋白酶抑制剂的主要障碍是靶标选择性，以通过阻断具有生理功能的相关酶来避免副作用。在这里，我们基于先前报道的高活性甲羟乙炔β抑制剂描述了一系列新型化合物的结构指导设计。磺酰胺支架的生物立体替代产生了新一代的meprin抑制剂。基于这种新型胺支架的选定化合物显示出对甲羟乙炔β的高活性，并且对相关的金属蛋白酶（即基质金属蛋白酶和A整联蛋白和金属蛋白酶）具有显着的选择性。
