Activity-based probes (ABPs) are covalent chemical tools that are widely used to target proteases in chemical biology. Here, we report a series of novel ABPs for the serine protease furin with phosphonate and phosphinate esters as reactive electrophiles. We show that these probes covalently label furin and have nanomolar potencies, because of proposed interactions with the different recognition pockets around the active site of furin.
基于活性的探针(ABPs)是共价化学工具,在化学生物学中广泛用于靶向蛋白酶。在此,我们报道了一系列以膦酸酯和次膦酸酯作为反应性亲电试剂的新型针对丝氨酸蛋白酶弗林蛋白酶的ABPs。我们表明,由于与弗林蛋白酶活性位点周围不同识别口袋的假定相互作用,这些探针可共价标记弗林蛋白酶且具有纳摩尔级别的效力。
