The main viral protease (Mpro) of SARS-CoV-2 is a nucleophilic cysteine hydrolase and a current target for anti-viral chemotherapy. We describe a high-throughput solid phase extraction coupled to mass spectrometry Mpro assay. The results reveal some β-lactams, including penicillin esters, are active site reacting Mpro inhibitors, thus highlighting the potential of acylating agents for Mpro inhibition.

质谱揭示β-内酰胺作为SARS-CoV-2 Mpro抑制剂的潜力

SARS-CoV-2的主要病毒蛋白酶 (M pro ) 是亲核半胱氨酸水解酶,目前是抗病毒化疗的靶标。我们描述了一种高通量固相萃取与质谱 M pro检测相结合的方法。结果表明,一些 β-内酰胺,包括青霉素酯,是 M pro抑制剂的活性位点反应,因此突出了酰化剂对 M pro抑制的潜力。
