== Function ==
[https://www.uniprot.org/uniprot/K4L8Z7_9CALI K4L8Z7_9CALI] 3C-like protease processes the polyprotein: 3CLpro-RdRp is first released by autocleavage, then all other proteins are cleaved. May cleave polyadenylate-binding protein thereby inhibiting cellular translation.[PROSITE-ProRule:PRU00870]

== Publication Abstract from PubMed ==
The cysteine 3C-like proteases (3CL(pro)) of caliciviruses, coronaviruses, and picornaviruses are essential for viral replication. In this study, we report the development of potent broad-spectrum peptidomimetic antiviral agents that target the 3CL(pro) of caliciviruses (NS6), coronaviruses (M(pro)), and a picornavirus (3C). Based upon previously reported inhibitors, a small library of compounds was designed, synthesized and tested to identify a core structure, which was then derivatized with a focus upon P3 and P4 positions to afford new inhibitors with improved potency against the respective viral enzymes and enhanced binding as determined by X-ray crystallography. These compounds were tested against a range of viruses in culture, revealing minimal toxicity while exhibiting broad-spectrum potent nanomolar activities against noroviruses and several coronavirus species, including alpha and omicron variants of SARS-CoV-2 and Middle East Respiratory Syndrome virus (MERS).
