The coronavirus disease 2019 (COVID-19) pandemic has necessitated the development of antiviral agents against severe acute respiratory syndrome 2 (SARS-CoV-2). 3C-like protease (3CLpro) is a promising target for COVID-19 treatment. Here, we report new class covalent inhibitors 3CLpro that possess chlorofluoroacetamide (CFA) as cysteine-reactive warhead. Based on an aza-peptide scaffold, synthesized series CFA derivatives in enantiopure form and evaluated their biochemical efficiency. data revealed 8a (YH-6) with R configuration at unit strongly blocks SARS-CoV-2 replication infected cells, its potency comparable to nirmatrelvir. X-ray structural analysis showed YH-6 formed bond Cys145 catalytic center 3CLpro. strong activity favorable pharmacokinetic properties suggest potential lead compound treatment COVID-19.

SARS-CoV-2 is the causative agent of COVID-19 pandemic. The approval vaccines and small-molecule antivirals vital in combating viral polymerase inhibitors remdesivir molnupiravir main protease inhibitor nirmatrelvir/ritonavir have been approved by U.S. FDA. However, emergence variants concern/interest calls for additional with novel mechanisms action. papain-like (PLpro) mediates cleavage polyprotein modulates host's innate immune response upon infection, rendering it a promising antiviral drug target. This Perspective highlights major achievements structure-based design high-throughput screening PLpro since beginning Encouraging progress includes non-covalent favorable pharmacokinetic properties first-in-class covalent inhibitors. In addition, we offer our opinion on knowledge gaps that need to be filled advance clinic.

The viral main protease is one of the most attractive targets among all key enzymes involved in SARS-CoV-2 life cycle. Covalent inhibition cysteine145 MPRO with selective antiviral drugs will arrest replication process virus without affecting human catalytic pathways. In this Perspective, we analyzed silico, vitro, and vivo data representative examples covalent inhibitors reported literature to date. particular, studied molecules were classified into eight different categories according their reactive electrophilic warheads, highlighting differences between reversible/irreversible mechanism inhibition. Furthermore, analyses recurrent pharmacophoric moieties stereochemistry chiral carbons reported. noncovalent silico protocols, provided would be useful for scientific community discover new more efficient inhibitors.

The U.S. FDA approval of PAXLOVID, a combination therapy nirmatrelvir and ritonavir has significantly boosted our morale in fighting the COVID-19 pandemic. Nirmatrelvir is an inhibitor main protease (MPro) SARS-CoV-2. Since many SARS-CoV-2 variants that resist vaccines antibodies have emerged, concern acquired viral resistance to naturally arises. Here, possible mutations MPro confer evasion are analyzed discussed from both evolutionary structural standpoints. analysis indicates those will likely reside whole aa45–51 helical region residues including M165, L167, P168, R188, Q189. Relevant also been observed existing samples. Implications this fight against future drug-resistant development broad-spectrum antivirals as well.

Abstract The outbreak of COVID-19 has become a global crisis, and brought severe disruptions to societies economies. Until now, effective therapeutics against are in high demand. Along with our improved understanding the structure, function, pathogenic process SARS-CoV-2, many small molecules potential anti-COVID-19 effects have been developed. So far, several antiviral strategies were explored. Besides directly inhibition viral proteins such as RdRp M pro , interference host enzymes including ACE2 proteases, blocking relevant immunoregulatory pathways represented by JAK/STAT, BTK, NF-κB, NLRP3 pathways, regarded feasible drug development. development treat achieved strategies, computer-aided lead compound design screening, natural product discovery, repurposing, combination therapy. Several representative remdesivir paxlovid proved or authorized emergency use countries. And candidates entered clinical-trial stage. Nevertheless, due epidemiological features variability issues it is necessary continue exploring novel COVID-19. This review discusses current findings for treatment. Moreover, their detailed mechanism action, chemical structures, preclinical clinical efficacies discussed.

Covalent inhibitors and other types of covalent modalities have seen a revival in the past two decades, with variety new targeted drugs having been approved recent years. A key feature such molecules is an intrinsically reactive group, typically weak electrophile, which enables irreversible or reversible formation bond specific amino acid target protein. This often called "warhead", critical determinant ligand's activity, selectivity, general biological properties. In 2019, we summarized emerging re-emerging warhead chemistries to cysteine acids (Gehringer, M.; Laufer, S. A. J. Med. Chem. 62, 5673−5724; DOI: 10.1021/acs.jmedchem.8b01153). Since then, field has rapidly evolved. Here discuss progress on warheads made since our last Perspective their application medicinal chemistry chemical biology.

Nirmatrelvir (PF-07321332) is a nitrile-bearing small-molecule inhibitor that, in combination with ritonavir, used to treat infections by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). interrupts the viral life cycle inhibiting SARS-CoV-2 main protease (Mpro), which essential for processing polyproteins into functional nonstructural proteins. We report studies reveal that derivatives of nirmatrelvir and other Mpro inhibitors nonactivated terminal alkyne group positioned similarly electrophilic nitrile can efficiently inhibit isolated replication cells. Mass spectrometric crystallographic evidence shows apparent irreversible covalent reactions active site cysteine (Cys145), while analogous nitriles react reversibly. The results highlight potential inhibition nucleophilic proteases alkynes, which, contrast nitriles, be functionalized at their position optimize selectivity, as well pharmacodynamic pharmacokinetic properties.
