SARS-CoV

SARS coronavirus

SARS-CoV is the coronavirus (CoV) that causes severe acute respiratory syndrome (SARS). CoVs are enveloped viruses with a positive-sense, single-stranded RNA and can cause health-threatening outbreaks by targeting human respiratory system, including not only SARS, but also Middle East respiratory syndrome (MERS) and SARS-CoV-2 (the cause of COVID-19).

CoVs have four main structural proteins: spike(S), membrane (M), envelope (E), and nucleocapsid (N) proteins. An S protein mediates the CoV entry into host cells by attaching to a cellular receptor (ACE2 for SARS-CoV and SARS-CoV-2, DPP4 for MERS-CoV), followed by fusion between virus and host cell membranes. Genome replication and subgenomic RNA transcription after entry carry on with the participation of many nonstructural proteins such as Mpro (main protease or 3CLpro), PLpro (papain-like protease) and RdRp (RNA-dependent RNA polymerase). Then the structural proteins are translated, assembled into mature virions, and released via vesicles by exocytosis. It is worth mentioning that a protease called TMPRSS2 (transmembrane protease, serine 2) play important roles throughout the whole life of CoVs (such as attachment, assembling and release) by cleaving S protein. All the proteins and subcellular structures participated in the life cycle of CoVs are promising targets for treatment of disease caused by CoVs.

    TFMU-ADPr triethylamine
    Inhibitor
    TFMU-ADPr triethylamine is a selective reporter substrate of SARS-CoV-2 Macro1 (IC50=0.59 μM), with an excitation wavelength (λEx) of 385 nm, and an emission wavelength (λEm) of 502 nm (or 495 nm). TFMU-ADPr triethylamine can also undergo enzymatic hydrolysis with Poly(ADP-ribose) Glycohydrolase (PARG) sourced from human, Tetrahymena thermophila and ADP-ribosylhydrolase 3 from human to release fluorophores, thereby directly reporting total poly (ADP-ribose) hydrolase activity. TFMU-ADPr triethylamine binds to the ADPr-binding site of SARS-CoV-2 Macro1, and its TFMU moiety inserts into the narrow hydrophobic groove of this protein. TFMU-ADPr triethylamine can thus be used to evaluate small-molecule inhibitors targeting PAR hydrolases under in vitro conditions, to investigate the regulatory mechanisms of ADP-ribosyl catabolic enzymes, or to detect PAR hydrolase activity in whole-cell lysate assays. TFMU-ADPr triethylamine is also applicable to COVID-19-related research.
