The treatment is a protease inhibitor, a class of drug used to treat HIV and hepatitis C. The drug could potentially be used against other coronaviruses, in addition to COVID-19. Filling the gap in the literature, this book presents everything there is to know about this topic. Again, because it does not show the potential for “overlapping or additive toxicity” with the drugs in current use for COVID-19 treatment, which means it can be combined with these agents with ease in humans. It is a cysteine protease and a member of the PA clan of proteases.It has a cysteine-histidine catalytic dyad at its active site and cleaves a Gln-(Ser/Ala/Gly) peptide bond. This enzyme being conserved across several CoVs. Protease inhibitors have played a similar role in HIV and HCV therapeutics. This cleaving process is performed by two viral proteases: main protease (M pro, also named 3CL protease) and papain-like protease . The Phase 1 trial is a randomized, double-blind, sponsor-open, placebo-controlled, single- and multiple-dose escalation study in healthy adults evaluating the safety, tolerability and pharmacokinetics of PF-07321332. Scientists using the Advanced Photon Source have discovered that a drug used to fight tumors in animals might be effective against many types of coronaviruses, including SARS-CoV-2. The researchers examined the ability of PF-00835231 to exert antiviral activity against SARS-CoV-2 in cell culture, using a cytopathic effect (CPE) assay. Evaluation of the combined activity of these drugs led to the finding that while the in vitro EC50 for PF-00835231 alone was 0.14 μM, and for remdesivir, it was 0.074μM, in combination, they showed a mix of synergistic and additive effects.
