Discovery of orally bioavailable SARS-CoV-2 papain-like protease inhibitor as a potential treatment for COVID-19
Discovery of orally bioavailable SARS-CoV-2 papain-like protease inhibitor as a potential treatment for COVID-19

Chinese researchers:

GZNL-P36 is a promising drug candidate for COVID-19 targeting a conserved viral enzyme, showing broad antiviral and anti-inflammatory effects.

Mouse trials: it reduces viral load, inflammation, and lung damage

An orally available Mpro/TMPRSS2 bispecific inhibitor with potent anti-coronavirus efficacy in vivo
An orally available Mpro/TMPRSS2 bispecific inhibitor with potent anti-coronavirus efficacy in vivo

Researchers at The University of Hong Kong developed TMP1, an oral drug blocking coronavirus entry and replication.

Tested in mice and hamsters, it was effective against SARS-CoV-2 variants and drug-resistant strains.

Obeldesivir for COVID-19 Is Safe, Reduces Time to Symptom Relief in High-Risk Patients
Obeldesivir for COVID-19 Is Safe, Reduces Time to Symptom Relief in High-Risk Patients

My note: Would like to see study on this drug with endpoints like time to recovery, severity of symptoms, long-term follow-up for post-acute symptoms. Not holding my breath. This is, after all, Giliad, the maker of remdesivir. Still, potential early treatment option here:

465 adults received either obeldesivir or a placebo for 5 days. The results showed that those on obeldesivir had a 0% hospitalization rate and lower mortality compared to 0.5% in the placebo group.

Patients taking obeldesivir also experienced quicker symptom relief and greater reductions in the virus levels. Overall, the drug was found to be generally safe and well-tolerated.
