COVID-19 Treatment Clinical Evidence
COVID-19 involves the interplay of 500+ viral and host proteins and factors, providing many therapeutic targets.
c19early analyzes 6,000+ studies for 220+ treatments—over 17 million hours of research.
Only three high-profit early treatments are approved in the US.
In reality, many treatments reduce risk,
with 25 low-cost treatments approved across 163 countries.
-
Naso/
oropharyngeal treatment Effective Treatment directly to the primary source of initial infection. -
Healthy lifestyles Protective Exercise, sunlight, a healthy diet, and good sleep all reduce risk.
-
Immune support Effective Vitamins A, C, D, and zinc show reduced risk, as with other viruses.
-
Thermotherapy Effective Methods for increasing internal body temperature, enhancing immune system function.
-
Systemic agents Effective Many systemic agents reduce risk, and may be required when infection progresses.
-
High-profit systemic agents Conditional Effective, but with greater access and cost barriers.
-
Monoclonal antibodies Limited Utility Effective but rarely used—high cost, variant dependence, IV/SC admin.
-
Acetaminophen Harmful Increased risk of severe outcomes and mortality.
-
Remdesivir Harmful Increased mortality with longer followup. Increased kidney and liver injury, cardiac disorders.

, Investigating the Binding Mode of a Naphthol‐Based Inhibitor Targeting SARS‐CoV‐2 Main Protease, ChemMedChem, doi:10.1002/cmdc.70448
Regardless of the massive global efforts to combat the virus causing SARS‐CoV‐2 syndrome, the infection remains a substantial health challenge worldwide in the years following 2019. To this direction, targeting the main viral protease M pro has been proposed as a tractable and particularly promising approach toward developing effective and safe COVID‐19 antivirals. By applying an integrated workflow combining a previously developed in silico consensus ranking protocol with two orthogonal in vitro methods, the NCI/DTP repository is screened and the discovery of an original naphthol scaffold with M pro inhibitory properties is reported. The hit is characterized in terms of structure and binding thermodynamics by combining X‐ray crystallography and isothermal titration calorimetry where a binding affinity constant of 1.55 μM is determined. The compound is further evaluated against virus‐infected cells, where an EC 50 value of 7.23 μM and comparable toxicity with nirmatrelvir are measured. Chemical synthesis is additionally employed to facilitate optimal exploration of the structure–activity relationship landscape regarding the new hit. By integrating computational, biophysical, and enzymatic methods, the suggested approach allows the combination of a structural hypothesis with functional evidence and shows its capacity toward identifying and rationally optimizing structurally original noncovalent M pro inhibitors.
