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.

, In Vitro Antiviral Effects of Green-Lipped Mussel Oil and Low-Molecular-Weight Fucoidan on HSV, RSV, and SARS-CoV-2 Pseudovirus, Biomedicines, doi:10.3390/biomedicines14061184
Background/Objectives: Marine-derived bioactive compounds have attracted increasing interest due to their potential antiviral properties. This study investigated in vitro antiviral activity of oil extracted from the green-lipped mussel (Perna canaliculus, GLM) and low-molecular-weight (LMW) fucoidan from Undaria pinnatifida against three human viruses in mammalian cell systems. herpes simplex virus-1 (HSV-1), respiratory syncytial virus (RSV), and SARS-CoV-2. These marine compounds were selected with the longer-term aim of evaluating their combination as a potential synergistic antiviral strategy. Methods: Antiviral efficacy was assessed using complementary assay platforms, including plaque reduction assays in mammalian cell systems and a lentiviral pseudovirus system delivering a bioluminescent reporter gene in HEK293/ACE2 cells pseudotyped with the SARS-CoV-2 spike glycoprotein. Cytotoxicity was assessed in parallel, and the selectivity index (SI) was calculated as the ratio of CC50 to IC50 for each compound and virus tested. Results: GLM oil showed potential antiviral activity against SARS-CoV-2 pseudovirus (SI > 6.20), with limited activity against RSV (SI > 3.48) and HSV-1 (SI > 2.28). In contrast, LMW fucoidan did not demonstrate antiviral activity against any of the tested viruses. Conclusions: These findings support further investigation of GLM-derived bioactive compounds as potential antiviral agents, including studies to elucidate their mechanisms of action and in vivo studies to confirm their antiviral efficacy. Combination studies were not pursued in the present work as both compounds require further optimisation individually; however, future studies should evaluate their combined antiviral potential, as synergistic or additive effects remain plausible.
, Garlic-Derived Phytochemical Candidates Predicted to Disrupt SARS-CoV-2 RBD–ACE2 Binding and Inhibit Viral Entry, Molecules, doi:10.3390/molecules30234616
The emergence of SARS-CoV-2 and its rapid global spread underscores the urgent need for novel therapeutic strategies. This study investigates the antiviral potential of Allium sativum (garlic) extracts against SARS-CoV-2, focusing on disruption of the spike protein’s receptor-binding domain (RBD) interaction with angiotensin-converting enzyme 2 (ACE2), a critical step in viral entry. Two garlic cultivars (Tigre and Fermín) were processed via oven-drying or freeze-drying, followed by maceration with CH2Cl2/MeOH (1:1) and fractionation with liquid–liquid partition. ELISA immunoassays revealed that freeze-dried Tigre (TL) extracts had the highest inhibitory activity (42.16% at 0.1 µg/mL), with its aqueous fraction achieving 57.26% inhibition at 0.01 µg/mL. Chemical profiling via GC-MS found sulfur and other types of compounds. Molecular docking identified three garlic TL-derived aqueous fraction compounds with strong binding affinities (ΔG = −7.5 to −6.9 kcal/mol) to the RBD-ACE2 interface. Furthermore, ADME in silico analysis highlighted one of them (L17) as the main candidate, having high gastrointestinal absorption, blood–brain barrier permeability, and compliance with drug-likeness criteria. These findings underscore garlic-derived compounds as promising inhibitors of SARS-CoV-2 entry, calling for further preclinical validation. The study integrates experimental and computational approaches to advance natural product-based antiviral discovery, emphasizing the need for standardized formulations to address therapeutic variability across viral variants.
