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 26 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.

Phytomedical compounds as promising therapeutic agents for COVID-19 targeting angiotensin-converting enzyme 2: a review,
Journal of Pharmacy and Pharmacology,
doi:10.1093/jpp/rgae101
Abstract Aims The aim of the present review was to highlight natural product investigations in silico and in vitro to find plants and chemicals that inhibit or stimulate angiotensin-converting enzyme 2 (ACE-2). Background The global reduction of incidents and fatalities attributable to infections with SARS-CoV-2 is one of the most public health problems. In the absence of specific therapy for coronavirus disease 2019 (COVID-19), phytocompounds generated from plant extracts may be a promising strategy worth further investigation, motivating researchers to evaluate the safety and anti-SARS-CoV-2 effectiveness of these ingredients. Objective To review phytochemicals in silico for anti-SARS-CoV-2 activity and to assess their safety and effectiveness in vitro and in vivo. Methods The present review was conducted using various scientific databases and studies on anti-SARS-CoV-2 phytochemicals were analyzed and summarized. The results obtained from the in silico screening were subjected to extraction, isolation, and purification. The in vitro studies on anti-SarcoV-2 were also included in this review. In addition, the results of this research were interpreted, analyzed, and documented on the basis of the bibliographic information obtained. Results This review discusses recent research on using natural remedies to cure or prevent COVID-19 infection. The literature analysis shows that the various herbal preparations (extracts) and purified compounds can block the replication or entrance of the virus directly to carry out their anti-SARS-CoV-2 effects. It is interesting to note that certain items can prevent SARS-CoV-2 from infecting human cells by blocking the ACE-2 receptor or the serine protease TMPRRS2. Moreover, natural substances have been demonstrated to block proteins involved in the SARS-CoV-2 life cycle, such as papain- or chymotrypsin-like proteases. Conclusion The natural products may have the potential for use singly or in combination as alternative drugs to treat/prevent COVID-19 infection, including blocking or stimulating ACE-2. In addition, their structures may provide indications for the development of anti-SARS-CoV-2 drugs.

Targeting SARS-CoV-2 Spike and Main protease with phytochemicals from Herbs and spices: Molecular Docking and dynamics simulation studies.,

Abstract COVID-19, a pandemic disease has affected 480 million people and caused 6 million deaths around the world. Despite the progress made in COVID-19 drug discovery, SARS-CoV-2, the causative agent of this disease continuously mutates and rapidly evolves into new variants. This increases the challenges in drug discovery for COVID-19. As natural products serve as sources of drugs forever, this study applies computational techniques in predicting the natural compounds in herbs and spices of household origin as SARS-CoV-2 spike and protease inhibitors and also verifies the top hits against spike and protease mutants associated with SARS-CoV-2 variants of concern. This study reveals Hesperidin, Diosgenin, Fenugreekine, Epigallocatechin gallate and Quercetin as SARS-CoV-2 spike and protease inhibitors, which acts better than the drug Remdesivir. The efficiency of the top hits was also been verified against the mutants, which reveals Diosgenin and Fenugreekine as the most efficient natural compounds against SARS-CoV-2 spike mutants (N501Y, E484K, K417N and K417T), which are associated with SARS-CoV-2 variants of concern. Additionally, Hesperidin is proven to have better binding efficiency against Mpro mutants (Y54C, A191V, T190I and N142S). Overall, this study concludes that Hesperidin, Diosgenin and Fenugreekine could combat both SARS-CoV-2 and its variants effectively.
