Insights

Researchers are investigating repurposed antiviral drugs and new vaccines to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus causing COVID-19. This review details drug mechanisms, toxicities, and clinical trials for potential COVID-19 treatments.

Area of Science:

  • Virology
  • Infectious Diseases
  • Pharmacology

Background:

  • The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in December 2019 has led to the global COVID-19 pandemic.
  • The World Health Organization declared a pandemic, and numerous states declared emergencies due to the widespread impact of COVID-19.
  • The lack of specific treatments for COVID-19 has prompted urgent research into therapeutic strategies.

Purpose of the Study:

  • To provide a comprehensive review of repurposed antiviral drugs for treating COVID-19.
  • To elucidate the mechanisms of action, associated toxicities, and clinical trial outcomes of these repurposed agents.
  • To highlight ongoing efforts in developing new vaccine candidates against SARS-CoV-2.

Main Methods:

  • Computational approaches were employed to screen extensive antiviral compound libraries for potential efficacy against SARS-CoV-2.
  • Existing antiviral agents developed for other viral infections were identified for repurposing.
  • A review of preclinical and clinical data for select repurposed drugs and vaccine candidates was conducted.

Main Results:

  • Advances in computational drug screening have accelerated the identification of potential SARS-CoV-2 therapeutics.
  • Several repurposed drugs are under investigation, with ongoing clinical trials evaluating their effectiveness and safety.
  • New vaccine candidates are progressing through preclinical and clinical development stages.

Conclusions:

  • Repurposing existing antiviral drugs represents a viable strategy in the race to find effective COVID-19 treatments.
  • Understanding the mechanism of action and toxicity profiles of repurposed agents is crucial for their clinical application.
  • Continued research and development of both repurposed drugs and novel vaccines are essential to combat the COVID-19 pandemic.

Subviral Agents01:29

Subviral Agents

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

siRNA - Small Interfering RNAs02:30

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

Enzyme Inhibition01:30

Enzyme Inhibition

Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.

Pharmacokinetics: Drug–Food and Drug–Viral Interactions01:26

Pharmacokinetics: Drug–Food and Drug–Viral Interactions

A drug interaction occurs when the concurrent use of another drug, food, or an external substance alters the pharmacological activity of a drug. This interaction can modify the action of the original drug, affecting its effectiveness and safety.Drug–food interactions are significant as they impact drug absorption, metabolism, and excretion. For example, grapefruit juice is a well-known disruptor of drug metabolism. It inhibits the cytochrome P450 3A4 enzyme, crucial for the metabolism of...

Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors01:30

Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors

Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...
