Summary
Baicalein and baicalin show antiviral activity against SARS-CoV-2, the virus causing COVID-19. Baicalein specifically inhibits the viral RNA-dependent RNA polymerase, offering a potential new therapeutic strategy for COVID-19 treatment.
Area of Science:
- Virology
- Pharmacology
Background:
- Coronavirus Disease 2019 (COVID-19), caused by SARS-CoV-2, is a global pandemic.
- Limited antiviral treatments exist, highlighting the urgent need for new therapies.
Purpose of the Study:
- To investigate the antiviral activity of baicalein and baicalin against SARS-CoV-2.
- To identify the mechanism of action for these compounds as potential COVID-19 therapeutics.
Main Methods:
- In vitro studies using cell-based and biochemical assays.
- Analysis of SARS-CoV-2 RNA-dependent RNA polymerase (RdRp) inhibition.
- Assessment of baicalein binding to SARS-CoV-2 RdRp.
Main Results:
- Baicalein and baicalin demonstrated significant in vitro antiviral activity against SARS-CoV-2.
- Both compounds were identified as direct inhibitors of SARS-CoV-2 RdRp.
- Baicalein exhibited greater potency and specific binding to the viral RdRp.
Conclusions:
- Baicalein and baicalin possess potent antiviral properties against SARS-CoV-2.
- Baicalein's specific inhibition of SARS-CoV-2 RdRp positions it as a promising candidate for COVID-19 drug development.

Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

01:23RNA Interference
27.0K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

6.7K
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

02:28Leaky Scanning
5.4K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

17.5K
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...

10.3K
Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a...
