In Vitro study of compounds from Huashi Baidu (Q-14), showing dose-dependent inhibition of SARS-CoV-2 with quercetin. Authors also perform a mouse study showing that Q-14 decreases SARS-CoV-2 viral load and reduces pulmonary inflammation.Among 60 compounds, six (magnolol, glycyrrhisoflavone, licoisoflavone A, emodin, echinatin, and quercetin) showed dose-dependent inhibition of SARS-CoV-2, including two Mpro inhibitors (echinatin and quercetin) and two RdRp inhibitors (glycyrrhisoflavone and licoisoflavone A).

- Huashi Baidu decoction (HBF) is a traditional Chinese medicine (TCM) formula that has both antiviral and anti-inflammatory effects.
- In this study, the researchers identified six bioactive compounds from HBF that have antiviral and anti-inflammatory effects.
- The researchers also found that HBF was able to inhibit the growth of SARS-CoV-2 in cell culture and in mice.
- COVID-19 is a respiratory disease caused by the SARS-CoV-2 virus.
- There are a number of anti-COVID-19 drugs available, but they are not always effective.
- Traditional Chinese medicine (TCM) has been shown to be effective in treating COVID-19, and Huashi Baidu decoction (HBF) is a TCM formula that has been shown to have both antiviral and anti-inflammatory effects.
- In this study, the researchers identified six bioactive compounds from HBF that have antiviral and anti-inflammatory effects.
- These compounds include magnolol, glycyrrhisoflavone, licoisoflavone A, emodin, echinatin, and quercetin.
- The researchers also found that HBF was able to inhibit the growth of SARS-CoV-2 in cell culture and in mice.
- These findings suggest that HBF could be a promising new treatment for COVID-19.
The researchers concluded that HBF is a promising new treatment for COVID-19 because it has both antiviral and anti-inflammatory effects. They also suggested that further studies are needed to confirm the efficacy and safety of HBF in clinical trials.
Bioactive compounds from Huashi Baidu decoction possess both antiviral and anti-inflammatory effects against COVID-19
Proceedings of the National Academy of Sciences, doi:10.1073/pnas.2301775120
Significance Huashi Baidu decoction (Q-14), a famous traditional Chinese medicine decoction for COVID-19, has good effects on SARS-CoV-2 RNA clearance, promoting lung lesion opacity absorption, reducing inflammation, and ameliorating flu-like symptoms based on a series of clinical trials, having potent antiviral and antiinflammatory effects. However, due to the lack of systematic and in-depth research, little significant progress has been made in the study of TCMT-NDRD of HBF for COVID-19 management. Therefore, the aim of the current study was to identify key antiviral and anti-inflammatory bioactive compounds from HBF based on an integrative pharmacological strategy. These findings will greatly stimulate the traditional Chinese medicine theory-driven natural drug discovery against COVID-19 and promote the modern research of Chinese medicine.
