Shuanghuanglian for COVID-19

Shuanghuanglian may be beneficial for COVID-19 according to the studies below. COVID-19 involves the interplay of 500+ viral and host proteins and factors providing many therapeutic targets. Scientists have proposed 11,000+ potential treatments. c19early.org analyzes 220+ treatments. We have not reviewed Shuanghuanglian in detail.
Du et al., Drug Repurposing as a Broad-Spectrum Strategy Against Coronaviruses: Frontiers in Mechanisms and Clinical Translation, Viruses, doi:10.3390/v18070804
Coronaviruses (family Coronaviridae) are enveloped, positive-sense, single-stranded RNA viruses with broad host adaptability. They transmit across species among humans, livestock, companion animals, and wildlife, eliciting a disease spectrum ranging from mild respiratory and gastrointestinal symptoms to fatal multi-organ failure, thereby posing significant challenges to global health. In this context, drug repurposing has emerged as a practical strategy for rapidly identifying broad-spectrum antivirals against emerging and re-emerging coronaviruses. Using coronaviruses as a paradigm, this review systematically summarizes research advances and mechanistic insights into the repurposing of existing drugs against coronaviruses. Simultaneously, we dissect core challenges including species-specific pharmacokinetic disparities, insufficient inter-genera conservation of viral targets, and systemic barriers between human and veterinary drug regulatory frameworks and propose innovative solutions encompassing AI-driven cross-species drug prediction, next-generation cross-species infection models, and a “human-veterinary dual-track” collaborative research and development system. Collectively, this review highlights the promise of drug repurposing as a broad-spectrum antiviral strategy and provides a translational perspective for the development of cross-species anti-coronavirus therapeutics.
Low et al., COVID-19 Therapeutic Potential of Natural Products, International Journal of Molecular Sciences, doi:10.3390/ijms24119589
Despite the fact that coronavirus disease 2019 (COVID-19) treatment and management are now considerably regulated, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still one of the leading causes of death in 2022. The availability of COVID-19 vaccines, FDA-approved antivirals, and monoclonal antibodies in low-income countries still poses an issue to be addressed. Natural products, particularly traditional Chinese medicines (TCMs) and medicinal plant extracts (or their active component), have challenged the dominance of drug repurposing and synthetic compound libraries in COVID-19 therapeutics. Their abundant resources and excellent antiviral performance make natural products a relatively cheap and readily available alternative for COVID-19 therapeutics. Here, we deliberately review the anti-SARS-CoV-2 mechanisms of the natural products, their potency (pharmacological profiles), and application strategies for COVID-19 intervention. In light of their advantages, this review is intended to acknowledge the potential of natural products as COVID-19 therapeutic candidates.
