A review on quality control, toxicity and clinical application of Amomum tsao-ko Crevost & Lemarie

The dried fruit of Amomum tsao-ko Crevost & Lemarie, a perennial herb of Cardamom in Zingiberaceae, has been widely used in food and as a folk medicine. It is used not only as an important food additive and spice for removing peculiar smell and improving taste, but also as a traditional Chinese medicine with significant efficacy in treating many kinds of disorders. Based on the high edible and medicinal value, large amounts of investigation have been reported for A. tsaoko in the past several years. This review specifically summarises its quality control, toxicology and clinical application, about which no literature had systematically reviewed, based on our best acknowledge. The current quality control of A. tsaoko is based on the content of volatile oil, which should be no less than 1.4% according to the Pharmacopoeia of the People's Republic of China (2020 edition), while a more possible Q-Markers should be developed to focus on either a specific bioactive ingredient or a component correlated with a certain clinical efficacy. Toxicity research suggests that A. tsaoko actually belongs to the non-toxic substance, although citral and 1,8-cineole, two main components of A. tsaoko, is hepatotoxic for the former and displays low acute toxicity and sub-chronic oral toxicity for the latter, but no obviously accumulative toxicity has so far been discovered for A. tsaoko. In clinical practice, A. tsaoko is often used in treatment of dampness/cold resistance, malaria, vomiting, fullness and epigastric distension across additional disorders, such as SARS, COVID-19 and hepatitis.Copyright © 2022 The Author(s)

Jing Si Herbal Drink as a prospective adjunctive therapy for COVID-19 treatment: Molecular evidence and mechanisms

Background: SARS-CoV-2 has led to a sharp increase in the number of hospitalizations and deaths from pneumonia and multiorgan disease worldwide;therefore, SARS-CoV-2 has become a global health problem. Supportive therapies remain the mainstay treatments against COVID-19, such as oxygen inhalation, antiviral drugs, and antibiotics. Traditional Chinese medicine (TCM) has been shown clinically to relieve the symptoms of COVID-19 infection, and TCMs can affect the pathogenesis of SARS-CoV-2 infection in vitro. Jing Si Herbal Drink (JSHD), an eight herb formula jointly developed by Tzu Chi University and Tzu Chi Hospital, has shown potential as an adjuvant treatment for COVID-19 infection. A randomized controlled trial (RCT) of JSHD as an adjuvant treatment in patients with COVID-19 infection is underway Objectives: This article aims to explore the efficacy of the herbs in JSHD against COVID-19 infection from a mechanistic standpoint and provide a reference for the rational utilization of JSHD in the treatment of COVID-19. Method(s): We compiled evidence of the herbs in JSHD to treat COVID-19 in vivo and in vitro. Result(s): We described the efficacy and mechanism of action of the active ingredients in JSHD to treat COVID-19 based on experimental evidence. JSHD includes 5 antiviral herbs, 7 antioxidant herbs, and 7 anti-inflammatory herbs. In addition, 2 herbs inhibit the overactive immune system, 1 herb reduces cell apoptosis, and 1 herb possesses antithrombotic ability. Conclusion(s): Although experimental data have confirmed that the ingredients in JSHD are effective against COVID-19, more rigorously designed studies are required to confirm the efficacy and safety of JSHD as a COVID-19 treatment.Copyright © 2021

Screening of Natural Antivirals Against the COVID-19 Pandemic-A Compilation of Updates

Coronavirus disease 2019 (COVID-19), named by WHO, is a real public health disaster of the third millennium. This highly contagious viral disease has infected the world population and is now a global pandemic. This acute respiratory distress syndrome (ARDS) has severe complica-tions like pneumonitis, respiratory failure, shock, multiorgan failure, and death. Well-defined FDA-approved synthetic is not yet available. Case management strategies like lockdown, use of masks and sanitizers, social distancing, and repurposing of antiviral drugs were initially undertaken to cope with this pandemic. Different broad-spectrum antiviral drugs are being repurposed as one of the treatment modalities. The global vaccination programme with the newly launched COVID-19 vac-cines, Covishield, covaxin, sputnik V, etc., is an ongoing process. Simultaneously, significant research is being carried out in search of natural antivirals and evaluating the potency of food bioac-tives to aid naturistic protection against the coronavirus. This mini-review has compiled the latest updates on the screening and evidence-based mechanistic evaluation of phytochemicals and food bioactives as non-pharmacological adjuvant aid in COVID pandemics.Copyright © 2023 Bentham Science Publishers.

Known *Anti Sars-Cov Protease Inhibitors* On Sars-Cov-2 Related Intracellular Reception Sites: *Docking Interaction* And Computer Aided Optimization Of Molecular Structure For *Chemioselective Interactions*

Molecular docking and molecular dynamics aided virtual search of OliveNet™ directory identified potential secoiridoids that combat SARS-CoV-2 entry, replication, and associated hyperinflammatory responses. OliveNet™ is an active directory of phytochemicals obtained from different parts of the olive tree, Olea europaea (Oleaceae). Olive oil, olive fruits containing phenolics, known for their health benefits, are indispensable in the Mediterranean and Arabian diets. Secoiridoids is the largest group of olive phenols and is exclusive to the olive fruits. Functional food like olive fruits could help prevent and alleviate viral disease at an affordable cost. A systematized virtual search of 932 conformers of 78 secoiridoids utilizing Autodock Vina, followed by precision docking using Idock and Smina indicated that Nüzhenide oleoside (NZO), Oleuropein dimer (OED), and Dihydro oleuropein (DHO) blocked the SARSCoV-2 spike (S) protein-ACE-2 interface;Demethyloleuropein (DMO), Neo-nüzhenide (NNZ), and Nüzhenide (NZE) blocked the SARS-CoV-2 main protease (Mpro). Molecular dynamics (MD) simulation of the NZO-S-protein-ACE-2 complex by Desmond revealed stability during 50 ns. RMSD of the NZO-S-protein-ACE-2 complex converged at 2.1 Å after 20 ns. During MD, the interaction fractions confirmed multiple interactions of NZO with Lys417, a crucial residue for inhibition of S protein. MD of DMO-Mpro complex proved its stability as the RMSD converged at 1.6 Å. Analysis of interactions during MD confirmed the interaction of Cys145 of Mpro with DMO and, thus, its inhibition. The docking predicted IC50 of NZO and DMO was 11.58 and 6.44 μM, respectively. Molecular docking and dynamics of inhibition of the S protein and Mpro by NZO and DMO correlated well. Docking of the six-hit secoiridoids to IL1R, IL6R, and TNFR1, the receptors of inflammatory cytokines IL1β, IL6, and TNFα, revealed the anti-inflammatory potential except for DHO. Due to intricate structures, the secoiridoids violated Lipinski's rule of five. However, the drug scores of secoiridoids supported their use as drugs. The ADMET predictions implied that the secoiridoids are non-toxic and pose low oral absorption. Secoiridoids need further optimization and are a suitable lead for the discovery of anti-SARS-CoV-2 therapeutics. For the moment, olive secoiridoids presents an accessible mode of prevention and therapy of SARS-CoV-2 infection.
