ABSTRACT

Withania somnifera (L.) Dunal belongs to the nightshade family Solanaceae and is commonly known as Ashwagandha. It is pharmacologically a significant medicinal plant of the Indian sub-continent, used in Ayurvedic and indigenous systems of medicine for more than 3,000 years. It is a rich reservoir of pharmaceutically bioactive constituents known as withanolides (a group of 300 naturally occurring C-28 steroidal lactones with an ergostane-based skeleton). Most of the biological activities of W. somnifera have been attributed to two key withanolides, namely, withaferin-A and withanolide-D. In addition, bioactive constituents such as withanosides, sitoindosides, steroidal lactones, and alkaloids are also present with a broad spectrum of therapeutic potential. Several research groups worldwide have discovered various molecular targets of W. somnifera, such as inhibiting the activation of nuclear factor kappa-B and promoting apoptosis of cancer cells. It also enhances dopaminergic D2 receptor activity (relief in Parkinson's disease). The active principles such as sitoindosides VII-X and withaferin-A possess free radical properties. Withanolide-D increases the radio sensitivity of human cancer cells via inhibiting deoxyribonucleic acid (DNA) damage to non-homologous end-joining repair (NHEJ) pathways. Withanolide-V may serve as a potential inhibitor against the main protease (Mpro) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to combat COVID. The molecular docking studies revealed that the withanolide-A inhibits acetyl-cholinesterase in the brain, which could be a potential drug to treat Alzheimer's disease. Besides, withanolide-A reduces the expression of the N-methyl-D-aspartate (NMDA) receptor, which is responsible for memory loss in epileptic rats. This review demonstrates that W. somnifera is a rich source of withanolides and other bioactive constituents, which can be used as a safe drug for various chronic diseases due to the minimal side effects in various pre-clinical studies. These results are interesting and signify that more clinical trials should be conducted to prove the efficacy and other potential therapeutic effects in human settings.

ABSTRACT

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)

ABSTRACT

SARS-CoV-2 is continually evolving with the emergence of new variants with increased viral pathogenicity. The emergence of heavily mutated Omicron (B.1.1.529) with spike protein mutations are known to mediate its higher transmissibility and immune escape that has brought newer challenges for global public health to contain SARS-CoV-2 infection. One has to come up with a therapeutic strategy against the virus so as to effectively contain the infection and spread. Natural phytochemicals are being considered a significant source of bioactive compounds possessing an antiviral therapeutic potential. Being a promising anticancer and chemo-preventive agent, Silybin holds a significant potential to be used as a therapeutic. In the present study, molecular docking of Silybin with Omicron spike protein (7QNW) was carried out. Molecular docking results showed greater stability of Silybin in the active site of the Omicron spike protein with suitable binding mode of interactions. The study reveals that Silybin has the potential to block the host ACE2 receptor-viral spike protein binding;thereby inhibiting the viral entry to human cells. Therefore, Silybin may be further developed as a medication with the ability to effectively combat SARS-CoV-2 Omicron.Copyright © The Author(s) 2023.

ABSTRACT

Mimusops elengi Linn. Secondary metabolites of flavonoids, phenolic acids, coumarin classes and stilbene were identified by UPLC/ESI-QTOF-HRMS/MS technique with negative ion detection. Major Mimusops elengi flavonoids included Myricitrin, Myricetin, and Kaempferol-3-O-alpha-L-rhamnoside. The most abundant Coumarin and phenolic acids detected in the chromatogram included aesculin and quinic acid respectively. Down regulation of NLRP3 inflammasome activation inhibits the severe inflammatory responses caused by virus infection. Studying in silicobinding affinity of flavonoids, coumarins and phenolic acid in M. elengi leaves extract against the ADP binding site of NLRP3 protein (PDB code: 6NPY) demonstrated that investigated compounds have docking scores ranged from −6.20 to −12.30 kcal/mol. The best score was achieved by kaempferol-3-O-(6-p-coumaroyl) -glucoside(Compound 9) followed by aesculin (Compound 25) while Quinic acid (Compound 20) showed the lowest affinity toward ADP-binding site of NLRP3. © 2023 The Authors

ABSTRACT

Laurus nobilis (bay laurel) is a natural source of biological compounds, and some of its extracts and phytocompounds are also endowed with antiviral activity toward the family of the severe acute respiratory syndrome (SARS)-associated ß-coronaviruses. Some glycosidic laurel compounds such as laurusides were proposed as inhibitors of important protein targets of SARS-CoV-2, which clearly recalls their potential as anti-COVID-19 drugs. Due to the frequent genomic variations of the ß-coronaviruses and the consequent importance of evaluating a new drug candidate with respect to the variants of the target ß-coronavirus, we decided to investigate at an atomistic level the molecular interactions of the potential laurel-derived drugs laurusides 1 and 2 (L01 and L02, respectively) toward a well-conserved and crucial target, the 3C-like protease (Mpro), using the enzymes of both the wild-type of SARS-CoV-2 and of the more recent Omicron variant. Thus, we performed molecular dynamic (MD) simulations of laurusides-SARS-CoV-2 protease complexes to deepen the knowledge on the stability of the interaction and compare the effects of the targeting among the two genomic variants. We found that the Omicron mutation does not significantly impact the lauruside binding and that L02 connects more stably with respect to L01 in the complexes from both variants, even though both compounds prevalently interact within the same binding pocket. Although purely in silico, the current study highlights the potential role of bay laurel phytocompounds in the antiviral and specifically anti-coronavirus research and shows their potential binding toward Mpro, corroborating the important commitment of bay laurel as functional food and disclosing novel scenarios of lauruside-based antiviral therapies.

ABSTRACT

Ephedrae Herba (Ephedra), known as "MaHuang" in China, is the dried straw stem that is associated with the lung and urinary bladder meridians. At present, more than 60 species of Ephedra plants have been identified, which contain more than 100 compounds, including alkaloids, flavonoids, tannins, sugars, and organic phenolic acids. This herb has long been used to treat asthma, liver disease, skin disease, and other diseases, and has shown unique efficacy in the treatment of COVID-19 infection. Because alkaloids are the main components causing toxicity, the safety of Ephedra must be considered. However, the nonalkaloid components of Ephedra can be effectively used to replace ephedrine extracts to treat some diseases, and reasonable use can ensure the safety of Ephedra. We reviewed the phytochemistry, pharmacology, clinical application, and alkaloid toxicity of Ephedra, and describe prospects for its future development to facilitate the development of Ephedra.

ABSTRACT

Syzygium aromaticum (L.) Merril. & Perry commonly known as clove is an important herb with vast health benefits to human beings. S. aromaticum belongs to the Myrtaceae family and is considered one of the earliest known species for use as a spice. Clove has great potential for agricultural, cosmetic, food, and pharmaceutical applications. S. aromaticum extracts are commonly used to provide aroma, medicinal, nutritional, texture, and color functions in food products. They are light yellow to orange in color, have a pleasant aroma, and are considered a carbohydrate, dietary fiber, protein, and fat source. In addition, cloves are used to preserve food by inhibiting the growth of a wide range of pathogenic microorganisms, such as Listeria monocytogenes, Streptococcus agalactiae, and Penicillium digitatum, which cause foodborne illnesses and food poisoning. Furthermore, S. aromaticum extracts contain a diverse array of secondary metabolites, like flavonoids, hydroxybenzoic acids, hydroxycinnamic acids, hydroxyphenyl propenes, eugenol, eugenol acetate, and gallic acid, with a wide range of beneficial health-promoting activities. These metabolites have active biological properties and unique aromatic structures and are safe for use in food and medicinal applications. Clove metabolites are considered as new beneficial natural antimicrobial agents to potentially combat cytotoxin genes-producing drug-resistant Helicobacter pylori, gastrointestinal disorders, anti-inflammatory, antithrombotic, antidiabetic, anesthetic, and possess insect-repellent properties. In addition, clove has been proven to have insulin-like biological activity and regulate energy metabolism. This chapter gives insights into the effects of clove extracts on health promotion and their potential applications. © 2022 Elsevier Inc. All rights reserved.

ABSTRACT

Coronavirus disease (COVID-19). caused by SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus-2), has been the cause of global pandemic and a matter of concern for a larger population on this planet. Despite recent reports of substantial research towards the development of viable therapies to combat this global health issue, there is still no approved therapy to cure SARS-CoV-2. India is witnessing a third wave of coronavirus (due to Omicron variant), with daily rise in COVID-19 cases in the states with large population may rise exponentially and lead to community transfer. The rapid mutations of the virus and never-ending new strains (Delta, Omicron) have now become more critical and it is hard to tell, how this situation will manifest in future. The increase in COVID-19 cases has put a pressure on the healthcare system, leading to uncertainty in the minds of the people. Indian systems of traditional medicines-AYUSH have a wide-ranging potential for being used in these tough times either as adjuvant therapy or prophylactically due to their age-old use in the community, classical references/text, pharmacopeias and scientific evidence about their safety and clinical efficacy. AYUSH-Unani (Greco-Arabian medicine) originated with the concept and teachings of Hippocrates and developed during the middle ages, which employs natural drugs of plant, animal and mineral origin for the treatment during the epidemic. An attempt has been made to give a brief overview on AYUSH-Unani concept of epidemic and its preventive measures by the use of single plant origin drugs/compound formulations, having pharmacological activities.

ABSTRACT

Curcumae Longae Rhizoma (CLR) is the rhizome of Curcuma longa L. Pharmacological studies show that CLR can be used to treat cervical cancer, lung cancer, lupus nephritis, and other conditions. In this paper, we review botany, traditional application, phytochemistry, pharmacological activity, and pharmacokinetics of CLR. The literature from 1981 to date was entirely collected from online databases, such as Web of Science, Google Scholar, China Academic Journals full-text database (CNKI), Wiley, Springer, PubMed, and ScienceDirect. The data were also obtained from ancient books, theses and dissertations, and Flora Reipublicae Popularis Sinicae. There are a total of 275 compounds that have been isolated from CLR, including phenolic compounds, volatile oils, and others. The therapeutic effect of turmeric has been expanded from breaking blood and activating qi in the traditional sense to antitumor, anti-inflammatory, antioxidation, neuroprotection, antibacterial, hypolipidemic effects, and other benefits. However, the active ingredients and mechanisms of action related to relieving disease remain ill defined, which requires more in-depth research and verification at a clinical level.

ABSTRACT

The SARS-COV-2 pandemic is causing mayhem on people all over the world. Although, immunization is progressing quickly, its effectiveness against new variants is unknown. The virus has proven to be exceedingly resistant to treatments, and no drugs have been demonstrated to be totally effective against SARS-COV-2 antiviral. However, a few vaccines have been produced, but best option for now is to adopt preventive steps for now and future as well. In general, the use of herbs is emerging as the best ploy among all preventive measures to enhance the immunity as they have great antiviral potential and antioxidant properties. Bryophytes especially (liverworts) are well known to contain a variety of potentially beneficial compounds such as terpenoids, quinones, phenylpropanoids, flavonoids, etc. In recent past, different liverwort extracts and isolated chemicals have demonstrated antibacterial, antiviral, and cytotoxic effects;highlighting the potential of liverworts as herbal treatments and chemical manufacture for application in a variety of goods. However, due to their small size, difficulties in collection, and identification, the bulk of liverworts remain unknown, particularly in India. In this light, an attempt has been made to screen a commonly growing liverwort, Plagiochasma rupestre (J.R. Forst. and G. Forst.) Steph. has been evaluated for its phytochemical profile and bioactivity.
