[PMID: 35228783 PMCID: PMC8866077 DOI: 10.1016/j.jaim.2022.100559] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 02/12/2022] [Accepted: 02/12/2022] [Indexed: 11/22/2022] Open
Abstract
Objectives This study was conducted to evaluate the efficacy and safety of Cap. Torchnil & Tab. Febcin when given as add-on therapy to Covid19 positive patients with moderate disease. Material and methods Following written informed consent, patients were randomized to receive Cap. Torchnil & Tab. Febcin in addition to standard of care (SOC) [Add-on Group] or only SOC [SOC Group] for 14 days. Effect on clinical symptoms, WHO Clinical Assessment scale, hospital stay duration, time to Covid negative report, Sp02 levels and biomarkers was assessed during admission and relapse rate, if any, post discharge for 3 months. Results 193 patients were screened and 150 completed the study, 77 in Add-on Group and 73 in SOC Group. Improvement in Covid related symptoms, WHO Assessment scale, time to covid negative report and duration of hospital stay was observed earlier in Add-on Group. Statistically significant fall in biomarker levels viz. CPK, D-dimer and IL-6 values at Day 14 and LDH levels at Days 7 & 14 was observed in Add-on Group. Improvement in Sp02 levels was also seen earlier in Add-on Group. Only 2 patients complained of acidity. Post discharge, 91 patients (49 from Add-on group and 42 from SOC group) came for physical visits. All these patients were clinically stable with no evidence of relapse. Conclusion The study results thus showed that Cap. Torchnil and Tab. Febcin were effective and safe when given as add-on therapy to SOC in the clinical management of patients with moderate Covid-19 disease.

TLC-Based Metabolite Profiling and Bioactivity-Based Scientific Validation for Use of Water Extracts in AYUSH Formulations. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2021:2847440. [PMID: 35003294 PMCID: PMC8741349 DOI: 10.1155/2021/2847440] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Revised: 11/16/2021] [Accepted: 12/14/2021] [Indexed: 11/20/2022]
Abstract
We aimed to develop a chromatographic method for scientific validation of water extract of some important Indian traditional plants used in AYUSH-based formulation as immunomodulator and to evaluate their bioactive potential. Fruits of Phyllanthus emblica L. and Piper nigrum L., stem of Tinospora cordifolia (Willd.) Miers, rhizome of Curcuma longa L., leaves of Ocimum sanctum L. and Achillea millefolium L., roots of Withania somnifera L., and stem bark of Azadirachta indica A. Juss. were coarsely powdered and extracted in three different solvents (water, ethanol, and hydroethanol). The antioxidant potential was determined through 1, 1-diphenyl-2-picrylhydrazyl and ferric reducing capacity methods. Thin-layer chromatography (TLC) was carried out for the comparative metabolite profiling of the extracts using toluene, ethyl acetate, and formic acid (5 : 4 : 1, v/v/v) as a solvent system. In vitro immunomodulatory activity of the extracts has been tested on splenocyte proliferation and pinocytic assay. Hydroethanolic extract (HEE) of most of the plant materials has the highest phenolic and flavonoid contents, followed by water extract (WE) and ethanolic extract (EE), whereas the water extracts of most of the plant material showed better antioxidant activity. Almost all extract exhibited splenocyte proliferation and pinocytic activity in a dose-dependent manner. But water extract showed significantly higher splenocyte proliferation and pinocytic activity as compared to the other two extracts. TLC analysis resulted in detection of totally 63 and 56 metabolites at 254 nm and 366 nm, respectively. Through principal component analysis (PCA), it was observed that metabolite pattern of different extracts from same plant materials may be different or similar. This preliminary result can be used for quality evaluation and to develop a synergy-based polyherbal combination of water extracts of selected plant materials.

[PMID: 36762008 PMCID: PMC9849013 DOI: 10.3897/phytokeys.205.82300] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Accepted: 07/18/2022] [Indexed: 05/21/2023]
Abstract
A recent molecular phylogenetic analysis of the Caesalpinia group demonstrated that it comprises 26 genera, but the recognition of a putative 27th genus, Ticanto, remained in doubt. This study presents a phylogenetic analysis of ITS and five plastid loci revealing a robustly supported monophyletic group representing the Ticanto clade, sister to the morphologically distinct genus Pterolobium. Based upon this evidence, along with a morphological evaluation, the genus Ticanto is here reinstated. Descriptions are provided for all nine species of Ticanto, together with a key to the species, maps, and colour photographs. Nine new combinations are made: Ticantocaesia (Hand.-Mazz.) R. Clark & Gagnon, T.crista (L.) R. Clark & Gagnon, T.elliptifolia (S. J. Li, Z. Y. Chen & D. X. Zhang) R. Clark & Gagnon, T.magnifoliolata (Metcalf) R. Clark & Gagnon, T.rhombifolia R. Clark & Gagnon, T.sinensis (Hemsl.) R. Clark & Gagnon, T.szechuenensis (Craib) R. Clark & Gagnon, T.vernalis (Champion ex Benth.) R. Clark & Gagnon and T.yunnanensis (S. J. Li, D. X. Zhang & Z.Y. Chen) R. Clark & Gagnon. The final major question in the delimitation of segregate genera from within Caesalpinia sensu lato and the Caesalpinia group is thus resolved.

Abstract
Objective Alternative medicine plays an important role today in searching for therapeutics for cancer and viral infection. So, a scientific validation to characterize constituents in the alternative medicines and therapeutic testing is warranted using modern instrumentation. Methods In the present study, an old herbomineral formulation, KanthaRasavillai [KRV], was characterized using UV-vis spectrometry, FT-IR, XRD, SEM, and TEM study. Also, In vitro and in vivo studies were done to evaluate their antiviral and anticancer activity. FT-IR and XRD studies revealed a cocktail of nanoparticles of mercury, magnetic oxide, cinnabar, and arsenic.Results.Based on SEM, TEM, and XRD report, KRV contains nanoparticles in the size range of 9.1 nm to 25.0 nm. FT-IR analysis exposed the presence of several anti-cancerous bioactive compounds.Further in vitro testing against HCV virus proved KRV to inhibit HCV virus a close relative to SARS-CoV-2. MTT assay confirmed the anticancer effect of KRV against Huh-7 and MCF-7 cell lines. Conclusion The anticancer and antiviral properties in the ancient herbomineral drug with a cocktail of metal nanoparticles acknowledge the traditional medical practice as a pioneering approach for present-day ailments. However, the study concludes that the use of KRV depends on safety dosage and genuine preparation as described by ancient saints.

Abstract
With the emergence of epidemics, pandemics, and infectious diseases, several research activities have been carried out on natural products to tackle them. As there are structural diversities in natural products, researchers are focused on exploring them for treatment and/or management of various infections and/or diseases. Acacia catechu (L.f.) Willd. belonging to the order Fabales and family Fabaceae shows a wide range of pharmacological functions in the management of diseases in humankind. This review was carried out to gather and provide information about the chemical constituents and pharmacological activities of A. catechu through the literature survey of scientific articles. On preliminary assessments, A. catechu is demonstrated as a significant wellspring of bioactive compounds with a wide range of biological and pharmaceutical applications such as antidiabetic, antioxidant, antimicrobial, anticancer, antidiarrheal, anti-inflammatory, antiviral, hepatoprotective, immunomodulatory, and so on. Although the metabolites from the plant are reported with diverse pharmacological applications, there is little information in regards to toxicity and clinical trials on bioactive compounds of this plant. Further research on diverse bioactive compounds from the plant is required to develop them as a successful potent drug.

Abstract
For the past 2 years, the coronavirus responsible for the COVID-19 infection has become a world pandemic, ruining the lives and economies of several nations in the world. This has scaled up research on the virus and the resulting infection with the goal of developing new vaccines and therapies. Natural products are known to be a rich source of lead compounds for drug discovery, including against infectious diseases caused by microbes (viruses, bacteria and fungi). In this review article, we conducted a literature survey aimed at identifying natural products with inhibitory concentrations against the coronaviruses or their target proteins, which lie below 10 µM. This led to the identification of 42 compounds belonging to the alkaloid, flavonoid, terpenoid, phenolic, xanthone and saponin classes. The cut off concentration of 10 µM was to limit the study to the most potent chemical entities, which could be developed into therapies against the viral infection to make a contribution towards limiting the spread of the disease.

Abstract
Coronavirus disease (COVID-19) has been declared as a pandemic by the World Health Organization with rapid spread across 216 countries. COVID-19 pandemic has left its imprints on various health systems globally and caused immense social and economic disruptions. The scientific community across the globe is in a quest for digging the effective treatment for COVID-19 and exploring potential leads from traditional systems of healthcare across the world too. Ayurveda (Indian traditional system of medicine) has a comprehensive aspect of immunity through Rasayana which is a rejuvenation therapy. Here we attempt to generate the potential leads based on the classical text from Ayurveda in general and Rasayana in particular to develop effective antiviral and/or immunomodulator for potential or adjunct therapy in SARS-CoV-2. The Rasayana acts not only by resisting body to restrain or withstand the strength, severity or progression of a disease but also by promoting power of the body to prevent the manifestation of a disease. These Rasayana herbs are common in practice as immunomodulator, antiviral and protectives. The studies on Rasayana can provide an insight into the future course of research for the plausible development of effective management of COVID-19 by the utilization and development of various traditional systems of healthcare. Keeping in view the current pandemic situation, there is an urgent need of developing potential medicines. This study proposes certain prominent medicinal plants which may be further studied for drug development process and also in clinical setup under repurposing of these herbs.

Abstract
Polyphenols are active substances against various types of viral infections. Researchers have characterized methods of how to isolate polyphenols without losing their potential to formulate pharmaceutical products. Researchers have also described mechanisms against common viral infections (i.e., influenza, herpes, hepatitis, rotavirus, coronavirus). Particular compounds have been discussed together with the plants in the biomass in which they occur. Quercetin, gallic acid and epigallocatechin are exemplary compounds that inhibit the growth cycle of viruses. Special attention has been paid to identify plants and polyphenols that can be efficient against coronavirus infections. It has been proven that polyphenols present in the diet and in pharmaceuticals protect us from viral infections and, in case of infection, support the healing process by various mechanisms, i.e., they block the entry into the host cells, inhibit the multiplication of the virus, seal blood vessels and protect against superinfection.

Abstract
BACKGROUND The burden of the COVID-19 pandemic in Peru has led to people seeking alternative treatments as preventives and treatment options such as medicinal plants. This study aimed to assess factors associated with the use of medicinal plants as preventive or treatment of respiratory symptom related to COVID-19 during the pandemic in Cusco, Peru. METHOD A web-based cross-sectional study was conducted on general public (20- to 70-year-old) from August 31 to September 20, 2020. Data were collected using a structured questionnaire via Google Forms, it consisted of an 11-item questionnaire that was developed and validated by expert judgment using Aiken's V (Aiken's V > 0.9). Both descriptive statistics and bivariate followed by multivariable logistic regression analyses were conducted to assess factors associated with the use of medicinal plants for COVID-19 prevention and respiratory symptom treatment during the pandemic. Prevalence ratios (PR) with 95% Confidence Interval (CI), and a P-value of 0.05 was used to determine statistical significance. RESULTS A total of 1,747 respondents participated in the study, 80.2% reported that they used medicinal plants as preventives, while 71% reported that they used them to treat respiratory symptoms. At least, 24% of respondents used medicinal plants when presenting with two or more respiratory symptoms, while at least 11% used plants for malaise. For treatment or prevention, the multivariate analysis showed that most respondents used eucalyptus (p < 0.001 for both), ginger (p < 0.022 for both), spiked pepper (p < 0.003 for both), garlic (p = 0.023 for prevention), and chamomile (p = 0.011 for treatment). The respondents with COVID-19 (p < 0.001), at older ages (p = 0.046), and with a family member or friend who had COVID-19 (p < 0.001) used more plants for prevention. However, the respondents with technical or higher education used less plants for treatment (p < 0.001). CONCLUSION There was a significant use of medicinal plants for both prevention and treatment, which was associated with several population characteristics and whether respondents had COVID-19.

Abstract
An outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) occurred in Wuhan, China, at the end of 2019. The World Health Organization named the resulting infectious disease as coronavirus disease-2019 (COVID-19). Many studies concluded that patients infected with SARS-CoV-2 have different degrees of liver disturbance. However, the relationship between the drugs used for COVID-19 treatment and liver disturbance remains controversial. It is essential to evaluate the potential liver damage caused by various drugs in order to help guide clinical practice. This review analyzed the effect of drugs on hepatic function during the treatment of COVID-19.

Abstract
Background: The coronavirus disease 2019 (COVID-19) pandemic has created a great burden on governments and the medical fraternity globally. Many clinical studies from the Indian system of Traditional Medicines [Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homoeopathy (AYUSH)] have been carried out to find appropriate solutions. Through a living systematic review and meta-analysis, this study aims to determine the effectiveness of the Traditional System of Indian Medicine (AYUSH system) in lowering the incidence, duration, and severity of COVID-19. Methods: We will search the following databases: Pubmed; the Cochrane central register of controlled trials (CENTRAL); the Clinical Trials Registry - India (CTRI); Digital Helpline for Ayurveda Research Articles (DHARA): AYUSH research portal; and World Health Organization (WHO) COVID-19 database. Clinical improvement, WHO ordinal scale, viral clearance, incidences of COVID-19 infection, and mortality will be considered as primary outcomes. Secondary outcomes will be use of O2 therapy or mechanical ventilator, admission to high dependency unit or emergency unit, duration of hospitalization, the time to symptom resolution, and adverse events. Two authors will independently search the articles, extract the data and disagreements will be resolved by the involvement of a third reviewer. Data will be synthesized, and the risk of bias will be assessed with RevMan 5.4 tool. Certainty of evidence will be assessed through the GRADE (Grading of Recommendations, Assessment, Development and Evaluations) tool. The review will be updated bi-monthly with two updates. Conclusion: This living systematic review will be the first to address AYUSH interventions in COVID-19, synthesizing the full spectrum of Indian Traditional System of Medicine against COVID-19. It will facilitate professionals, guideline developers, and authorities with up to date synthesis on interventions periodically to make health-care decisions on AYUSH therapies in the management of COVID-19.

Abstract
Abstract The Up-and-Coming-Scientist section of the current issue of the Journal of Membrane Biology features the invited essay by Dr. Mercedes Alfonso-Prieto, Assistant Professor at the Forschungszentrum Jülich (FZJ), Germany, and the Heinrich-Heine University Düsseldorf, Vogt Institute for Brain Research.
Dr. Alfonso-Prieto completed her doctoral degree in chemistry at the Barcelona Science Park, Spain, in 2009, pursued post-doctoral research in computational molecular sciences at Temple University, USA, and then, as a Marie Curie post-doctoral fellow at the University of Barcelona, worked on computations of enzyme reactions and modeling of photoswitchable ligands targeting neuronal receptors. In 2016, she joined the Institute for Advanced Science and the Institute for Computational Biomedicine at the FZJ, where she pursues research on modeling and simulation of chemical senses.
The invited essay by Dr. Alfonso-Prieto discusses state-of-the-art modeling of molecular receptors involved in chemical sensing – the senses of taste and smell. These receptors, and computational methods to study them, are the focus of Dr. Alfonso-Prieto’s research. Recently, Dr. Alfonso-Prieto and colleagues have presented a new methodology to predict ligand binding poses for GPCRs, and extensive computations that deciphered the ligand selectivity determinants of bitter taste receptors. These developments inform our current understanding of how taste occurs at the molecular level. Graphic Abstract ![]()

Mohan PK, Adarsh Krishna TP, Senthil Kumar T, Ranjitha Kumari BD. Pharmaco-chemical profiling of Desmodium gangeticum (L.) DC. with special reference to soil chemistry. FUTURE JOURNAL OF PHARMACEUTICAL SCIENCES 2021; 7:210. [PMID: 34692854 PMCID: PMC8520758 DOI: 10.1186/s43094-021-00356-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Accepted: 10/05/2021] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Desmodium gangeticum (L.) DC. (Fabaceae) (DG) is a perennial non-climbing herb or shrub and folklore medicine, widely shows a large number of medicinal properties, as well as contains divergent bioactive compounds. Many of the herbal formulations contain this medicinal plant, which is considered as master of medicinal plant in Ayurveda. This study is an attempt to establish this plant material based on its pharmaco-chemical profiles with special reference to soil chemistry. The pharmaco-chemical features such as organoleptic, DNA sequence, physicochemical, proximate, phytochemical, UV, and FTIR profiling were carried out using standard techniques. Moreover, the ADME-PK properties of the selected molecules were established. RESULTS The pharmaco-chemical features like organoleptic, DNA sequence, physicochemical, proximate, phytochemical, UV, and FTIR profiling, ADME-PK properties, and soil chemistry of D. gangeticum revealed its unique and diagnostic peculiarities. DNA barcoding showed that the sequence was 99.77% similar to D. gangeticum (KP094638) having 100% query coverage. The soil analysis revealed the presence of moderately high content of NPK and sufficient amount of all essential macro- and micronutrients (S, Fe, Mn, Cu, Zn, and B). The phytochemical profiling showed that the ethanolic extract of the aerial part contained glycoside, amino acid, phenols, alkaloids, flavonoids, and coumarins, while the ethanolic root extract of the plant revealed the presence of glycoside, amino acid, phenols, alkaloids, flavonoids, coumarins, and triterpenoids. FTIR results indicated that the plant extracts are mainly rich in phenolic derivatives. ADME-PK properties of pterocarpan such as gangetin (1a), gangetinin (1b), desmocarpin (1c), and desmodin (1d) were found to pass the Lipinski, Ghose, Veber, and Egan rules, supporting the drug-likeliness. CONCLUSION This is the first record of pharmaco-chemical profiling of D. gangeticum along with soil chemistry, and this information helps in the proper identification and future studies on this species.
