Evaluating therapeutic potential of AYUSH-64 constituents against omicron variant of SARS-CoV-2 using ensemble docking and simulations. Curr Res Struct Biol 2024; 7:100151. [PMID: 38881558 PMCID: PMC11179622 DOI: 10.1016/j.crstbi.2024.100151] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Revised: 05/07/2024] [Accepted: 05/27/2024] [Indexed: 06/18/2024] Open
Abstract
The COVID-19 pandemic in the later phase showed the presence of the B.1.1.529 variant of the SARS-CoV-2 designated as Omicron. AYUSH-64 a poly herbal drug developed by Central Council for Research in Ayurvedic Sciences (CCRAS) has been recommended by Ministry of Ayush in asymptomatic, mild to moderate COVID-19 patients. One of the earlier, in-silico study has shown the binding of the constituents of AYUSH-64 to the main protease (Mpro) of the SARS-CoV-2. This study enlisted four phytochemicals of AYUSH-64, which were found to have significant binding with the Mpro. In continuation to the same, the current study proposes to understand the binding of these four phytochemicals to main protease (Mpro) and receptor binding domain (RBD) of spike protein of the Omicron variant. An enhanced molecular docking methodology, namely, ensemble docking has been used to find the most efficiently binding phytochemical. Using molecular dynamics (MD) simulations and clustering approach it was observed that the Mpro and RBD Spike of Omicron variant of SARS-CoV-2 in complex with human ACE2 tends to attain 4 and 8 conformational respectively. Based on the docking studies, the best binding phytochemical of the AYUSH-64, akummicine N-oxide was selected for MD simulations. MD simulations of akummicine N-oxide bound to omicron variant of Mpro and RBD Spike-ACE complex was performed. The conformational, interaction and binding energy analysis suggested that the akummicine N-oxide binds well with Mpro and RBD Spike-ACE2 complex. The interaction between RBD Spike and ACE2 was observed to weaken in the presence of akummicine N-oxide. Hence, it can be inferred that, these phytochemicals from AYUSH-64 formulation may have the potential to act against the Omicron variant of SARS-CoV-2.

Effect of Yoga-based breathing practices on depression, anxiety, stress, and fear of COVID-19 positive hospitalized patients: A randomized controlled trial. J Ayurveda Integr Med 2024; 15:100897. [PMID: 38527392 PMCID: PMC10982563 DOI: 10.1016/j.jaim.2024.100897] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2023] [Revised: 01/18/2024] [Accepted: 01/30/2024] [Indexed: 03/27/2024] Open
Abstract
BACKGROUND COVID-19 infection has an impact on the mental state of patients and requires attention to mental health care. OBJECTIVE The aim of this study is to assess the effect of Yoga-based breathing practices on the mental state of patients with COVID-19. MATERIAL AND METHODS A randomized controlled trial was conducted with63 patients (male=46) who were RT-PCR positive for COVID-19 and hospitalized with asymptomatic (RT-PCR positive but no symptoms), mild (febrile, body ache, pharyngitis, nonproductive cough), and moderate (SpO2< 92%) symptoms assigned in the yoga (n=32) and control group (n=31). The study was conducted at Atharva Multispecialty Hospital and Research Center, North India. The yoga group received Yoga-based breathing practices twice a day for ten days in addition to conventional care, and the control group was advised not to do the practice. The Depression Anxiety and Stress scale (DASS-21) and fear of COVID-19 were assessed at baseline and after 10 days. Repeated measures ANOVA with Bonferroni correction was used to assess between and within subjects' effects. RESULTS The experimental group had better scores for depression, anxiety, stress, total DASS scores, and fear of COVID-19 (p<0.001) when compared with the control group. Within the group, analyses demonstrated improved scores in all domains in the yoga group (p<0.001) by the end of the intervention. In contrast, the control group improved only in stress scores (p=0.002), total DASS scores (p=0.012), and fear of COVID-19 (p=0.039). There are no adverse effects seen with Yoga-based breathing practices in these patients. CONCLUSION Yoga-based breathing practices have been found to have positive impact on mental health among COVID-19-positive patients during hospitalization.

Evaluation of Ayush-64 (a Polyherbal Formulation) and Its Ingredients in the Syrian Hamster Model for SARS-CoV-2 Infection Reveals the Preventative Potential of Alstonia scholaris. Pharmaceuticals (Basel) 2023; 16:1333. [PMID: 37765142 PMCID: PMC10534577 DOI: 10.3390/ph16091333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 08/16/2023] [Accepted: 09/02/2023] [Indexed: 09/29/2023] Open
Abstract
In the current study, we evaluated the efficacy of Ayush-64 (A64), a polyherbal formulation containing Alstonia scholaris (L.) R. Br. (A. scholaris), Caesalpinia crista L. (C. crista), Picrorhiza kurroa Royle ex Benth (P. kurroa), and Swertia chirata (Roxb.) H. Karst. (S. chirata) against COVID-19 in a Syrian hamster infection model. Preventative use of A64 resulted in the late-phase recovery of body weight loss in severe acquired respiratory syndrome coronavirus-2 (SARS-CoV-2)-infected hamsters, suppression of pro-inflammatory cytokines, and blunted pulmonary pathology. In addition, we also investigated the efficacy of individual ingredients of A64, viz., A. scholaris, C. crista, P. kurroa, and S. chirata, in the hamster model. The hamster challenge data showed robust anti-viral and immunomodulatory potential in A. scholaris, followed by P. kurroa. However, C. crista and S. chirata of A64 showed prominent immunomodulatory potential without limiting the lung viral load. In order to better understand the immunomodulatory potential of these herbal extracts, we used an in vitro assay of helper T cell differentiation and found that A. scholaris mediated a more profound suppression of Th1, Th2, and Th17 cell differentiation as compared to A64 and other ingredients. Taken together, our animal study data identifies the ameliorative potential of A64 in mitigating coronavirus disease-19 (COVID-19) pulmonary pathology. A. scholaris, a constituent extract of A64, showed relatively higher anti-viral and immunomodulatory potential against COVID-19. The present study warrants further investigations to identify the active pharmaceutical ingredients of A. scholaris for further studies.

Abstract
The microbiome of the human gut is a complex assemblage of microorganisms that are in a symbiotic relationship with one another and profoundly influence every aspect of human health. According to converging evidence, the human gut is a nodal point for the physiological performance matrixes of the vital organs on several axes (i.e. gut-brain, gut-lung, etc). As a result of COVID-19, the importance of gut-lung dysbiosis (balance or imbalance) has been realised. In view of this, it is of utmost importance to develop a comprehensive understanding of the microbiome, as well as its dysbiosis. In this review, we provide an overview of the gut-lung axial microbiome and its importance in maintaining optimal health. Human populations have successfully adapted to geophysical conditions through traditional dietary practices from around the world. In this context, a section has been devoted to the traditional Indian system of medicine and its theories and practices regarding the maintenance of optimally customized gut health.

Abstract
The proteolytic enzyme 3 C-like protease (3Clpro or Mpro) is considered the most important target for SARS-CoV-2 which could be attributed to its crucial role in viral maturation and/or replication. Besides, natural phytoconstituents from plant origin are always promising lead compounds in the drug discovery area. Herein, the previously isolated and identified seven compounds from Jasminum humile (J. humile) were examined in vitro and in silico against the SARS-CoV-2 Mpro. First, the Vero E6 cells were utilized to pursue the potential of the investigated compounds (both in fractions and individual isolates) using the MTT assay. The total extract (T1) displayed the most significant activity against SARS-CoV-2 with IC50 = 29.36 µg/mL. Besides, the fractions (Fr1 and Fr3) showed good activity against the SARS-CoV-2 with IC50 values of 70.42, and 73.09 µg/mL, respectively. Then, the SARS-CoV-2 Mpro inhibitory assay was utilized to emphasize the inhibitory potential of the investigated isolates. MJN, JMD, and IJM candidates displayed prominent Mpro inhibitory potentials with IC50 = 30.44, 30.24, and 56.25 µM, respectively. Moreover, molecular docking of the identified seven compounds against the Mpro of SARS-CoV-2 showed that the five secoiridoids achieved superior results. MJN, JSM, IJM, and JMD showed higher affinities towards the Mpro target compared to the co-crystallized antagonist. Furthermore, the most active complexes (MJN, JSM, IJM, and JMD-Mpro) were subjected to MD simulations run for 150 ns and MM-GBSA calculations, compared to the co-crystallized inhibitor (O6K-Mpro). Finally, the SAR study clarified that JMD achieved the best anti-SARS-CoV-2 Mpro activity followed by MJN.Communicated by Ramaswamy H. Sarma.

Abstract
PURPOSE Juvenile myoclonic epilepsy (JME) is an adolescent onset type of idiopathic generalized epilepsies. Bromodomain containing protein-2 gene (BRD2), a transcriptional regulatory protein, has a susceptible role in the expression of JME. Considering the polymorphic variations observed in exon 3 of the BRD2 gene, we evaluated the molecular interactions with anti-seizure medication in individuals diagnosed with JME. METHODS The genomic DNA was extracted from 5 mL of peripheral venous blood of JME participants (n = 55) and healthy control subjects (n = 55). Detailed anti-seizure medication and outcomes were noted during the study period. Identified novel mutations at nucleotide and protein sequences, compared by multiple sequence alignment. Wild-type (WT) and mutated-type (MT) structures were investigated for molecular docking and interactions with anti-seizure drugs. RESULTS A common variant at c.1707G>A was found among 23 participants, while a single variant at c.1663ins C was found in one participant. The deletion positions were observed at c.1890delA, c.1892A>T, c.1895A>T, c.1896G>T, c.1897T>C, c.1898T>C, c.1899C>T, c.1900G>T, c.1901C>T and c.1902A>T exhibiting stop codon after p.111Pro>stop; these variants resulted in a truncated protein. In silico analysis was conducted to validate changes; docking analysis showed that novel variant has a significant role in the interactions with anti-seizure drugs. SIGNIFICANCE Besides clinical and genetic outcomes, ∼5.45% unique genetical variations were observed in the participants. Significant mimicked at the binding site position (92-111) of human BRD2 ranges ∼8.2%, ∼16.4%, and ∼10.6%. Further, research is needed to identify the importance of polymorphism alterations at the binding site and their molecular interactions with anti-seizure drugs, which might be confirmed in a diverse population with JME.

Abstract
OBJECTIVE Evaluate the efficacy of AYUSH 64, a standard polyherbal Ayurvedic drug in COVID-19. METHODS During the first pandemic wave, 140 consenting and eligible hospitalized adult participants with mild-moderate symptomatic disease (specific standard RT-PCR assay positive) were selected as per a convenience sample, and randomized (1:1 ratio) to an open-label (assessor blind) two-arm multicentric drug trial; standard of care (SOC as per Indian guidelines) versus AYUSH 64 combined with SOC (AYUSH plus). Participants were assessed daily and discharged once clinical recovery (CR, primary efficacy) was achieved which was based on a predetermined set of criteria (resolution of symptoms, normal peripheral oximetry, and negative specific RT-PCR assay). Each participant was followed using an indigenous software program(mobile phone) and completed a 12-week study period. The dose of AYUSH 64 was 2 tablets oral, 500 mg each, bid for 12 weeks (AYUSH plus only). Significant P was <0.05 (two-sided). On randomization, the groups were found well matched. RESULTS The mean interval time from randomization to CR was significantly superior in the AYUSH plus group [mean 6.45 days versus 8.26 days, 95% Confidence Interval of the difference -3.02 to -0.59 (P = 0.003, Student's 't test] as per-protocol analysis (134 participants); significant (P = 0.002) on an intention to treat analysis. 70% of the participants in AYUSH plus recovered during the first week (P = 0.046, Chi-square) and showed a significantly better change in physical health, fatigue, and quality of life measures. 48 adverse events, mostly mild and gut related, were reported by each group. There were 20 patient withdrawals (8 in AYUSH plus) but none due to an AE. There were no deaths. Daily assessment (hospitalization) and supervised drug intake ensured robust efficacy data. The open-label design was a concern (study outcome). CONCLUSIONS AYUSH 64 in combination with SOC hastened recovery, reduced hospitalization, and improved health in COVID-19. It was considered safe and well-tolerated. Further clinical validation (Phase III) is required. TRIAL REGISTRATION CTRI/2020/06/025557.

Abstract
Background: In India, alternative and complementary therapies (Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homeopathy [AYUSH] medicines) are extensively utilized in COVID-19 management, and some were investigated clinically. This study assessed the effectiveness of AYUSH therapeutic on COVID-19 through a living systematic review and meta-analysis approach. Methods: Databases like PubMed; the Cochrane central register of controlled trials; WHO COVID-19 database; the central trial registry-India; Digital Helpline for Ayurveda Research Articles and AYUSH research portal, and preprint repositories were searched till August 1, 2021. Randomized controlled trials or analytical observational studies were included only. Primary outcomes selected were clinical improvement, WHO ordinal scale, viral clearance, and mortality, whereas secondary outcomes were the 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. The risk of bias was evaluated by Version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB-2) and Risk of Bias in Nonrandomized Studies-of Interventions (ROBINS-I) tools; data were synthesized through RevMan 5.4 tool, and the certainty of the evidence was ranked through the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Results: Of 3609 studies retrieved, 17 were included in the systematic review, and 3 AYUSH therapeutics were meta-analyzed. Meta-analysis suggested that add-on AYUSH-64 likely provides therapeutic benefits by reducing time to symptom resolution (mean difference [MD] 2.35 days lower [95% confidence interval, CI; 4.05 lower to 0.65 lower]) and hastening clinical improvement (365 more per 1000 [95% CI; 4 more to 1000 more]) in mild-to-moderate COVID-19 patients. Kabasura Kudineer adjuvant to standard care is likely to reduce symptom resolution (MD; 1.93 days lower [95% CI; 2.28 lower to 1.58 lower]) and hospital stay (MD; 4.2 days lower [95% CI; 4.97 lower to 3.43 lower]) in mild-to-moderate COVID-19 patients. Co-administration of Guduchi (Tinospora cordifolia [Willd.] Miers.) to standard care may reduce the duration of hospitalization (MD; 3.93 days, lower [95% CI; 8.83 lower to 0.97 higher]) in mild-to-moderate COVID-19 patients. Furthermore, all three agents seemed safe in adjunct usage to standard care. The certainty of evidence for most outcomes was moderate to low, primarily due to the high risk of bias or imprecision owing to the small sample size. Conclusion: Rational use of integrated or standalone AYUSH interventions in mild-to-moderate COVID-19 patients is safe and may provide therapeutic benefits. The effect estimates may be changed with additional evidence in upcoming updates.

Abstract
The current study aims to develop a PAN India database of medicinal plants along with their phytochemicals and geographical availability. The database consists of 6959 unique medicinal plants belonging to 348 families which are available across 28 states and 8 union territories of India. The database sources the information on four different sections - traditional knowledge, geographical indications, phytochemicals, and chemoinformatics. The traditional knowledge reports the plant taxonomy with their vernacular names. A total of 27,440 unique phytochemicals associated with these plants were curated from various sources in this study. However, due to the non-availability of general information like IUPAC names, InChI key, etc. from reliable sources, only 22,314 phytochemicals have been currently reported in the database. Various analyses have been performed for the phytochemicals which include analysis of physicochemical and ADMET properties calculated from open-source web servers using in-house python scripts. The phytochemical data set has also been classified based on the class, superclass, and pathways respectively using NPClassifier, a deep learning framework. Additionally, the antiviral potency of the phytochemicals was also predicted using two machine learning models - Random Forest and XGBoost. The database aims to provide accurate and exhaustive data of the traditional practice of medicinal plants in India in a single platform integrating and analyzing the rich customary practices and facilitating the development and identification of plant-based therapeutics for a variety of diseases. The database can be accessed at https://neist.res.in/osadhi/.

Abstract
Ayurvedic medicines Withania somnifera Dunal (ashwagandha) and AYUSH-64 have been used for the prevention and management of COVID-19 in India. The present study explores the effect of Ashwagandha and AYUSH-64 on important human CYP enzymes (CYP3A4, CYP2C8, and CYP2D6) to assess their interaction with remdesivir, a drug used for COVID-19 management during the second wave. The study also implies possible herb−drug interactions as ashwagandha and AYUSH-64 are being used for managing various pathological conditions. Aqueous extracts of ashwagandha and AYUSH-64 were characterized using LC-MS/MS. A total of 11 and 24 phytoconstituents were identified putatively from ashwagandha and AYUSH-64 extracts, respectively. In addition, in silico studies revealed good ADME properties of most of the phytoconstituents of these herbal drugs and suggested that some of these might possess CYP-450 inhibitory activity. In vitro CYP-450 studies with human liver microsomes showed moderate inhibition of CYP3A4, 2C8, and 2D6 by remdesivir, while ashwagandha had no inhibitory effect alone or in combination with remdesivir. AYUSH-64 also exhibited a similar trend; however, a moderate inhibitory effect on CYP2C8 was noticed. Thus, ashwagandha seems to be safe to co-administer with the substrates of CYP3A4, CYP2C8, and CYP2D6. However, caution is warranted in prescribing AYUSH-64 along with CYP2C8 substrate drugs. Furthermore, preclinical and clinical PK studies would be helpful for their effective and safer use in the management of various ailments along with other drugs.

[PMID: 35841663 PMCID: PMC9259013 DOI: 10.1016/j.phymed.2022.154324] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Revised: 06/23/2022] [Accepted: 07/05/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND COVID-19 highly caused contagious infections and massive deaths worldwide as well as unprecedentedly disrupting global economies and societies, and the urgent development of new antiviral medications are required. Medicinal herbs are promising resources for the discovery of prophylactic candidate against COVID-19. Considerable amounts of experimental efforts have been made on vaccines and direct-acting antiviral agents (DAAs), but neither of them was fast and fully developed. PURPOSE This study examined the computational approaches that have played a significant role in drug discovery and development against COVID-19, and these computational methods and tools will be helpful for the discovery of lead compounds from phytochemicals and understanding the molecular mechanism of action of TCM in the prevention and control of the other diseases. METHODS A search conducting in scientific databases (PubMed, Science Direct, ResearchGate, Google Scholar, and Web of Science) found a total of 2172 articles, which were retrieved via web interface of the following websites. After applying some inclusion and exclusion criteria and full-text screening, only 292 articles were collected as eligible articles. RESULTS In this review, we highlight three main categories of computational approaches including structure-based, knowledge-mining (artificial intelligence) and network-based approaches. The most commonly used database, molecular docking tool, and MD simulation software include TCMSP, AutoDock Vina, and GROMACS, respectively. Network-based approaches were mainly provided to help readers understanding the complex mechanisms of multiple TCM ingredients, targets, diseases, and networks. CONCLUSION Computational approaches have been broadly applied to the research of phytochemicals and TCM against COVID-19, and played a significant role in drug discovery and development in terms of the financial and time saving.

Abstract
Background During the second wave of the COVID-19 pandemic in India, the Ministry of Ayush conducted a community study to provide therapeutic care to patients with asymptomatic, mild, and moderate COVID-19 in home isolation based on the empirical evidence generated on the efficacy of AYUSH-64 in COVID-19. Objective To document disease characteristics, care-seeking behavior, and outcomes in patients with asymptomatic, mild, or moderate COVID-19 in home isolation who used AYUSH-64 for COVID-19. Methods Cross-sectional analysis of the data generated through a community study conducted in India from 08 May to 31 August 2021 was performed to study the disease characteristics, care-seeking behavior during home isolation, clinical outcomes, adverse events, and the association between various risk factors and clinical recovery during the study period. The data were collected through semi-structured questionnaires, available in electronic data collection format at the baseline, 7, 14, and 21 days. A logistic regression was performed to explore the relationship between relevant variables and clinical recovery. Results Data from 64,642 participants were analyzed for baseline assessment, and final analysis was done for 49,770 participants. The mean age of the enrolled participants was 38.8 ± 11.7 years, and 8.4% had co-morbidities. AYUSH-64 was utilized as an add-on to the standard care by 58.3% of participants. Comparable clinical outcomes were observed in participants utilizing AYUSH-64 either as a standalone or as an add-on to standard care, in terms of clinical recovery, disease progression, the requirement for oxygen supplementation, hospitalization, ICU admission, and need for ventilator support. Younger age, having no co-morbidities or substance abuse, and having been vaccinated were associated with early clinical recovery than those who were older and not vaccinated. Conclusions The study findings suggest that AYUSH-64 use, either standalone or as an adjunct to standard care, in asymptomatic, mild, or moderate COVID-19 is associated with good clinical outcomes. Ayush services and interventions can be effectively integrated into the mainstream public health architecture to serve public health goals.

Abstract
Despite tremendous efforts in the past two years, our understanding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), virus-host interactions, immune response, virulence, transmission, and evolution is still very limited. This limitation calls for further in-depth investigation. Computational studies have become an indispensable component in combating coronavirus disease 2019 (COVID-19) due to their low cost, their efficiency, and the fact that they are free from safety and ethical constraints. Additionally, the mechanism that governs the global evolution and transmission of SARS-CoV-2 cannot be revealed from individual experiments and was discovered by integrating genotyping of massive viral sequences, biophysical modeling of protein-protein interactions, deep mutational data, deep learning, and advanced mathematics. There exists a tsunami of literature on the molecular modeling, simulations, and predictions of SARS-CoV-2 and related developments of drugs, vaccines, antibodies, and diagnostics. To provide readers with a quick update about this literature, we present a comprehensive and systematic methodology-centered review. Aspects such as molecular biophysics, bioinformatics, cheminformatics, machine learning, and mathematics are discussed. This review will be beneficial to researchers who are looking for ways to contribute to SARS-CoV-2 studies and those who are interested in the status of the field.

Abstract
In this work, the discovery and description of PF-07321332, a major bioavailable oral SARS-CoV-2 protease inhibitor with in vitro human coronavirus antiviral activity, and excellent selection of off-target and in vivo immune profiles are reported. Various drugs and novel compound candidates for the treatment of the COVID-19 pandemic have been developed. PF-07321332 (or nirmatrelvir) is a new oral antiviral drug developed by Pfizer. In response to the pandemic, Pfizer has developed the COVID vaccine and in 2022 will launch its new major anti-SARS-Cov-2 protease inhibitor (PI). The combination of ritonavir and nirmatrelvir is under study in phase III of the clinical trial with a brand name Paxlovid. Paxlovid is an active 3Cl protease inhibitor. Paxlovid exerts its antiviral efficacy by inhibiting a necessary protease in the viral replication procedure. Proteases of coronavirus cleave several sites in the viral polyprotein where pyrrolidone was replaced by flexible glutamine. Due to the coronavirus pandemic, there is high demand for synthesis and development of this novel drug. Herein, we report the synthetic route and the mechanism of action was recently published on nirmatrelvir. Also, a comparison of the performance of two new oral antiviruses (molnupiravir and nirmatrelvir) for the treatment of COVID-19 is described. This review will be helpful for different disciplines such as biochemistry, organic chemistry, medicinal chemistry, and pharmacology.

[PMID: 35600633 PMCID: PMC9114151 DOI: 10.1016/j.jaim.2022.100587] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 04/06/2022] [Accepted: 05/06/2022] [Indexed: 01/22/2023] Open
Abstract
Background Ayurveda herbal formulation AYUSH-64, proven to treat malaria and influenza-like illness in india was repurposed for COVID-19 patients considering preliminary evidances, however, scientific data was not available. Aim To evaluate the preliminary efficacy and safety of AYUSH 64 as an add-on to standard of care in mild COVID19 patients. Materials and methods A single centre, randomized, open-labeled, controlled, pilot study were conducted on mild COVID 19 confirmed patients. Patients allotted in interventional group (n = 41) recieved AYUSH 64, 3 gm per day in three divided dose for 14 days as an adjuvant to standard of care (SOC) whereas control group received SOC (n = 39) alone. Outcomes were reduction in WHO ordinal scale for clinical improvement, all-cause mortality, incidence of COVID19 symptoms among asymptomatic patients at baseline, use for oxygen therapy, use for a mechanical ventilator, the total duration of symptomatic phase and adverse events. Results Mean score of WHO ordinal scale was reduced as time lapse in both the groups (f (1) = 20.5, p < 0.001) indicating clinical improvement among groups. There was no statistically significant difference in mean WHO ordinal scale between groups (f (1) = 0.98, p = 0.32). The proportion of asymptomatic patients progressing to the symptomatic stage is lower in AYUSH 64 group [OR, 0.68 (CI, 0.17–2.66)]. Mean days for the total duration of the symptomatic phase was also short in AYUSH 64 group (4.68 ± 3.29 days) compared to SOC group (5.81 ± 3.5 days). No incidence of the requirement of a mechanical ventilator, adverse drug reaction and death were observed in either of the groups. Conclusion The findings of this pilot study show that an integrated approach of AYUSH 64 with SOC provide early trends of benefit by reduction in disease progression and in total symptom duration. However, its effects remains inconclusive on outcomes such as all cause mortality, use of oxygen therapy, invasive ventilator due to sparse outcomes.

Combination Therapy of Ledipasvir and Itraconazole in the Treatment of COVID-19 Patients Coinfected with Black Fungus: An In Silico Statement. BIOMED RESEARCH INTERNATIONAL 2022; 2022:5904261.

Abstract
The manuscript mainly aimed at providing clues on improving the innate immunity of coronavirus patients and safeguarding them from both new mutant strains and black fungus infections. Coronavirus is readily mutating from one variant to another. Among the several variants, we selected SARS-CoV-2 B.1.1.7 in this study. Upon infection of any virus, ideally, the phagocytic cells of the host engulf and destroy the virus by a mechanism called phagocytosis. However, compromised immunity impairs phagocytosis, and thus, restoring the immune system is crucial for a speedy recovery of infected patients. The autophagy and activation of Toll-like receptor-4 are the only ways to restore innate immunity. Recently, immunocompromised COVID-19 patients have been suffering from the coinfection of black fungus. Rhizomucor, a black fungus species, causes more than 75% of cases of mucormycosis. Here, we present the results of molecular docking studies of sixty approved antiviral drugs targeting receptors associated with the SARS-CoV-2 B 1.1.7 variant (PDB id: 7NEH), activating the innate immune system (PDB id: 5YEC and 5IJC). We also studied the twenty approved antifungal drugs with Rhizomucor miehei lipase propeptide (PDB id: 6QPR) to identify the possible combination therapy for patients coinfected with coronavirus and black fungus. The ledipasvir showed excellent docking interactions with the 7NEH, 5YEC, and 5IJC, indicating that it is a perfect candidate for the treatment of COVID-19 patients. Itraconazole showed significant interaction with 6QPR of Rhizomucor miehei, suggesting that itraconazole can treat black fungus infections. In conclusion, the combination therapy of ledipasvir and itraconazole can be a better alternative for treating COVID-19 patients coinfected with black fungus.

Abstract
Originating in ancient India, Ayurveda is an alternative medicinal approach that provides substantial evidence for a theoretical-level analysis of all aspects of life. Unlike modern medicine, Ayurveda is based upon tridoshas (Vata, pitta, and Kapha) and Prakriti. On the other hand, the research of all the genes involved at the proteomics, metabolomics, and transcriptome levels are referred to as genomics. Geoclimatic regions (deshanupatini), familial characteristics (kulanupatini), and ethnicity (jatiprasakta) have all been shown to affect phenotypic variability. The combination of genomics with Ayurveda known as ayurgenomics provided new insights into tridosha that may pave the way for precision medicine (personalized medicine). Through successful coordination of “omics,” Prakriti-based treatments can help change the existing situation in health care. Prakriti refers to an individual’s behavioral trait, which is established at the moment of birth and cannot be fully altered during one’s existence. Ayurvedic methodologies are based on three Prakriti aspects: aushadhi (medication), vihara (lifestyle), and ahara (diet). A foundation of Prakriti-based medicine, preventative medicine, and improvement of life quality with longevity can be accomplished through these ayurvedic characteristics. In this perspective, we try to understand prakriti’s use in personalized medicine, and how to integrate it with programs for drug development and discovery.

[PMID: 35186674 PMCID: PMC8832856 DOI: 10.1016/j.btre.2022.e00712] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Accepted: 02/10/2022] [Indexed: 12/12/2022]
Abstract
Optimized therapeutic bio-compounds supported by bio-acceptable nanosystems (i.e., precise nanomedicine) have ability to promote health via maintaining body structure, organ function, and controlling chronic and acute effects. Therefore, nano-nutraceuticals (designed to neutralize virus, inhibit virus bindings with receptors, and support immunity) utilization can manage COVID-19 pre/post-infection effects. To explore these approaches well, our mini-review explores optimized bio-active compounds, their ability to influence SARS-CoV-2 infection, improvement in performance supported by precise nanomedicine approach, and challenges along with prospects. Such optimized pharmacologically relevant therapeutic cargo not only affect SARS-CoV-2 but will support other organs which show functional alternation due to SARS-CoV-2 for example, neurological functions. Hence, coupling the nutraceuticals with the nano-pharmacology perspective of higher efficacy via targeted delivery action can pave a novel way for health experts to plan future research needed to manage post COVID-19 infection effect where a longer efficacy with no side-effects is a key requirement.

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.

Abstract
Owing to the instability of Epigallocatechin Gallate (EGCG), it may undergo auto-oxidation and form oxidised products or dimers. In the present study, we aimed to evaluate the therapeutic effects, including antioxidation and immunomodulatory action, of the Oxidised Epigallocatechin Gallate (O-EGCG) as compared to native EGCG and the action of these compounds on main protease (Mpro) docking against SARS-CoV-2. HCT-116 (Human Colon Cancer) cell lines were used to estimate the total antioxidant capacity and lipid peroxidation levels and pro-inflammatory markers (human IL-6, IL-1β, TNF-α). Further, molecular docking analysis was performed by AutoDock and visualised in Discovery studio. Improved antioxidant capacity of O-EGCG was observed, and there was a significant decrease in the inflammatory markers (IL-1β, IL-6, and TNF-α) when O-EGCG was applied as compared to EGCG. The O-EGCG was shown to be strongly associated with the highest docking score and active site residues of IL-1, IL-6, and TNF- α, as well as the Mpro of SARS-CoV-2, according to in silico approach. The in vitro and in silico analyses indicate an improved therapeutic action of the oxidised form of EGCG. The effective inhibitory action of O-EGCG against SARS-CoV-2 suggests further exploration of the compound against COVID-19 and its efficacy. However, in vivo studies and understanding of the mechanism of action of O-EGCG may yield a better opinion on the use of O-EGCG and future human clinical trials.

Abstract
Corona Virus disease (COVID-19) has become a global pandemic resulting in large scale morbidity and mortality worldwide. The causative agent SARS-CoV-2 is easily subject to repeated mutation with swift spread of infection. The management of COVID-19 has been a big challenge on account of non-availability of specific therapeutic agents. The complex and multifactorial pathophysiology of COVID-19 requires therapeutic agents with anti-viral properties against SARS-CoV-2 as well as immunomodulatory properties that have a broad-spectrum effectiveness covering the disease in totality. AYUSH-64, a poly-herbal formulation developed by CCRAS, Ministry of AYUSH, Govt. of India through extensive pharmacological, toxicological and clinical studies has proven efficacy in infective febrile conditions such as malaria, micro filaremia, chikungunya and influenza with no safety issues observed in published clinical studies. Based on the empirical evidence, it has been repurposed as an adjuvant to standard care or standalone therapy for asymptomatic and mild to moderate cases of COVID- 19 by the Ministry of AYUSH at a time when India is experiencing wave after wave of COVID-19 variants causing mass distress to the healthcare delivery systems. AYUSH- 64 has four ingredients having immune-modulator, anti-inflammatory, antipyretic, antioxidant and anti-viral activities. These effects could arrest the extreme inflammatory responses in COVID-19 that causes progression to significant morbidity. Several clinical studies on AYUSH-64 in asymptomatic and mild to moderate cases of COVID-19 have been undertaken at reputed medical institutions across the country. The evidence generated through these studies is promising. AYUSH-64 has also been incorporated in the National COVID management protocol based on Ayurveda and Yoga by Government of India for asymptomatic and mild cases of COVID-19. Further, on the basis of tangible evidence generated through robust clinical and experimental studies on AYUSH-64, the Ministry of AYUSH has launched nation-wide campaign for mass distribution of AYUSH-64 to asymptomatic, mild to moderate COVID-19 patients in home isolation to reduce the burden on the hospital-based health care delivery system. This review will highlight about the specifications of AYUSH-64, its probable mechanism of action, its repurposing for COVID-19, various clinical and experimental studies undertaken during the COVID-19 pandemic and the initiatives taken to translate the outcomes of these studies on AYUSH-64.

Protective effects of a small molecule inhibitor ligand against hyperphosphorylated tau-induced mitochondrial and synaptic toxicities in Alzheimer disease. Hum Mol Genet 2021; 31:244-261. [PMID: 34432046 DOI: 10.1093/hmg/ddab244] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Revised: 08/12/2021] [Accepted: 08/17/2021] [Indexed: 12/14/2022] Open
Abstract
The purpose of our study is to understand the protective effects of small molecule ligands for phosphorylated tau (p-tau) in Alzheimer's disease (ad) progression. Many reports show evidence that p-tau is reported to be an important contributor to the formation of paired helical filaments (PHFs) and neurofibrillary tangles (NFTs) in ad neurons. In ad, glycogen synthase kinase-3 beta (GSK3β), cyclin-dependent kinase- 5 (CDK5) and dual specificity tyrosine-phosphorylation-regulated kinase 1A (DYRK1A), are the three important kinases responsible for tau hyperphosphorylation. Currently, there are no drugs and/or small molecules that reduce the toxicity of p-tau in ad. In the present study, we rationally selected and validated small molecule ligands that binds to the phosphorylated tau at SER23 (Ser 285). We also assessed the molecular dynamics and validated molecular docking sites for the three best ligands. Based on the best docking scores -8.09, -7.9 and - 7.8 kcal/mol, we found that ligand 1 binds to key hyperphosphorylation residues of p-tau that inhibit abnormal PHF-tau, DYRK1A, and GKS3β that reduce p-tau levels in ad. Using biochemical, molecular, immunoblotting, immunofluorescence, and transmission electron microscopy analyses, we studied the ligand 1 inhibition as well as mitochondrial and synaptic protective effects in immortalized primary hippocampal neuronal (HT22) cells. We found interactions between NAT10-262501 (ligand 1) and p-tau at key phosphorylation sites and these ligand-based inhibitions decreased PHF-tau, DYRK1A and GSK3β levels. We also found increased mitochondrial biogenesis, mitochondrial fusion and synaptic activities and reduced mitochondrial fission in ligand 1-treated mutant tau HT22 cells. Based on these results, we cautiously conclude that p-tau NAT10-262501 (ligand 1) reduces hyperphosphorylation of tau based GKS3β and CDK5 kinase regulation in ad, and aids in the maintenance of neuronal structure, mitochondrial dynamics, and biogenesis with a possible therapeutic drug target for ad.

Abstract
The novel coronavirus disease, caused by severe acute respiratory coronavirus 2 (SARS-CoV-2), rapidly spreading around the world, poses a major threat to the global public health. Herein, we demonstrated the binding mechanism of PF-07321332, α-ketoamide, lopinavir, and ritonavir to the coronavirus 3-chymotrypsin-like-protease (3CLpro) by means of docking and molecular dynamic (MD) simulations. The analysis of MD trajectories of 3CLpro with PF-07321332, α-ketoamide, lopinavir, and ritonavir revealed that 3CLpro-PF-07321332 and 3CLpro-α-ketoamide complexes remained stable compared with 3CLpro-ritonavir and 3CLpro-lopinavir. Investigating the dynamic behavior of ligand-protein interaction, ligands PF-07321332 and α-ketoamide showed stronger bonding via making interactions with catalytic dyad residues His41-Cys145 of 3CLpro. Lopinavir and ritonavir were unable to disrupt the catalytic dyad, as illustrated by increased bond length during the MD simulation. To decipher the ligand binding mode and affinity, ligand interactions with SARS-CoV-2 proteases and binding energy were calculated. The binding energy of the bespoke antiviral PF-07321332 clinical candidate was two times higher than that of α-ketoamide and three times than that of lopinavir and ritonavir. Our study elucidated in detail the binding mechanism of the potent PF-07321332 to 3CLpro along with the low potency of lopinavir and ritonavir due to weak binding affinity demonstrated by the binding energy data. This study will be helpful for the development and optimization of more specific compounds to combat coronavirus disease.

Abstract
Background The evidence on the efficacy and safety of Ayurveda interventions as an add-on to the standard conventional care for coronavirus disease-2019 (COVID-19) is limited. Aim and objective This study was planned to explore the potential of AYUSH-64 as an add-on to conventional care in improving the clinical recovery and negative reverse transcription-polymerase chain reaction (RT-PCR) conversion in asymptomatic and mild COVID-19 cases. Materials and methods An open-label randomized controlled study was conducted at Government Medical College, Nagpur, Maharashtra, India, with a sample size of 60 participants. In this study, asymptomatic or mild COVID-19 patients were randomized and allocated into intervention and control groups (CG) in a 1:1 ratio. AYUSH-64 two capsules (500 mg each) were administered thrice daily, after food with water for 30 days along with standard care in the intervention group (IG), while the CG received only standard care. The primary outcome was the proportion of participants who turned RT-PCR negative for COVID-19 at 7th, 15th, 22nd and 30th days. Secondary outcomes were the proportion of participants who attained clinical recovery at 7th, 15th, 22nd and 30th days, change in laboratory parameters on the 30th day and incidence of adverse drug reactions/adverse events. The data were compared within group using paired sample t-test/Wilcoxon signed-rank test and between group using independent sample t-test/Mann-Whitney test. Results Statistically significant difference was not observed in the proportion of participants who turned RT-PCR negative during each of the follow-ups (P = 0.134) and both groups demonstrated comparable efficacy. The clinical recovery in terms of complete relief in symptoms in the symptomatic participants was 60% and 37% on day 15 (P = 0.098) and 100% and 85.2% on day 30 (P = 0.112) in the intervention and CG, respectively. The improvement in the inflammatory markers such as interleukin (IL)-6, tumor necrosis factor-α (TNF-α), and D-dimer was statistically significant (P < 0.05) in the IG, whereas in the CG, it was statistically significant for D-dimer only. None of the participants developed any complications nor were any significant ADR/AE observed in the groups. Conclusions In patients with asymptomatic and mild COVID-19, AYUSH-64, as add-on to standard conventional care, contributed to improved clinical recovery and demonstrated potential in reducing the levels of pro-inflammatory markers such as IL-6 and TNF-α. Further, both the groups demonstrated comparable efficacy regarding negative RT-PCR for COVID-19.
