Evaluation of Analgesic and Anti-Inflammatory Activity of Mahanimba (Melia Azedarach Linn.) Moola Ghanavati In Albino Rats

The drugs which are used as analgesic and anti inflammatory agents cause many side effects and toxic effects. Many medicines of plant origin have been used from many years without any side effects. In Ayurvedic ancient text named Gada Nigraha, it has been mentioned that Mahanimba (Melia azedarach Linn.) Moola can be used in the management of Gridhrasi (Sciatica). In Gridhrasi pain and inflammation of Sciatic nerve is the main cardinal symptoms. So, in this pharmacological study evaluation of analgesic and anti inflammatory activity of test drug Mahanimba Moola have been assessed with compare to Standard drug Parijata Patra (Nyctanthes arbortristis)

A comprehensive review on Vrishan Karma (aphrodisiac action) by Piyush (cow colostrum)

Piyush (Cow colostrum) is the first milk which cow gives after giving birth to calf. As per our Ayurvedic texts this Piyush is having Madhura Rasa and Guru-Snigdha Gunas. Due to its properties it is VataPitta Dosha Nashak and Kapha Dosha Vardhak. Thus, these all factors affects in the nourishment of all the seven Dhatus (tissues) of human body. Nourishment of seven Dhatus lead to Vrishan Karma (aphrodisiac action) of body. Vrishan Karma of human body is directly related with the Vyadhiksamatava (Immunity). If Vyadhikshamatva of body is more then the Vrishyata of body increases. As per Modern Science Piyush is known as a cow colostrum. It contains more Immunoglobulin, lactose, protein, fat than normal cow milk. Ultimately these all factors help in increasing the level of Immunity which is acquired immunity. Thus Piyush provide a novel treatment option for the Vrishan Karma in body. This review explores the current knowledge on the beneficial effect of Piyush supplementation in the above conditio

Cp2ZrCl2: AN EFFICIENT CATALYST FOR MULTICOMPONENT SYNTHESIS OF CAROTENOID DEHYDROSQUALENE SYNTHASE INHIBITING PYRANO[2,3-d]PYRIMIDINEDIONES

Objectives: The present protocol deals with zirconocene dichloride (Cp2ZrCl2) catalyzed synthesis of pyrano[2,3-d]pyrimidinediones through one-pot multicomponent reactions of aromatic aldehydes with malononitrile and barbituric acid at ambient temperature. All the synthesized compounds were characterized and evaluated for antibacterial, antifungal, and antioxidant activities. Furthermore, a molecular docking was carried out to reveal the atomic insights between synthesized compounds and carotenoid dehydrosqualene synthase (PDB ID: 3ACX). Methods: All the synthesized compounds were evaluated for their in vitro antimicrobial activity by diffusion method. Antioxidant activities such as 1,1-diphenyl-2-picrylhydrazyl and radical scavenging activity. A mixture of barbituric acid 1 (1 mmol), malononitrile 2 (1 mmol), benzaldehyde 3a (1 mmol), ethanol (5 mL), and Cp2ZrCl2 (5 mol %) was stirred at ambient temperature for specified time. After completion of reaction as indicated by thin-layer chromatography, the obtained crude product was filtered and purified by column chromatography on silica gel (Merck, 60–120 mesh) using ethyl acetate:pet. ether to afford pure product which was then characterized by spectroscopic methods such by FTIR, nuclear magnetic resonance (1H NMR), 13C NMR, and mass spectroscopy. Results: All the synthesized pyrano[2,3-d]pyrimidinediones were characterized by spectroscopic analysis. The results revealed that pyrano[2,3-d] pyrimidinediones (4 a-k) displayed the zone of inhibition in the range of 3–13 mm. The most active compound 4b displayed largest zone of inhibition of 13 mm for Escherichia coli (NCIM-2832) and 9 mm for Bacillus subtilis (NCIM-2635). The antifungal and antioxidant activity of all synthesized pyrano[2,3-d]pyrimidinediones (4a-k) showed moderate to good activity. Molecular docking studies suggest that pyrano[2,3-d]pyrimidinediones might inhibit the carotenoid dehydrosqualene synthase activity. Conclusion: All the synthesized pyrano[2,3-d]pyrimidinediones display moderate to good antibacterial, antifungal, and antioxidant activity. This molecular docking studies supported that pyrano[2,3-d]pyrimidinediones might inhibit the carotenoid dehydrosqualene synthase (PDB ID: 3ACX)

Environmental pollutants and their impact on COVID‐19 spread: Current problem and future resolutions

Abstract COVID‐19 is the greatest crucial universal health issue of the century and the extreme challenge that came after the 2nd World War faced by humankind. In 2019, different strains of the coronavirus have emerged drastically, that as severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) which is the causative agent of corona disease. As far as human civilization history, there have been occurrences of severe diseases and outbreaks of various viruses. According to World Health Organization reports, throughout the world, the present outbreak of COVID‐19 has engulfed more than 200 countries affecting 241,471,559 individuals and more than 4,914,092 people lost their lives. SARS‐CoV‐2 outbreak is severely disturbing the worldwide economy at present. The urgent need of recent times is to understand the environmental aspect of COVID‐19 disease. Hence to fulfill this point, the present review article is compiled with a brief discussion about all the minute points of the COVID‐19 pandemic related to the environment: origin and present scenario, the occurrence of SARS‐CoV‐2 in environmental habitats, the effect of COVID‐19 on human health, and environment, environmental factors influencing the transmission and spreading of SARS‐CoV‐2. This review explains micro and macro pollutants in hospital and urban wastewater influencing COVID‐19, detection of SARS‐CoV‐2, current global drug strategies to control replication and spread of SARS‐CoV‐2 from the environment, future approaches, and guidelines to prevent and control upcoming pandemics. The SARS‐CoV‐2 structural details and their effect on humans have been already well presented but the research about environmental factors affecting COVID‐19 could be important points to fight present and future pandemics

Molecular Modeling Insights into Metal-Organic Frameworks (MOFs) as a Potential Matrix for Immobilization of Lipase: An In Silico Study

CRL is a highly versatile enzyme that finds extensive utility in numerous industries, which is attributed to its selectivity and catalytic efficiency, which have been impeded by the impracticality of its implementation, leading to a loss of native catalytic activity and non-reusability. Enzyme immobilization is a necessary step for enabling its reuse, and it provides methods for regulating the biocatalyst’s functional efficacy in a synthetic setting. MOFs represent a novel category of porous materials possessing distinct superlative features that make MOFs an optimal host matrix for developing enzyme-MOF composites. In this study, we employed molecular modeling approaches, for instance, molecular docking and MD simulation, to explore the interactions between CRL and a specific MOF, ZIF-8. The present study involved conducting secondary structural analysis and homology modeling of CRL, followed by docking ZIF-8 with CRL. The results of the molecular docking analysis indicate that ZIF-8 was situated within the active site pocket of CRL, where it formed hydrogen bonds with Val-81, Phe-87, Ser-91, Asp-231, Thr-132, Lue-297, Phe-296, Phe-344, Thr-347, and Ser-450. The MD simulation analysis revealed that the CRL and ZIF-8 docked complex exhibited stability over the entire simulation period, and all interactions presented in the initial docked complex were maintained throughout the simulation. The findings derived from this investigation could promote comprehension of the molecular mechanisms underlying the interaction between CRL and ZIF-8 as well as the development of immobilized CRL for diverse industrial purposes
