Cannabis effectiveness on immunologic potency of pulmonary contagion.

Respiratory illnesses and its repercussions are becoming more prevalent worldwide. It is necessary to research both innovative treatment and preventative techniques. Millions of confirmed cases and fatalities from the COVID-19 epidemic occurred over the previous two years. According to the review research, cannabinoids are a class of medicines that should be considered for the treatment of respiratory conditions. Cannabinoids and inhibitors of endocannabinoid degradation have illustrated advantageous anti-inflammatory, asthma, pulmonary fibrosis, and pulmonary artery hypotension in numerous studies (in vitro and in vivo). It has been also noted that CB2 receptors on macrophages and T-helper cells may be particularly triggered to lower inflammation in COVID-19 patients. Since the majority of lung tissue contains cannabinoid receptors, cannabis can be an effective medical tool for treating COVID-19 as well as pulmonary infections. Notably, CB2 and CB1 receptors play a major role in immune system modulation and anti-inflammatory activities. In this review, we put forth the idea that cannabis might be helpful in treating pulmonary contagion brought on by viral integration, such as that caused by SARS-CoV-2, haemophilus influenza type b, Streptococcus pneumoniae, influenza virus, and respiratory syncytial virus. Also, a detailed overview of CB receptors, intricate mechanisms, is highlighted connecting link with COVID-19 viral structural modifications along with molecular basis of CB receptors in diminishing viral load in pulmonary disorders supported through evident literature studies. Further, futuristic evaluations on cannabis potency through novel formulation development focusing on in vivo/in vitro systems can produce promising results.

Anti-cancer potential of substituted "amino-alkyl-rhodamine" derivatives against MCF-7 human breast cancer cell line.

Breast cancer is the most prevalent diagnosed cancer among women and the main cause of morbidity and mortality. As for breast cancer, MCF-7 cells are an important candidate since they are widely utilized in research for estrogen receptor (ER)-positive breast cancer cell assays, and various sub-clones have been identified to reflect different classes of ER-positive tumors with varied levels of nuclear receptor expression. Rhodamines and its derivatives have shown a great interest over the past two decades due to their excellent structural and spectroscopic properties. Rhodamine derivatives have been widely investigated for their mitochondrial targeting and chemotherapeutic properties. Rhodamine derivatives, in particular, have been widely investigated for their therapeutic properties. In this regard, several studies have shown that rhodamine dye derivatives have promising in vitro and in vivo therapeutic efficacy. The present study deals with potential anticancer activity of few synthesized rhodamine derivatives against MCF-7 cell lines.

Evaluation of Antioxidant, Antimicrobial, and Antiurolithiatic Potential of Different Solvent Extracts of Aerva lanata Linn Flowers.

INTRODUCTION: Aerva lanata (Linn) of family Amaranthaceae is an important and commonly used plant for its medicinal and pharmacological properties and proving the traditional uses of flowers of A. lanata Linn. OBJECTIVE: All extracts of A. lanata were further evaluated for antioxidant, antimicrobial, and antiurolithiatic potential to scientifically prove the traditional uses. MATERIALS AND METHODS: In the present investigation, different solvent extracts of flowers were obtained using a Soxhlet extractor. Microorganisms were obtained from IMTECH, Chandigarh. Antiurolithiatic study was carried out in Albino Research and Training Centre, Hyderabad. RESULTS: Regardless of the antioxidant studied, the methanolic extract presented the highest antioxidant activity and the aqueous extracts offered the lowest, following the order: methanolic extract > ethyl acetate > chloroform > aqueous. The results of this antimicrobial study indicate that methanolic extract of A. lanata could be used as antimicrobial agents. Overall, the methanolic flower extract of A. lanata (Linn) was significantly more promising as antiurolithiatic spectrum. This result also suggested the potential usefulness of the methanolic extract as an antiurolithiatic agent. CONCLUSION: Henceforward, this research can be acknowledged as a prime new report that focuses on the application of A. lanata (Linn) as an antioxidant, antimicrobial, and antiurolithiatic agent. SUMMARY: Overall, methanolic flower extract of Aerva lanata Linn showed promising antioxidant activityAdditionally, methanolic flower extract of A. lanata Linn exhibited remarkable antimicrobial and antiurolithiatic potential.

Computational tool for immunotoxic assessment of pyrethroids toward adaptive immune cell receptors.

BACKGROUND: Pyrethroids have prominently known for their insecticidal actions worldwide, but recent reports as anticancer and antiviral applications gained a lot of interest to further understand their safety and immunotoxicity. OBJECTIVE: This encouraged us to carry out our present study to evaluate the interactions of pyrethroids toward adaptive immune cell receptors. MATERIALS AND METHODS: Type 1 and Type 2 pyrethroids were tested on T (CD4 and CD8) and B (CD28 and CD45) immune cell receptors using Maestro 9.3 (Schrödinger, LLC, Cambridge, USA). In addition, top-ranked tested ligands were too explored for toxicity prediction in rodents using ProTOX tool. RESULTS: Pyrethroids (specifically type 2) such as fenvalerate (-5.534 kcal/mol: CD8), fluvalinate (-4.644 and - 4.431 kcal/mol: CD4 and CD45), and cypermethrin (-3.535 kcal/mol: CD28) have outcome in less energy or more affinity for B-cell and T-cell immune receptors which may later result in the immunosuppressive and hypersensitivity reactions. CONCLUSION: The current findings have uncovered that there is a further need to assess the Type 2 pyrethroids with wet laboratory experiments to understand the chemical nature of pyrethroid-induced immunotoxicity. SUMMARY: Fenvalerate showed apex glide score toward CD8 immune receptor, while fluvalinate confirmed top-ranked binding with CD4 and CD45 immune proteinsIn addition, cypermethrin outcame in top glide score against CD28 immune receptorTop dock hits (Type 2) pyrethroids have shown probable toxicity targets toward AOFA: Amine oxidase (flavin-containing) A and PGH1: Prostaglandin G/H synthase 1, respectively. Abbreviations used: PDB: Protein Data Bank; AOFA: Amine oxidase (flavin-containing) A; PGH 1: Prostaglandin G/H synthase 1.
