Oxyria digyna: A review on the nutritional value, phytochemistry and ethnopharmacology

2022-11-26T13:50:07+00:00

Oxyria digyna is an important herb, having a wide geographical distribution. Nutritionally, it has found its place in the meals of various populations living in different parts of the world, both in raw and cooked forms. Traditional uses identified its indications in cancer, depression, hepatitis, jaundice, colic, gastritis, appetite, diuretic, constipation, cough, chest congestion, boils, scurvy. Several pharmacological activities have hastened further experimental exploration of this plant, establishing its efficacy for diabetes, free radical scavenging, gout, and cancer. The important bioactive compounds isolated from this plant are vitexin, orientin, hesperidin, quercetin and stigmasterol. These compounds have extensive effects on human physiology and provide proof that O. digyna is potentially unexplored for its pharmacological efficacy. A detailed metabolomic approach is required to fully characterize the plant as a potential nutraceutical candidate with multiple therapeutic potentials.

Curcumin targeting oxidative mediators for therapeutic effects in diabetes and its related complications

2022-11-26T14:01:27+00:00

DIABETES mellitus is a multifactorial chronic metabolic disorder characterized by altered metabolism of macro – nutrients such fats, proteins and carbohydrates associated with disturbances in insulin activity. Diabetes mellitus complications include, diabetic retinopathy, diabetic cardiomyopathy, diabetic encephalopathy, diabetic periodontitis and diabetic nephropathy. These complications are mostly induced by inflammatory and oxidative mediators. Curcumin is a polyphenol extracted from turmeric and it is well known for its antioxidant, anti-inflammatory and antiapoptotic activities. It effectively targets oxidative mediators in diabetes mellitus through regulation of several signaling pathways. Insulin resistance is commonly caused due to impairment in the signaling pathways related to insulin and the target tissues pose lesser or no response to circulating insulin. Curcumin is a potent therapeutic agent that targets oxidative stress mediators in diabetes mellitus and its resistant version leading to favorable therapeutic outcomes in diabetes complications. This review has thrown sufficient light on the therapeutic potential of curcumin targeting oxidative mediators in diabetes and its related complications.

Role of Quercetin in DNA Repair and Dysregulated Metabolism. Possible Target to Combat Drug Resistance in Cancer

2022-11-26T15:16:19+00:00

ONE of the biggest challenges in medicine is finding a remedy for cancer. Earlier to 1950, surgery was thought to be the main form of treatment for cancer. Later, radiation therapy was added as a second method to treat localized tumours. Cancer drug development have modified into billion-dollar industry supported by the advent of novel targeted therapies; however, the basic principles and limitation of chemotherapy are still the same. For instance, chemotherapy is associated with increase psychological distress, fatigue, anxiety accompanied by intense financial distress ultimately causing decrease quality of life. Dietary nutrients, calories limitation and fasting are known to have a large impact in modifying many types of diseases including cancer, and obesity. Quercetin a plant derived flavonoid found abundantly in fruits, vegetables and many beverages possess multiple pharmacological activities shows encouraging potential in treatment and prevention of various types of cancers. Quercetin aglycone has also been shown to modulate several signal transduction pathways involving MEK/ERK and Nrf2/keap1, which are associated with the processes of inflammation and carcinogenesis. Quercetin is an attractive natural compound for cancer prevention due to its beneficial anti-mutagenic and anti-proliferative effects, its strong antioxidative capacity, and its role in the regulation of cell signaling, cell cycle and apoptosis, all demonstrated in animal and in vitro studies. The aim of the present review is to summarize the key aspects of quercetin role, mechanisms, and future prospects in treating and prevention of cancer by modulating DNA repair, metabolism and drug resistance.

Anxiolytic and antidepressant potential of extracts of Duchesnea Indica in animal models

2022-11-26T15:27:10+00:00

THIS study was designed to investigate the anxiolytic and antidepressant activity of Duchesnea Indica. The methanolic extract and n-hexane fraction of plant were tested in albino mice (20-30 g of 6-8 week). Safety profile of each extract was determined at different doses. Anxiolytic effect of plant was determined by Elevated Plus Maze and Light and Dark Model at different doses of methanolic and n-hexane extract. Antidepressant activities were assisted by Tail Suspension and Forced Swim Model at different doses. Result illustrated that D. Indica had a significant (P < 0.05) potential of reducing anxiety and depression. The methanolic extract at 100 mg and 200 mg significantly increased the time spend in light region of light and dark model and more time spent in open arm of Elevated Plus Maze model. n-hexane extract at dose of 5 mg and 10 mg/kg significantly increases the time spend in light region of Light and dark model and more time spend in open arm of Elevated Plus Maze model as compare to Control group. Methanolic extract of D. Indica significantly reduced the time of immobility in Tail Suspension and Force Swim Model at Dose of 100 mg and 200mg/kg. n-hexane extract also exhibit anti-depressant effect by reducing the time of immobility in Force swim and tail suspension Model at 100 mg and 200mg/kg dose as compare to control group. From the above observations, it could be assumed that the plant has marked anxiolytic and antidepressant potential. However further additional studies will be necessary to determine the underlying exact mechanism and clinical uses.

Anticancer Potential of Diospyros kaki (persimmon) polyphenols against AKT1 (6CCY): docking based in silico study

2022-11-26T15:40:56+00:00

The elevation of AKT activity in many aggressive tumors, and AKT signaling is frequently compromised in various cancers. The range of AKT inhibitors' therapeutic effects extends beyond cancer management. AKT inhibitors may potentially be used to treat cancer. The study aims to find a potent drug compound from D. kaki polyphenols that could serve as an AKT1 inhibitor. In silico study using Molecular operating environment (MOE) software was employed to find the therapeutic potential of phytochemicals from D. kaki against AKT1 via molecular docking and drug-like properties. Results of the study revealed that acarbose (compound 1) has the highest docking score of -7.4615 with receptor protein 6CCY, followed by quercetin 3-O-glucoside (compound 2) with a docking score of -6.86404133 measured in terms of kcal/mol. Pocket residues involved in protein-ligand interaction was GLU234, GLU278, ASP292, ASN79, LYS276, LYS189, PHE161, HIS194, LYS179, ASP291, LYS158, GLU278. Thus, bioactive compounds from D. kaki may be a potentially novel anticancer agent by inhibiting AKT1.
