JOURNAL OF ETHNOPHARMACOLOGY 2023; 310:116352. [PMID: 36933876 DOI: 10.1016/j.jep.2023.116352] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 02/14/2023] [Accepted: 03/01/2023] [Indexed: 06/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Terminalia arjuna (Roxb. ex DC.) Wight & Arnot (Combretaceae) is one of the most frequently used medicinal trees in Indian traditional medicinal systems. It is used for the treatment of a variety of diseases including cardiovascular disorders. AIM OF THE STUDY The purpose of this review was to provide a comprehensive overview of the phytochemistry, medicinal uses, toxicity, and industrial applications of T. arjuna bark (BTA), as well as to identify gaps in research and applications of this important tree. It also aimed to analyze trends and future research paths to utilize the full potential of this tree. MATERIALS AND METHODS Extensive bibliographic research on the T. arjuna tree was carried out using scientific research engines and databases such as Google Scholar, PubMed, and Web of Science, covering all relevant English-language articles. The database "World Flora Online (WFO)" (http://www.worldfloraonline.org) was used to confirm plant taxonomy. RESULTS To date, BTA has been traditionally employed for several disorders such as snakebites, scorpion stings, gleets, earaches, dysentery, sexual disorders, and urinary tract infections along with the cardioprotective activity. About 38 phytocompounds were identified from BTA and were classified as triterpenoids, tannins, flavonoids, and glycosides. A wide range of in vitro and in vivo pharmacological effects of BTA were reported such as anti-cancer, antimicrobial, antiviral, anti-inflammatory, antioxidant, hepatoprotective, anti-allergic, anti-diabetic, and wound healing activities. The oral administration of BTA (500 mg/kg) per day did not result in any toxicity in humans. The in vivo acute and sub-acute toxicity analysis of the methanol extract of BTA and one of its major compounds, 7-methyl gallate, did not produce any adverse effects up to a dose of 1000 mg/kg. CONCLUSIONS This comprehensive review highlights various aspects of traditional knowledge, phytochemicals, and pharmacological significance of BTA. The review covered safety information on employing BTA in pharmaceutical dosage forms. Despite its long history of medicinal benefit, more studies are needed to understand the molecular mechanisms, structure-activity relationship, and potential synergistic and antagonistic effects of its phytocompounds, drug administration, drug-drug interactions, and toxicological effects.

Characteristics of Food Protein-Derived Antidiabetic Bioactive Peptides: A Literature Update. Int J Mol Sci 2021; 22:ijms22179508.

Abstract
Diabetes, a glucose metabolic disorder, is considered one of the biggest challenges associated with a complex complication of health crises in the modern lifestyle. Inhibition or reduction of the dipeptidyl peptidase IV (DPP-IV), alpha-glucosidase, and protein-tyrosine phosphatase 1B (PTP-1B) enzyme activities or expressions are notably considered as the promising therapeutic strategies for the management of type 2 diabetes (T2D). Various food protein-derived antidiabetic bioactive peptides have been isolated and verified. This review provides an overview of the DPP-IV, PTP-1B, and α-glucosidase inhibitors, and updates on the methods for the discovery of DPP-IV inhibitory peptides released from food-protein hydrolysate. The finding of novel bioactive peptides involves studies about the strategy of separation fractionation, the identification of peptide sequences, and the evaluation of peptide characteristics in vitro, in silico, in situ, and in vivo. The potential of bioactive peptides suggests useful applications in the prevention and management of diabetes. Furthermore, evidence of clinical studies is necessary for the validation of these peptides’ efficiencies before commercial applications.

Kanthe PS, Patil BS, Das KK. Terminalia arjuna supplementation ameliorates high fat diet-induced oxidative stress in nephrotoxic rats. J Basic Clin Physiol Pharmacol 2021; 33:409-417. [PMID: 33743558 DOI: 10.1515/jbcpp-2020-0106] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Accepted: 01/24/2021] [Indexed: 12/31/2022]
Abstract
OBJECTIVES Dietary high fat possibly causes oxidative stress; also it makes deleterious effect on kidney functions and land up in lipotoxicity in renal tissue. Lipotoxicity is the pathological situation where lipid Peroxidation occurs and generates reactive oxygen species (ROS). Overproduction of ROS than antioxidant present in tissues cause oxidative stress. Terminalia arjuna is found to be potential antioxidant that counteract oxidative stress and possibly maintain glomerular integrity. METHODS Ethanolic extract of T. arjuna (ETO) was prepared and phytochemical analysis was done. Rats were divided into four groups, having six rats in each group as following; group 1-Control (20% fat); group 2 (ETO 100 mg/kg/b.wt); group 3 (30% fat) and group 4 (30% fat + ETO 100 mg/kg/b.wt). Dietary and ETO supplementation were continued for 21 days. Gravimetric, kidney functions (blood urea and serum creatinine) and oxidative stress markers like MDA, SOD and GSH were evaluated. Histopathological analysis was done on kidney along with measurement of glomerular integrity. Morphometrical analysis of glomerular integrity was evaluated by measuring glomerular length, width, glomerular area and Bowman's capsule radius. One way ANOVA was done for analysis of data. RESULTS Blood urea and serum creatinine levels were significantly higher in high fat fed rats indicating renal dysfunction. High fat diet showed significant increase in MDA, decrease in SOD and GSH in rats fed with high fat diet, which indicate generation of oxidative stress. Supplementation of ETO showed amelioratic effect against high fat diet induced renal dysfunction and oxidative stress. Histopathological findings were significantly corroborated with morphometrical analysis of glomerular integrity. CONCLUSIONS Ethanolic extracts of T. arjuna supplementation found to be beneficial against high fat induced renal alterations in terms of functions and architecture.

Abstract
Out of multiple therapeutic targets, DPP-IV is the lead target for the treatment of type 2 diabetes.
Natural products have always been available for the possible lead generation against various diseases
and disorders. In the present review, we have covered various natural sources which have experimentally
validated anti-diabetic activity for type 2 diabetic patients with specific focus on the DPP-IV
inhibition. Out of all, the most potent DPP-IV inhibitors were found to be resveratrol, luteolin, apigenin
and flavone having activity in nanomolar range. Standard drugs like sitagliptin, saxagliptin, and diprotin
A have complex structures as compared to these phenolic compounds. Flavonoids and phenolic compounds
have their added advantages in being present in a number of functional foods and carry antioxidant
properties as well. So, the scientists working on the new chemical entity hunting for the type 2 diabetes
treatment can also explore these natural sources for lead generation.
