Some Common Antidiabetic Plants of the Indian Subcontinent

A Review of Anti-hyperglycemic Effects of Curry Leaf Tree (Murraya koenigii)

Diabetes mellitus is becoming a metabolic disease that is defined by the level of hyperglycemia. Nowadays, it has a serious threat to public healthiness in throughout the world. Constituents and extracts isolated from diverse natural resources, mainly plants, have constantly been a rich store for controlling and treating diabetes problems. Numerous researches are ongoing to identify the suitable traditional medical drugs, medicinal herbs, and resources for managing this condition. Murraya koenigii Spreng (family Rutaceae) is commonly known as a ‘curry leaf tree’ locally. It is widely scattered in India and Sri Lanka, and leaves are commonly used for cooking. And also mainly used for various health conditions such as diabetes, anemia, diarrhea, and others. The present review aimed to critically review the anti-hyperglycemic effect of the M. koenigii based on the review, in vitro, in vivo, and clinical studies. Based on this review, the M. koenigii possess flavonoids, phenols, saponins, alkaloids, tannins, and cardiac glycosides. It has shown a potential anti-hyperglycemic effect on induced diabetic rats. This review reported the potential of M. koenigii and its extract to be a high-value dietary product in terms of its anti-hyperglycemic effects and industrial profits. Therefore, the present review supports the researchers and readers/users to realize the importance of using M. koenigii in managing diabetes mellitus. Further, this review provides a valuable document for future scientific-related clinical trials in diabetic patients.

Natural Antidiabetic Agents: Molecular Docking Study using the Extra Precision Method

Background:

Diabetes mellitus (DM) is the most severe, chronic metabolic disorder with abnormally elevated concentration of plasma glucose levels, leading to significant complications, such as diabetic neuropathy, retinopathy, and cardiovascular illnesses.

Objective:

Synthetic drugs have some disadvantages and limitations. Therefore, there is a continuous global and insisting need for new and better treatment options for Diabetes Mellitus.

Methods:

In this study, 42 natural anti-diabetic constituents like alkaloids, glycosides, and flavonoids were selected on the basis of mechanism of action on various molecular targets such as Glucokinase activator, Dipeptidyl peptidase 4 (DPP-4), peroxisome proliferator-activated receptors (PPARγ), and α-glucosidase inhibitor. To investigate the potential molecular targets for natural antidiabetcs agents, molecular docking study was carried out using the Glide module of Schrodinger Suit.

Results:

Interactions of specific amino acid of the targets with the atoms of the chemical constituents and their Gscore indicate the proper binding of chemical constituents with target. The results revealed that Myricetin, Quercetin ae interacts with active sites of the target chosen and can be used for the designing of novel compounds as anti-dibetics.

Conclusion:

Calculated GScore could be used as a preliminary tool for screening of anti-diabetic drugs before performing experimental activity.

Antidiabetic Potential of Medicinal Plants and Their Active Components

Diabetes mellitus is one of the major health problems in the world, the incidence and associated mortality are increasing. Inadequate regulation of the blood sugar imposes serious consequences for health. Conventional antidiabetic drugs are effective, however, also with unavoidable side effects. On the other hand, medicinal plants may act as an alternative source of antidiabetic agents. Examples of medicinal plants with antidiabetic potential are described, with focuses on preclinical and clinical studies. The beneficial potential of each plant matrix is given by the combined and concerted action of their profile of biologically active compounds.
