Anti-diabetic Potential Mechanisms of Phytomedicines – A Review
![](https://www.texilajournal.com/thumbs/article/0947.jpg)
Abstract:
Diabetic mellitus is an endocrine disorder characterized by hyperglycemia, polyphagia, polyuria, and polydipsia. In this condition, the cells and tissues are unable to utilize glucose for energy due to inadequate insulin secretion. The complications of the disease include diabetic retinopathy, diabetic neuropathy, and diabetic nephropathy that affect the eyes, nerves, kidneys and stroke, renal failure, and heart attacks are other serious consequences of diabetes. The conventional modern medicines for treatment are oral hypoglycemic drugs, sulfonylureas and glinides, metformin and thiazolidinedione, dipeptidyl peptidase-4 (DPP4) inhibitors, and injections such as GLP-1 agonists. Due to the presence of a lot of side effects, the modern world is now turning to bioactive chemical components synthesized from plants. Today, drugs derived from herbs or plants are widely used because of the exploitation of specific compounds and their therapeutic actions. Various phytochemicals have notable and significant mechanisms for reducing the blood glucose level. These natural agents can have a protective and therapeutic effect on diabetes mellitus through cellular mechanisms such as the regeneration of pancreatic β cells, antioxidative stress, and intracellular signalling transduction pathways. The present study aims to review the mechanisms of various phytochemicals that play a role in antidiabetic activity. The possible mechanisms by which the antidiabetic herbs act are α-glucosidase inhibitors, PPAR activators, free radical scavengers, HMG Co suppressors, regenerators of beta cells, and cause an increase in insulin secretion and glycogen synthesis in glycemic control.References:
