Diabetes mellitus (DM) is a chronic disease caused by inherited or acquired deficiency in insulin secretion and by decreased insulin secretion by the organ. Insulin deficiency causes the DM. Synthetic drugs are widely used in the treatment of diabetes, but they have some side effects. The antihyperglycemic and antihyperlipedemic effects of the plants are related to their ability to maintain pancreatic function. Medicinal plants constituents such as glycosides, alkaloids, terpenoids, and flavonoids mitigate DM. B. ciliata inhibits the α-glucosidase and α-amylase. Cinnamon extracts improve insulin receptor function by activating insulin receptor kinase and inhibiting insulin receptor phosphatase, which lead to an increase in insulin sensitivity. Morinda lucida also had the highest antioxidant activity, and it also inhibited the α-glucosidase. Many plants have also been shown to antihyperlipedemic effects. Finally, it can be concluded that medicinal plants have that ability to treat or prevent DM.

Antidiabetic Plants

Abnormally emanates from difficulty in insulin secretion, Diabetes mellitus (DM) is known to be a metabolic disorder that causes an increase of blood glucose in blood streams. The lack of effective modern treatments, the lifelong treatment with modern medicines, overtime, its associated health side effects, and its expensive prices among others are the challenging existing realities that devastate the health and economic burdens its sufferers, especially in developing nations. Today, this has prompted the search for cheap, safe, and reliable drugs from medicinal plants. This study reviewed existing information on medicinal plants used for the treatment of diabetes mellitus from various sources. Several documents (published and unpublished papers, books among others) were consulted in compilation of this review. It is found that there is a wide, yet uneven support for active components of major medicinal.

This study examined the in vivo effects of Echinops spp. polysaccharide B on type 2 diabetes mellitus in Sprague-Dawley rats. We constructed a type 2 diabetes mellitus Sprague-Dawley rat models by feeding a high-fat and high-sugar diet plus intraperitoneal injection of a small dose of streptozotocin. Using this diabetic rat model, different doses of Echinops polysaccharide B were administered orally for seven weeks. Groups receiving Xiaoke pill and metformin served as positive controls. The results showed that Echinops polysaccharide B treatment normalized the weight and blood sugar levels in the type 2 diabetes mellitus rats, increased muscle and liver glycogen content, improved glucose tolerance, increased insulin secretion, and reduced glucagon and insulin resistance indices. More importantly, Echinops polysaccharide B treatment upregulated the expression of insulin receptor in the liver, skeletal muscles, and pancreas, and significantly improved the expression levels of insulin receptor substrate-2 protein in the liver and pancreas, as well as it increased insulin receptor substrate-1 expression in skeletal muscles. These two proteins play crucial roles in increasing insulin secretion and in controlling type 2 diabetes mellitus. The findings of the present study suggest that Echinops polysaccharide B could improve the status of diabetes in type 2 diabetes mellitus rats, which may be achieved by improving insulin resistance. Our study provides a new insight into the development of a natural drug for the control of type 2 diabetes mellitus.

Indian Medicinal Plants

Diabetes Mellitus is the most prevalent metabolic disorder which has made it a major health threat worldwide. The available synthetic drugs for the cure of Diabetes mellitus are associated with high cost, various side effects and several limitations. Medicinal plants are the rich depots of the phytochemicals which can be useful for the treatment of chronic disorders. These plants are the better alternative to chemical drugs causing less or no harm to the body. Several plants are traditionally known for their antidiabetic properties but the detail investigation of their active molecules is required in order to be developed as therapeutic drug. Therefore, the present review aims to provide comprehensive information on various Indian medicinal plants, their constituents and mechanism of action for the cure of diabetes mellitus.

Common Target

Purpose. Diabetes mellitus is characterized by hyperglycemia resulting from defects in insulin secretion, action or both. The use of medicinal plants for the treatment of diabetes mellitus dates back from the Ebers papyrus of about 1550 B.C. One of the major problems with herbal drugs is that the active ingredients are not well defined. It is important to know the active components and their molecular interactions which will help to analyze their therapeutic efficacy and also to standardize the product. There are a number of medicinal plants known for their anti-diabetic effect that possess similarities in their active chemical components, e.g. iridoid and secoiridoid glycosides. Methods. In this study, we have compared the structure of various iridoid and secoiridoid glycosides to design a novel pharmacophore. We further developed a structure-activity relationship for the inhibition of glycogen phosphorylase-a. Conclusion. By using docking studies, we are proposing, for the first time, that inhibition of glycogen phosphorylase-a activity is a common target for iridoids and secoiridoids to elicit anti-diabetic effects. This article is open to POST-PUBLICATION REVIEW.

Insulin Receptor Kinase

The regulatory role of GTP-binding proteins (G-proteins) in insulin receptor function was investigated using isolated insulin receptors and plasma membranes from rat adipocytes. Treatment of isolated insulin receptors with 1 mM-guanosine 5′-[gamma-thio]triphosphate (GTP[S]) inhibited insulin-stimulated phosphorylation of the beta-subunit, histone Hf2b and poly(GluNa4,Tyr1) by 22%, 65% and 65% respectively. Phosphorylation of calmodulin by the insulin receptor kinase was also inhibited by 1 mM-GTP[S] both in the absence (by 88%) and in the presence (by 81%) of insulin. In the absence of insulin, 1 mM-GTP had the same effect on calmodulin phosphorylation as 1 mM-GTP[S]. However, when insulin was present, GTP was less effective than GTP[S] (41% versus 81% inhibition). Concentrations of GTP[S] greater than 250 microM are necessary to inhibit phosphorylation. Although these concentrations are relatively high, the effect of GTP[S] is not due to competition with [32P]ATP for the insulin receptor kinase since (1) other nucleotide triphosphates did not inhibit phosphorylation as much as did GTP[S] (or GTP) and (2) the Vmax of the ATP-dependent kinase reaction was decreased in the presence of GTP[S]. GTP[S] (1 mM) also inhibited insulin binding to isolated receptors and plasma membranes, by 80% and 50% respectively. Finally, an antibody raised to a peptide sequence common to the alpha-subunits of G-proteins Gs, Gi, Go and transducin detected G-proteins in plasma membranes but failed to detect them in the insulin receptor preparation. These results indicate that GTP inhibits insulin receptor function, but does so through a mechanism that does not require a conventional GTP-binding protein.
