Special Issue Information

Dear Colleagues,

Diabetes mellitus and its complications are one of the major health challenges of our time. Currently, more than 400 million adults are affected, a number that is expected to increase to 600 million people within the next two decades. Type 2 diabetes mellitus, or non-insulin dependent diabetes mellitus, is the most common type and its initial stages are treated with oral antidiabetics. Though antihyperglycemic agents with different mechanisms of action are commercially available, their adverse events and hepato-renal toxicity are pronounced. Thus, the discovery of new and safer medicines is urgently warranted.

Natural drug products have always been an important source of bioactives and drugs derived from nature still account for half of today’s approved therapeutics. This Special Issue, “Antidiabetic Drugs from Natural Resources”, is dedicated to the discovery of new antidiabetic lead compounds from nature. Research articles and reviews dealing with novel antidiabetic activities of natural products and/or natural sources of antidiabetics are therefore very welcome. Additionally, the evaluation of extracts and herbal preparations used for the treatment of diabetes mellitus by modern analytical techniques will be considered.

Background:Ganoderma lucidum (Leyss. Ex. Fr) Karst is a basidiomycete mushroom that has been used for many years as a food supplement and medicine. In Brazil, National Health Surveillance Agency (ANVISA) classified Ganoderma lucidum as a nutraceutical product. The objective of the present work was to observe the effects of an extract from Ganoderma lucidum in rats treated with streptozotocin, and an agent that induces diabetes. Method: Male Wistar rats were obtained from the animal lodging facilities of both University Nove de Julho (UNINOVE) and Lusiada Universitary Center (UNILUS) with approval from the Ethics Committee for Animal Research. Animals were separated into groups: (1) C: Normoglycemic control water; (2) CE: Normoglycemic control group that received hydroethanolic extract (GWA); (3) DM1 + GWA: Diabetic group that received extract GWA; and (4) DM1: Diabetic group that received water. The treatment was evaluated over a 30-day period. Food and water were weighted, and blood plasma biochemical analysis performed. Results: G. lucidum extract contained beta-glucan, proteins and phenols. Biochemical analysis indicated a decrease of plasma glycemic and lipid levels in DM rats induced with streptozotocin and treated with GWA extract. Histopathological analysis from pancreas of GWA-treated DM animals showed preservation of up to 50% of pancreatic islet total area when compared to the DM control group. In plasma, Kyn was present in diabetic rats, while in treated diabetic rats more Trp was detected. Conclusion: Evaluation from G. lucidum extract in STZ-hyperglycemic rats indicated that the extract possesses hypoglycemic and hypolipidemic activities. Support: Proj. CNPq 474681/201. Full article
