    Sodium-glucose co-transporter inhibitor dapagliflozin attenuates cognitive deficits in sporadic Alzheimer’s rat model

    © 2022 Marmara University Press.Alzheimer’s disease (AD) and Type 2 Diabetes Mellitus (T2DM) are both characterized by similar pathologies, and studies have shown that various drugs from both groups may be effective in another. The effects of sodium-glucose co-transporter (SGLT)2 inhibitors in AD are unknown. According to molecular docking studies, various SGLT inhibitors have acetylcholinesterase (AChE) inhibition activity, which is therapeutic target for AD. In this study, we investigated the effects of SGLT2 inhibitor dapagliflozin on intracerebroventricular (icv) streptozotocin (STZ) induced sporadic AD rats using open field test (OFT), novel object recognition test (NORT), passive avoidance test (PAT) and Morris’s water maze test (MWMT). Rats were randomly divided into 4 groups: vehicle-control, icv STZ, dapagliflozin, and galantamine treatments groups. STZ was injected bilaterally in two divided doses on day 1 and 3. All treatments began on day 1 and continued to day 21. OFT was performed for evaluating animal locomotor activity and anxiety. Other behavioral tests, NORT, PAT, and MWMT was performed for determining of learning and memory ability of rats. On day 21, all rats were decapitated. Our results showed that treatments with dapagliflozin and galantamine significantly prevented learning and memory deficits in behavioral tests. Dapagliflozin may present as a potent dual inhibitor of SGLT2 and AChE. Our results may form the basis of future dual treatment against diabetes and diabetes-related neurological diseases. The effects of possible dual AChE and SGLT2 inhibition by a single compound may help to establish new drugs that perform both anti-AD and antidiabetic action.

    The methanolic extracts of Teucrium polium L. and Micromeria fruticosa (L.) Druce subsp. brachycalyx P. H. Davis improve diabetes in streptozotocin/nicotinamide-induced type 2 diabetic female Sprague Dawley rats
    (2023-12-01) ÇAM, MUHAMMET EMİN; YAVUZ, AYŞE NUR; TAŞKIN, TURGUT; KABASAKAL, LEVENT; ELÇİOĞLU, HATİCE KÜBRA; Sermet S., ÇAM M. E., YAVUZ A. N., TAŞKIN T., Kabatas G. S., YAZIR Y., KABASAKAL L., ELÇİOĞLU H. K.
    Background: Teucrium polium and Micromeria fruticosa subspecies are known to be used in traditional medicine for diabetes treatment. Objective: The present study aimed to examine the potential antidiabetic effects and the mechanisms of antidiabetic actions of Teucrium polium L. methanolic extract (TP) and Micromeria fruticosa (L.) Druce subsp. brachycalyx P. H. Davis methanolic extract (MF) on rats with type 2 diabetes mellitus (DM). Methods: Streptozotocin (STZ) and nicotinamide (NA) were injected intraperitoneally to induce type 2 diabetes mellitus (T2DM) in rats. Plant extracts’ antidiabetic mechanisms of action were investigated with biochemical analyses and histopathological analyses performed. Results: TP and MF treatments reduced the blood glucose levels compared to the untreated diabetic rats. TP reduced TNF-α levels in serum, increased insulin levels in serum and pancreas, reduced SGLT-2 levels in kidneys, reduced GLUT-2 levels in the ileum; and MF reduced TNF-α levels, and increased insulin levels in serum and pancreas, increased GLP-1 levels, and reduced GLUT-2 levels in the ileum, and reduced SGLT-2 levels in kidneys. Treatments improved the histopathological results in the pancreas, kidney, and liver. Conclusions: The results presented in this study demonstrated that TP and MF both have potential antidiabetic effects and may be effective in T2DM treatment.
