Glucose transport across glioblastoma membranes plays a crucial role in maintaining the enhanced glycolysis typical of high-grade gliomas and glioblastoma. We tested the ability of two inhibitors of the glucose transporters GLUT/SLC2A superfamily, indinavir (IDV) and ritonavir (RTV), and of one inhibitor of the Na/glucose antiporter type 2 (SGLT2/SLC5A2) superfamily, phlorizin (PHZ), in decreasing glucose consumption and cell proliferation of human and murine glioblastoma cells. We found in vitro that RTV, active on at least three different GLUT/SLC2A transporters, was more effective than IDV, a specific inhibitor of GLUT4/SLC2A4, both in decreasing glucose consumption and lactate production and in inhibiting growth of U87MG and Hu197 human glioblastoma cell lines and primary cultures of human glioblastoma...

In view of the occurrence of diabetic ketoacidosis associated with the use of sodium-glucose transport protein-2 (SGLT2) inhibitors in patients with type 1 diabetes (T1DM) and the relative absence of this complication in patients treated with liraglutide in spite of reductions in insulin doses, we investigated the effect of liraglutide on ketogenesis. Twenty-six patients with inadequately controlled T1DM were randomly divided into two groups of 13 patients each. After an overnight fast, patients were injected, subcutaneously, with either liraglutide 1...

Diabetic ketoacidosis is an infrequent but life-threatening acute complication of diabetes, affecting predominantly patients with type 1 diabetes, children, and pregnant women, where ketosis is usually associated with marked hyperglycemia. Recently, an increasing number of cases have been reported of euglycemic diabetic ketoacidosis in patients with type 2 diabetes receiving sodium-glucose cotransporter 2 inhibitor treatment in routine practice. There is a minor, but not negligible diabetic ketoacidosis risk associated with this drug class, which was not seen in randomized clinical trials...

This review provides mechanistic insight in the pleiotropic effects of sodium-glucose transporter-2 (SGLT-2) inhibitors with particular interest to the pathophysiology of heart failure. The SGLT-2 inhibitor empagliflozin has recently demonstrated an unprecedented 38% reduction in cardiovascular mortality in patients with diabetes. Despite modest effects on long-term glycemic control, highly significant reductions in heart failure admissions and end-stage kidney disease were observed. SGLT-2 inhibitors are the latest approved class of glucose-lowering agents...

In this paper, we review the results of large, double-blind, placebo-controlled randomized trials mandated by the US Food and Drug Administration to examine the cardiovascular safety of newly-approved antihyperglycemic agents in patients with type 2 diabetes. The cardiovascular effects of dipeptidyl peptidase-4 (DPP-4) inhibitors remain controversial: while these drugs did not reduce or increase the risk of primary, pre-specified composite cardiovascular outcomes, one DPP-4 inhibitor (saxagliptin) increased the risk of hospitalization for heart failure in the overall population; another (alogliptin) demonstrated inconsistent effects on heart failure hospitalization across subgroups of patients, and a third (sitagliptin) demonstrated no effect on heart failure...

Diabetic kidney disease is the leading cause of end-stage renal disease, a significant contributor to cardiovascular (CV) disease, responsible for much of the morbidity and mortality in patients with type 2 diabetes (T2DM). Strategies to slow or prevent the onset and progression of diabetic kidney disease are critical for effectively managing T2DM and reducing CV risk. Sodium-glucose cotransporter 2 (SGLT2) inhibitors are effective antidiabetic agents, which may provide nephroprotective and CV protective effects...

Despite type 2 diabetes (T2D) management offers a variety of pharmacological interventions targeting different defects, numerous patients remain with persistent hyperglycaemia responsible for severe complications. Unlike resistant hypertension, treatment resistant T2D is not a classical concept although it is a rather common observation in clinical practice. Areas covered: This article proposes a definition for 'treatment resistant diabetes', analyses the causes of poor glucose control despite standard therapy, briefly considers the alternative approaches to glucose-lowering pharmacotherapy and finally describes how to overcome poor glycaemic control, using innovative oral or injectable combination therapies...

Sodium-glucose cotransporter 2 (SGTL2) inhibitors are a novel class of antihyperglycemic agents that work in an insulin-independent manner by promoting urinary glucose excretion. In addition to efficacious glucose lowering, they exert beneficial effects on blood pressure and weight while avoiding hypoglycemia unless combined with insulin or insulin secretagogues. This review explores the mechanism of action of SGLT2 inhibitors, their effects on glycated hemoglobin, weight, blood pressure and hypoglycemia, potential adverse effects, renal considerations and cardiovascular outcomes...

Caring for patients with type 2 diabetes mellitus (T2DM) has entered an era with many recent additions to the regimens used to clinically control their hyperglycemia. The most recent class of agents approved by the Food and Drug Administration (FDA) for T2DM is the sodium-glucose-linked transporter type 2 (SGLT2) inhibitors, which work principally in the proximal tubule of the kidney to block filtered glucose reabsorption. In the few years attending this new class arrival in the market, there has been a great deal of interest generated by the novel mechanism of action of SGLT2 inhibitors and by recent large outcome trials suggesting benefit on important clinical outcomes such as death, cardiovascular disease and kidney disease progression...

Diabetic kidney disease not only has become the leading cause for ESRD worldwide but also, highly contributes to increased cardiovascular morbidity and mortality in type 2 diabetes. Despite increased efforts to optimize renal and cardiovascular risk factors, like hyperglycemia, hypertension, obesity, and dyslipidemia, they are often insufficiently controlled in clinical practice. Although current drug interventions mostly target a single risk factor, more substantial improvements of renal and cardiovascular outcomes can be expected when multiple factors are improved simultaneously...

BACKGROUND: Accumulation of epicardial fat (EF) is associated with increased cardio-metabolic risks and coronary events, independently of traditional cardiovascular risk factors. Therefore, the reduction of EF volume (EFV) may be associated with reduced cardio-metabolic risks and future cardiovascular events. Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce body fat including visceral fat and cardiovascular events in patients with type 2 diabetes. However, it has still been unknown whether SGLT2 inhibitors can reduce EFV...

PURPOSE OF REVIEW: Guidelines for a standard second diabetes medication for the treatment of type 2 diabetes (T2DM) have yet to be established. The rapid increase in the number of newer therapies available makes the choice more difficult. Thus, we reviewed clinical trial evidence evaluating newer therapies available for treatment intensification beyond monotherapy. RECENT FINDINGS: Head-to-head studies comparing newer therapies versus traditional (i.e., sulfonylurea) approaches consistently find lower incidence of hypoglycemia and weight gain with newer therapies...

Ten-week-old ZDF rats at an early stage of diabetes embody metabolic characteristics of obese type 2 diabetic patients, severe insulin and glucose intolerance in muscle and liver, excessive postprandial excursion of plasma glucose and insulin, and a loss of metabolic flexibility with decreased lipid oxidation. Metabolic flexibility and glucose flux were examined in Zucker diabetic fatty (ZDF) rats during fasting and near normal postprandial insulinemia and glycemia after correcting excessive postprandial hyperglycemia by treatment with sodium-glucose co-transporter 2 inhibitor (SGLT2-I) for 7 days...

AIMS: Insulin resistance and impaired insulin secretion are cardinal defects that contribute to hyperglycemia in type 2 diabetes. Recently, a new class of drugs called sodium-glucose linked transporter 2 (SGLT2) inhibitors has been introduced that reduce blood glucose by inhibiting glucose reabsorption in the kidney and is not dependent on glucose metabolism or insulin action. The purpose of the present study was to determine whether the excretion of glucose would improve insulin resistance, impaired insulin secretion or both...

BACKGROUND: Physiologic determinants, such as pulse pressure [difference between systolic blood pressure (SBP) and diastolic BP (DBP)], mean arterial pressure (2/3 DBP + 1/3 SBP), and double product [beats per minute (bpm) × SBP], are linked to cardiovascular outcomes. The effects of canagliflozin, a sodium glucose co-transporter 2 (SGLT2) inhibitor, on pulse pressure, mean arterial pressure, and double product were assessed in patients with type 2 diabetes mellitus (T2DM). METHODS: This post hoc analysis was based on pooled data from four 26-week, randomized, double-blind, placebo-controlled studies evaluating canagliflozin in patients with T2DM (N = 2313) and a 6-week, randomized, double-blind, placebo-controlled, ambulatory BP monitoring (ABPM) study evaluating canagliflozin in patients with T2DM and hypertension (N = 169)...

Currently available antihyperglycemic agents, despite being effective, provide inadequate glycemic control and/or are associated with side effects or nonadherence. Canagliflozin, a widely used orally active inhibitor of sodium-glucose cotransporter 2 (SGLT2), is a new addition to the therapeutic armamentarium of glucose-lowering drugs. This review summarizes findings from different clinical and observational studies of canagliflozin 300 mg in patients with type 2 diabetes mellitus (T2DM). By inhibiting SGLT2, canagliflozin reduces reabsorption of filtered glucose, thereby increasing urinary glucose excretion in patients with T2DM...

Maintaining the integrity of cellular membranes is critical to protecting metabolic activities and genetic information from the environment. Regulation of transport across membranes of essential chemicals, including water, nutrients, hormones and many drugs, is therefore key to cellular homeostasis and physiological processes. The two main transporter superfamilies are ATP-binding cassette (ABC) transporters that primarily function as efflux transporters, and the solute carrier (SLC) transporters. SLC transporters encompass 52 gene families with almost 400 different human transporter genes...

Sodium-glucose linked transporter 2 (SGLT2) inhibitors are a new and promising class of antidiabetic agents which target renal tubular glucose reabsorption. Their action is based on the blockage of SGLT2 sodium-glucose cotransporters that are located at the luminal membrane of tubular cells of the proximal convoluted tubule, inducing glucosuria. It has been proven that they significantly reduce glycated hemoglobin (HbA1c), along with fasting and postprandial plasma glucose in patients with type 2 diabetes mellitus (T2DM)...
