In perifused pancreatic islets from euglycemic rats, the secretory response to either glibenclamide or glimepiride (1.0 microM each) increases as a function of the concentration of D-glucose (2.8-16.7 mM) present in the perifusion medium. On the contrary, the sulfonylurea-induced increment in 45Ca efflux from prelabeled islets decreases at increasing concentrations of the hexose. Neither glibenclamide nor glimepiride affect D-glucose metabolism in isolated islets, as judged from the production… Expand
Enhancement by succinic acid dimethyl ester of insulin release evoked by D-glucose and glimepiride in the perfused pancreas of normoglycemic and hyperglycemic rats.
TLDR
SAD indeed displays favourable attributes for stimulation of insulin release in type 2 diabetes, with emphasis on its insulinotropic efficiency at high concentrations of D-glucose in an animal model of B-cell glucotoxicity. Expand
Stimulation of insulin secretion and potentiation of glibenclamide-induced insulin release by the dimethyl ester of glutamic acid in anaesthetized rats.
TLDR
It is proposed that GME represents a novel tool to bypass anomalies of glucose transport and metabolism in the beta cell and, hence, to stimulate insulin release and enhance the insulinotropic action of hypoglycaemic sulphonylurea in animal models of non-insulin-dependent diabetes. Expand
Effect of N-[(trans-4-isopropylcyclohexyl)-carbonyl]-D-phenylalanine on nutrient catabolism in rat pancreatic islets.
TLDR
Findings indicate that the insulinotropic action of A-4166 is not attributable to any sizeable increase in the metabolism of exogenous or endogenous nutrients. Expand
The esters of carboxylic nutrients as insulinotropic tools in non-insulin-dependent diabetes mellitus.
TLDR
Espers of carboxylic nutrients, such as succinic or glutamic acid, present the advantages of stimulating both proinsulin biosynthesis and insulin release, remaining efficient in models of B-cell glucotoxicity, augmenting the secretory response to hypoglycemic pharmacological agents, protecting the B- cell against cytotoxic aggressions, and exerting a long-term beneficial effect upon thesecretory potential of the endocrine pancreas. Expand
Alterations in net glucose uptake and in the pancreatic B-cell GLUT2 transporter induced by diazoxide and by secretory stimuli.
TLDR
GLUT2 and glucose uptake in the pancreatic B-cell are modified by the secretory process, which suggests that changes in the glucose transporter have a functional role in normal B- cell physiology. Expand
In vitro and in vivo effects of new insulin releasing agents.
TLDR
The results indicate that appropriate structural modification can generate isosteres of glibenclamide with different features and activity profiles, and that BM 225 was more potent and acting faster than BM 208. Expand
Regulation, perturbation, and correction of metabolic events in pancreatic islets
TLDR
In terms of pathology, attention is drawn to the deficiency of FAD-linked mitochondrial glycerophosphate dehydrogenase and the potential usefulness of hypoglycemic sulfonylureas and meglitinide analogs, adenosine Analogs, non-glucidic nutrients, and GLP-1 is underlined. Expand
The beta cell in NIDDM: giving light to the blind
TLDR
It is proposed that the methyl esters of succinic acid and related molecules may represent new tools with which to bypass defects in glucose transport, phosphorylation and further catabolism and, hence, to stimulate both proinsulin biosynthesis and insulin release in NIDDM. Expand
Potentiation of the insulinotropic and hypoglycemic action of gliquidone by succinic acid esters.
TLDR
These findings indicate that it is possible to design esters of succinic acid that are devoid of the risk of generating methanol by intracellular hydrolysis, and yet susceptible to increase both the insulinotropic and hypoglycemic responses to antidiabetic agents. Expand
Tolbutamide potentiates the volume-regulated anion channel current in rat pancreatic beta cells
TLDR
Tolbutamide can induce beta cell electrical activity by potentiating the glucose- and volume-regulated anion channel current, which could be secondary to a metabolic action in the beta cell. Expand

Metabolic, cationic and secretory effects of hypoglycemic sulfonylureas in pancreatic islets
TLDR
It is concluded that the insulinotropic effect of hypoglycemic sulfonylureas cannot be merely equated to a facilitation of nutrient metabolism or inactivation of phosphodiesterase in the islet cells. Expand
Cationic and secretory effects of glimepiride and glibenclamide in perifused rat islets.
TLDR
D dissociated behaviours suggest that the insulinotropic action of hypoglycemic sulfonylureas is not necessarily attributable solely to a primary decrease in K+ conductance. Expand
Interference of glycogenolysis with glycolysis in pancreatic islets from glucose-infused rats.
TLDR
It is proposed that the interference of glycogenolysis with glycolysis in pancreatic islets from glucose-infused rats participates in the paradoxical changes in insulin output which represent a typical feature of B-cell glucotoxicity. Expand
Metabolic effects and fate of succinate esters in pancreatic islets.
TLDR
It is proposed that a concerted increase of both succinate and acetyl residue influx into the Krebs cycle accounts for the increase in O2 uptake caused by the succinate methyl esters and, hence, for stimulation of both pro-insulin biosynthesis and insulin release. Expand
Respiratory, ionic, and functional effects of succinate esters in pancreatic islets.
TLDR
It is concluded that the respiratory, cationic, biosynthetic, and secretory responses of the islets to succinate methyl esters display the characteristic features usually encountered in the process of nutrient-stimulated insulin release. Expand
Hexose metabolism in pancreatic islets: unequal oxidation of the two carbons of glucose-derived acetyl residues.
TLDR
The present results indicate that the oxidation of glucose-derived acetyl residues relative to their generation in the reaction catalyzed by pyruvate dehydrogenase is higher than that estimated from the ratio between D-[6-14C]glucose and D-[3,4- 14C] glucose conversion to 14CO2. Expand
Stimulation by D-glucose of mitochondrial oxidative events in islet cells.
TLDR
The findings emphasize the importance of distal regulatory processes in the control of D-glucose catabolism in normal islet cells, and document the perturbation of such processes in a model of dysfunction for this fuel-sensor organ. Expand
Perturbation of pancreatic islet function in glucose-infused rats.
TLDR
The secretory behavior of insulin- and glucagon-producing cells was found to be perturbed in isolated perfused pancreases removed from rats infused with hypertonic solutions of glucose for 48 hours, and it is proposed that the latter anomaly may play a role in the altered dynamics of insulin release found in animals or patients with long-term hyperglycemia.

The Stimulus‐Secretion Coupling of Glucose‐Induced Insulin Release VIII. Combined Effects of Glucose and Sulfonylureas *
TLDR
The data suggest that the insulinotropic action of sulfonylureas results from the accumulation of calcium in the beta cell, and the subsquent activation of the microtubular‐microfilamentous system involved in the emiocytosis of insulin secretory granules. Expand
Hexose metabolism in pancreatic islets. Feedback control of D-glucose oxidation by functional events.
TLDR
It is demonstrated that in pancreatic islets it is possible to dissociate both glycolysis from mitochondrial oxidative events and the oxidation of acetyl residues from their generation rate, and the experimental data suggest that nutrient-responsive and ATP-requiring functional processes exert a feedback control on mitochondrial respiration in this fuel-sensor organ.
