The dimethyl esters of succinic acid (SAD) and glutamic acid (GME) were found to be efficiently metabolized in colon carcinoma cells of the Caco-2 line. The rate of [1,4-14C]SAD and [2,3-14C]SAD conversion to radioactive acidic metabolites, CO2, amino acids, pyruvic

Glutamic acid dimethyl ester (GME; 3.0-10.0 mM) enhanced insulin release evoked by 6.0-8.3 mM D-glucose, 1.0-10.0 mM L-leucine, or 5.0-10.0 mM 2-amino-bicyclo(2,2,1)heptane-2-carboxylic acid, causing a shift to the left of the sigmoidal relationship between insulin output and D-glucose concentration. In

We investigated if the therapeutic switching of sofalcone (SFC), a gastroprotective agent, to an anticolitic agent is feasible using colon-targeted drug delivery. SFC can activate the anti-inflammatory nuclear factor (erythroid-derived 2)-like 2 (Nrf2)-hemeoxygenase-1 (HO-1) pathway in human colon epithelial cells

An elevated level of endoplasmic reticulum (ER) stress is considered an aggravating factor for inflammatory bowel disease (IBD). To develop an ER-stress attenuator that is effective against colitis, 4-phenylbutyric acid (4-PBA), a chemical chaperone that alleviates ER stress, was conjugated

Ampullae of Lorenzini isolated from the skate (Raja clavata) have been investigated in vitro electrophysiologically to determine the nature of the transmitter at the synapse between the electroreceptor cells and afferent fibres. Glutamic acid diethyl ester (GDEE), glutamic acid dimethyl

The dimethyl ester of L-glutamic acid (DMG) stimulates insulin release and was proposed as a possible insulinotropic tool in the treatment of non-insulin-dependent diabetes. In such a perspective, it was investigated whether DMG enhances the B-cell secretory response to GLP-1

This study aimed to compare the metabolic and secretory responses of pancreatic islets from animals with non-insulin-dependent diabetes to D-glucose with the effects of the methyl esters of succinic acid (SME) and glutamic acid (GME). The insulin secretory response to

The insulinotropic action of the meglitinide analogues KAD-1229, A-4166 and repaglinide was examined in rat pancreatic islets deprived of exogenous nutrient or incubated in the presence of nutrient secretagogues such as D-glucose and the methyl esters of pyruvic acid, succinic

Electrical stimulation of fimbria-fornix (fi-fx) fibers monosynaptically activated many of the neurons tested in the lateral septal complex (LSC) of the rat. The orthodromically activated LSC neurons were classified as "strongly" orthodromically activated (SOA) or "weakly" orthodromically activated ( WOA

The dimethyl ester of L-glutamic acid (GME) stimulates insulin release in isolated pancreatic islets and may represent a novel experimental tool in the study of non-insulin-dependent diabetes. In the present study, GME was found both to stimulate insulin secretion and

We used a hemolytic plaque assay for insulin to determine whether the same pancreatic B cells respond to D-glucose, 2-amino-bicyclo[2,2,1]heptane-2-carboxylic acid (BCH) and the association of this nonmetabolized analogue of L-leucine with either the monomethyl ester of succinic acid (SME)

It is intriguing that the kinetics of glucose-stimulated insulin secretion from the in situ perfused pancreas differ between the rat and the mouse. Here we confirm that insulin release in the rat is clearly biphasic, whereas in the mouse glucose

Bacillus anthracis is a lethal agent of anthrax disease and the toxins are required in anthrax pathogenesis. The anthrax lethal toxin can trigger NLRP1b inflammasome activation and pyroptosis. Although the underlying mechanism is well understood, the medications targeting the NLRP1b

Methyl pyruvate and the dimethyl ester of L-glutamic acid were administered intravenously, as a primed constant infusion (1.0-2.0 micromol followed by 0.5-1.0 micromol/min, both expressed per gram of body wt), in adult rats that had been injected with streptozotocin during
