Analogues of glucose labeled with 123 iodine in positions 1, 2 or 3 have been synthesized. The aim of this study was to examine their biological behavior in four experimental models in order to assess whether they could be used to evaluate the uptake of glucose with single photon emission computed tomography (SPECT). The results obtained have shown that none of these molecules enters the cell using the glucose transporter. Therefore, they cannot be used as tracers of glucose uptake.

Background: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are established treatment options for type 2 diabetes (T2D). In addition to their glycemic benefit, GLP-1 RAs also induce weight loss by suppressing appetite via hypothalamic pathways. However, it remains unclear whether weight reduction is the primary driver of glycemic improvement.

GPR119 has emerged as a promising target for treating type 2 diabetes and associated obesity, as its stimulation induces the secretion of glucagon-like peptide-1 and glucose-dependent insulinotropic peptide in the intestinal tract as well as the glucose-dependent release of insulin in pancreatic β-cells. We describe the design and synthesis of novel GPR119 agonists containing a 1,4-disubstituted cyclohexene scaffold. Compound displayed nanomolar potency (EC = 3.

Background: Anesthesia can significantly impact positron emission tomography (PET) neuroimaging in preclinical studies. Therefore, understanding these effects is crucial for accurate interpretation of the results. In this experiment, we investigate the effect of [F]-labeled glucose analog fluorodeoxyglucose ([F]FDG) uptake in the brains of rats anesthetized with two commonly used anesthetics for rodents: isoflurane, an inhalation anesthetic, and Hypnorm-Dormicum, a combination injection anesthetic.

(), an edible brown alga, is rich in isophloroglucin A (IPA) phlorotannin compounds and is effective in preventing diseases, including diabetes. We evaluated its anti-glycation ability, intracellular reactive oxygen species scavenging activity, inhibitory effect on the accumulation of intracellular MGO/MGO-derived advanced glycation end products (AGE), and regulation of downstream signaling pathways related to the AGE-receptor for AGEs (RAGE) interaction. IPA (0.

Diabetic wounds with chronic infections present a significant challenge, exacerbated by the growing issue of antimicrobial resistance, which often leads to delayed healing and increased morbidity. This study introduces a novel silver-zinc oxide-eugenol (Ag+ZnO+EU) nanocomposite, specifically designed to enhance antimicrobial activity and promote wound healing. The nanocomposite was thoroughly characterized using advanced analytical techniques, confirming its nanoscale structure, stability and chemical composition.
