Formycin A augments insulin release evoked by glucose (5.6 mm or more), this effect not being rapidly reversible. The mechanism responsible for the insulinotropic action of formycin A was investigated in isolated pancreatic islets. It could not be ascribed to facilitation of glucose metabolism. On the contrary, formycin A inhibited glucose oxidation, lowered ATP content, and impaired glucose-stimulated protein biosynthesis. The insulinotropic action of formycin A was apparently attributable to… 

Dynamics of the cationic, bioelectrical and secretory responses to formycin A in pancreatic islet cells

The mode of action of formycin A, or its 5′-triphosphate ester, in islet cells obviously differs from that currently ascribed to endogenous ATP in the process of nutrient-stimulated insulin release.

Regulatory role of adenosine in insulin secretion from pancreatic β-cells—Action via adenosine A1 receptor and beyond

The results of rodent studies indicate that adenosine is present within pancreatic islets and is implicated in the regulation of insulin secretion; however, effects depend onadenosine and glucose concentrations.

Regulation, perturbation, and correction of metabolic events in pancreatic islets

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.

The K+-ATP channel-independent pathway of regulation of insulin secretion by glucose: in search of the underlying mechanism.

It is suggested that among all known potential second messengers, adenine nucleotides are the best candidates as regulators of insulin secretion through the K+-ATP channel-independent pathway.

Nucleolipids of the Nucleoside Antibiotics Formycins A and B: Synthesis and Biomedical Characterization Particularly Using Glioblastoma Cells

It is shown that particularly the formycin A derivative 3b possesses promising antitumor properties in several cancer cell lines with profound cytotoxic effects partly on human glioblastoma cells, with a higher efficacy than the chemotherapeutic drug 5‐fluorouridine.

Pancreatic islet-cell viability, functionality and oxidative status remain unaffected at pharmacological concentrations of commonly used antibioticsin vitro

The results reveal the innocuous nature of the antibiotics used at pharmacological concentrations, suggesting their safety whenever prescribed to combat infections and also during islet isolation procedures.

Effect of tetracycline on pancreas and liver function of adult male albino rats

The results reveal the safe nature of tetracycline with respect to the liver at the lower dose tested, whereas, both the higher and lower doses seem to have detrimental effect on the pancreas as revealed by the rise in free radical levels and decrease in the antioxidant enzyme levels.
