The plasma concentration of C20 sphingomyelin is decreased in men with prostate cancer.

Peroxisome proliferator-activated receptors (PPARs) α, δ, γ are ligand-activated nuclear transcription factors involved in the regulation of energy homeostasis as well as insulin sensitivity and glucose metabolism. Pharmacologies of PPARδ receptor agonists, though relatively obscure, have recently been reported to elevate high-density lipoprotein (HDL) cholesterol and lower plasma triglyceride (TG) levels in obese insulin resistant rhesus monkeys.

In a transactivation assay using human PPAR receptors, CAY10592 acts as a selective partial PPARδ agonist (EC50 = 53 nM) with no effect on PPARα or PPARγ activity up to 30 μM. Chronic treatment of high fat fed ApoB100/CETP-transgenic mice with CAY10592 at a dose of 20 mg/kg increases HDL levels, decreases LDL and TG levels, and improves insulin sensitivity.

The truncated glucagon-like peptides GLP-1(7-37) is naturally occurring peptide product of the preproglucagon gene that are synthesized primarily in the intestine and acts as incretin that are released from the intestine into the bloodstream in response to food and stimulate insulin secretion. GLP-1(7-37) produced a dose-related enhancement of the glucose-stimulated increase in plasma insulin concentration and an increased rate of glucose infusion in Sprague-Dawley Rats at a dosing rang of 0.5, 5, or 50 pmol min kg. Further, infusion of GLP-1(7-37) for 60 mins produced a small transitory increase in plasma insulin concentration in fasted rats and fed rats and a slight transitory decrease in plasma glucose concentration. Moreover, GLP-1(7-37) (5 pmol min kg IV) infusion for 6 h in Sprague-Dawley rats produced a sustained increase in plasma insulin concentration relative to levels in rats infused with vehicle[1].

Piragliatin, also known as RO4389620, is a glucokinase activator. Piragliatin greatly enhances glucose-induced pancreatic islet respiration and insulin release. Piragliatin lowers plasma glucose both in the postabsorptive state and after a glucose challenge in patients with type 2 diabetes mellitus. Piragliatin has an acute glucose-lowering action in patients with mild type 2 diabetes, mainly mediated through a generalized enhancement of β-cell function and through fasting restricted changes in glucose turnover.

Gliclazide-d4 is intended for use as an internal standard for the quantification of gliclazide by GC- or LC-MS. Gliclazide is a sulfonylurea and an inhibitor of pancreatic β-cell ATP-sensitive potassium (KATP) channels.

Gliclazide (5 and 10 μg/ml) reduces LDL oxidation by human aortic smooth muscle cells (HASMCs), decreasing TBARS content and 8-isoprostane levels. It also decreases oxidized LDL-induced HASMC proliferation and monocyte adhesion when used at concentrations ranging from 1 to 10 μg/ml. Gliclazide (5 mg/kg) reduces serum glucose levels and increases glucose uptake by isolated rat hindquarters in a model of diabetes induced by streptozotocin (STZ).
