Product Description
Alkaloid which exhibits relatively weak antibiotic properties, because of its efflux by multidrug resistance pumps. The antimicrobial action of berberine is potentiated by 5’-methoxyhydnocarpin, a multidrug pump inhibitor. Lowers cholesterol levels through a mechanism different from that of statins. Upregulates the expression of liver low-density lipoprotein receptor (LDLR) resulting in improved clearance of plasma LDL cholesterol through receptor mediated endocytosis. Possesses anti-inflammatory, anti-diabetic and anti-angiogenic effects. Induces apoptosis.

Product Description
ATP-dependent K+ channel blocker in the pancreas, which in turn causes intracellular Ca2+ levels to rise and for insulin to be secreted. Antidiabetic. High affinity binding sites have been identified in the cardiovascular system, the CNS, and pancreatic beta cells. Large potency differences are observed between pancreatic tissue and vascular tissue.

Product Description
Hypolipidemic and antidiabetic agent, shown to reduce adiposity. Induces malic enzyme, mitochondrial glycerol-3-phosphate dehydrogenase, and carnitine palmitoyl transferase I. Inhibitor of citrate lyase and acetyl-CoA carboxylase, expected to disinhibit hepatic fatty acid oxidation while up-regulating electron shuttle mechanism, and thus should stimulate reverse electron transport. Exhibits thyromimetic properties with respect to the modulation of rat liver redox and phosphate potentials.

Product Description
Pioglitazone selectively activates PPARγ-1. It is about one tenth as potent as rosiglitazone (EC50~500nM for human and mouse PPARγ). In a transactivation assay using COS-1 cells transfected with full length human PPARα and RXRα, pioglitazone and rosiglitazone exhibit low level activation of PPARα at 1µM and 5.4- and 4.2-fold activation, respectively, at a concentration of 10µM.

General Information
Thiazolidinediones (TZDs) are a group of structurally related PPARγ agonists with anti-diabetic actions in vivo. Rosiglitazone (Prod. No. ALX-350-103) is a prototypical TZD and has served as a reference compound for this class of PPARγ ligands.
