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
Immunosuppressant. Potent inhibitor of NF-κB activation in T cells, with an almost complete inhibition at 200nM. Suppresses cytokine production (IFN-γ, TNF-α, IL-2 and IL-4) and inhibits NF-AT in peripheral blood T cells at concentrations that do not impair NF-κB and AP-1 activities. In contrast to the immunosuppressant cyclosporin A (Prod. No. ALX-380-002), rocaglamide does not inhibit calcineurin phosphatase activity. Induces apoptosis.
