Application

Neferine has been used to study its effect in autophagy signalling.

Biochem/physiol Actions

Neferine is a bis-benzylisoquinoline alkaloid isolated from the green seed embryos Nelumbo Nucifera Gaertn (Lotus) that displays multiple pharmacological activities including anti-tumor, antidepressant-like and antiarrhythmic actions. Recent studies shown that neferine potently inhibits proliferation of human osteosarcoma cells while is low-toxic on non-neoplastic human osteoblast cells. Apparently in U2OS cells, neferine stabilizes p21 through the activation of p38 MAPK, which leads to G1 cell cycle arrest. Also, neferine inhibits Ang II-induced HUVSMC proliferation by upregulation of HO-1.

MAPKs

The mitogen-activated protein kinase (MAPK) family consists of both stress activated (SAPK) and mitogen-activated (MAPK) protein kinases. They form a network of signal transduction cascades that mediate cellular responses to a diverse range of stimuli, including growth factors, chemical or osmotic stress, irradiation, bacterial infection and proinflammatory cytokines.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
