Gomisin J increases NO bioavailability by activating eNOS, regulates lipid metabolism by activating the AMPK pathway, inhibits fetuin-A and NF-κB to exert anti-inflammatory effects, and activates Nrf2/HO-1 to enhance antioxidant capacity. Gomisin J has the activities of anti-hypertension, regulating liver lipid metabolism, and reducing cerebral ischemia-reperfusion injury, and can be used for research on hypertension, non-alcoholic fatty liver disease, cerebral ischemia-reperfusion injury, etc.

High density lipoprotein (human) (HDL (human)) is a human-derived high-density lipoprotein. High density lipoprotein can cross the blood-brain barrier, and partially acts on endothelial nitric oxide synthase (eNOS) by activating surface receptors such as SR-B1 and S1P3R, as well as intracellular signaling cascades involving Akt, PI3K and MAPK, thereby inducing the production of NO in endothelial cells. High density lipoprotein (human) can be used in research related to type 2 diabetes, Alzheimer's disease, cancer and atherosclerosis.
