Salvinorin B

Salvinorin B is a selective and brain-penetrant kappa opioid receptor (KOPr) agonist with an EC50 of 248 nM and Ki of 2.95 μM. Salvinorin B activates downstream signaling pathways by binding to KOPr, inhibits pain transmission and reduces inflammatory response. Salvinorin B can be used for the researches of inflammation, immunology and neurological disease, such as neuropathic pain, multiple sclerosis and anxiety[1][2][3][4][5].
