diMethyl lithosperMate B Chemical Properties,Usage,Production

Chemical Properties

White crystalline powder, soluble in organic solvents such as methanol, ethanol, DMSO, etc., derived from Salvia miltiorrhiza.

Uses

Dimethyl lithospermate B (dmLSB) is a selective Na+ channel agonist. Dimethyl lithospermate B slows inactivation of sodium current (INa), leading to increased inward current during the early phases of the action potential (AP)[1][2].
