Background:
Mesaconitine is the main active component of genus aconitum plants.IC50 value:Target: in vitro: In HUVECs, 30 microM mesaconitine increased the [Ca(2+)](i) level in the presence of extracellular CaCl(2) and NaCl, and the response was inhibited by KBR7943. Mesaconitine increased intracellular Na(+) concentration level in HUVECs. The [Ca(2+)](i) response by mesaconitine was inhibited by 100 microM D-tubocurarine [1]. Mesaconitine at 30 microM inhibited 3 microM phenylephrine-induced contraction in the endothelium-intact, but not endothelium-denuded, aortic rings [2]. MA promoted the alpha-MT-induced decrease in NE levels in hippocampus, medulla oblongata plus pons and spinal cord [3].
