IsoquinoliniuM, 2,2'-[1,5- pentanediylbis[oxy(3-oxo-3,1- propanediyl)]]bis[1-[(3,4- diMethoxyphenyl)Methyl]-1,2,3,4-tetrahydro-6,7-diMethoxy-2-Methyl-,(1R,1'R,2R,2'R)-

ChEBI: Cisatracurium is a diester that is the (1R,1'R,2R,2'R)-diastereoisomer of atracurium, a quaternary ammonium ion consisting of pentane-1,5-diol with both hydroxy functions bearing 3-[1-(3,4-dimethoxybenzyl)-6,7-dimethoxy-2-methyl-3,4-dihydroisoquinolinium-2(1H)-yl]propanoyl groups. The active species in the skeletal muscle relaxant cisatracurium besylate. It has a role as a muscle relaxant and a nicotinic antagonist. It is a diester and a quaternary ammonium ion.
