盐酸地布卡因是喹诺酮类衍生物，以靛红为起始物料，经一系列反应可制得盐酸地布卡因。它是一种局部麻醉剂。 Information Dibucaine HCl Dibucaine HCl (Cinchocaine) is a local anesthetics. Targets Sodium channel In vitro Dibucaine (Cinchocaine) HCl is one of the most potent and toxic of the long-acting local anesthetics. Dibucaine (Cinchocaine) HCl blocks both the initiation and conduction of nerve impulses by decreasing the neuronal membrane\'s permeability to sodium ions. This reversibly stabilizes the membrane and inhibits depolarization, resulting in the failure of a propagated action potential and subsequent conduction blockade.
