Dihydrolycorine is isolated from Lycoris radiate Herb with antihypertensive and neuroprotective activities[1]. Dihydrolycorine is an inhibitor of protein synthesis in eukarytic cells by inhibiting the peptide bone formation step[2].
Dihydrolycorine reduces infarct size, cerebral edema, and myeloperoxidase activity in a rat model of focal cerebral ischemia-reperfusion injury when administered following reperfusion[1].Dihydrolycorine inhibits methoxamine-induced contraction of isolated rabbit aortic rings and rat anococcygeus muscle with pA2 values of 5.93 and 6.35, respectively[3].
