dihydrolycorine

Description

Dihydrolycorine is a derivative of the alkaloid lycorine that has antihypertensive and neuroprotective activities. It inhibits methoxamine-induced contraction of isolated rabbit aortic rings and rat anococcygeus muscle with pA₂ values of 5.93 and 6.35, respectively. Dihydrolycorine reduces mean arterial pressure (MAP) in anesthetized and conscious normotensive rats when administered at a dose of 80 mg/kg. It also reduces electrically or phenylephrine-induced hypertension in pithed rats. Dihydrolycorine reduces infarct size, cerebral edema, and myeloperoxidase activity in a rat model of focal cerebral ischemia-reperfusion injury when administered following reperfusion.

The Uses of dihydrolycorine

Dihydrolycorine is a derivative of Lycorine (L487550), the main phenanthridine Amaryllidaceae alkaloid which exhibits significant antitumor activity in cancer cells that display resistance to proapoptotic stimuli.
