(+) -Norfenfluramine (hydrochloride)

(+) -Norfenfluramine hydrochloride, a major hepatic metabolite of (+) -fenfluramine, is a selective 5-HT2B receptor agonist (Ki: 11.2 nM) . (+) -Norfenfluramine hydrochloride potently stimulates the hydrolysis of inositol phosphates and increases intracellular Ca2+. (+) -Norfenfluramine hydrochloride can be used for the research of primary pulmonary hypertension and valvular heart disease[1].
