(S)-1-(3-Trifluoromethylphenyl)-2-aminopropane

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

ChEBI: (2S)-1-[3-(trifluoromethyl)phenyl]-2-propanamine is a member of amphetamines.

5-HT_2B Receptor: 11.2 nM (Ki); 5-HT_2A Receptor: 1516 nM (Ki); 5-HT_2C Receptor: 324 nM (Ki)
