5-Fluoro-AET, also known as5-fluoro-α-ethyltryptamine or by the code namePAL-545, is asubstituted tryptaminederivative which acts as aserotonin–dopamine releasing agent (SDRA) and as anagonist of theserotonin5-HT2A receptor.[1]

Pharmacology

Pharmacodynamics

[edit]

ItsEC50Tooltip half-maximal effective concentration values formonoamine release are 36.6 nM for serotonin, 5,334 nM fornorepinephrine, and 150 nM fordopamine in rat brainsynaptosomes.[1] ItsEC50 at the serotonin 5-HT2A receptor is 246 nM and itsEmaxTooltip maximal efficacy at the receptor is 87%.[1]

Several close analogues of 5-fluoro-αET, including5-fluoro-αMT and5-chloro-αMT, are known to be potentmonoamine oxidase inhibitors (MAOIs), specifically ofmonoamine oxidase A (MAO-A).[2] However,α-ethyltryptamine (αET) is a very weak MAOI.[3][4] 5-Fluoro-αET has also more recently been assessed, and in contrast to αET, but similarly to drugs like 5-fluoro-αET, was found to be a potent MAOI, with anIC50Tooltip half-maximal inhibitory concentration of 2,480 nM.[5] Potentmonoamine oxidase inhibition bymonoamine releasing agents (MRAs) has been associated with dangerous and sometimes fataltoxicity in humans.[2]
