5-EAPB (1-(benzofuran-5-yl)-N-ethylpropan-2-amine) is a potentially entactogenic amphetamine which is structurally related to 5-MAPB and 5-APB. It might be predicted to show similar effects to these drugs in humans, but the pharmacology of 5-EAPB remains unstudied as of 2020.

5-EAPB is similar in structure to compounds such as 5-APB which are claimed to be agonists of the 5-HT_2C receptor^[2] as well as a triple monoamine reuptake inhibitor, however 5-EAPB is not listed as an example in this patent, and it is not yet established to what extent the activity of 5-EAPB resembles that of 5-APB.

Legality[edit]

In the UK, all benzofurans are considered Class B drugs^[3] and are therefore illegal.

5-EAPB is listed in the Fifth Schedule of the Misuse of Drugs Act (MDA) and therefore illegal in Singapore as of May 2015.^[4]

Adverse reactions and deaths[edit]

Three people in their 30s were hospitalised after each taking approximately 500 mg of 5-EAPB, one of whom later died in hospital, whilst attending Brownstock music festival in Essex, UK on August 31, 2013.^[5]
