2-MAPB
2-MAPB is a recreational designer drug with empathogenic effects. As with other related substituted benzofuran derivatives such as 6-APB and 5-MAPB, 2-MAPB is a monoamine releaser with some selectivity for serotonin release, generally similar in pharmacological profile to MDMA but with greater activity as a directly acting agonist of 5-HT2 receptor subtypes and somewhat greater toxicity.
