DOYN, also known as 4-ethynyl-2,5-dimethoxyamphetamine, is a serotonergic psychedelic of the phenethylamine, amphetamine, and DOx families.[1][2][3] According to Daniel Trachsel, it produces hallucinogenic effects with a dose range of 2 to 6 mg orally and a duration of 10 to 15 hours.[1] The drug's effects are described as typical psychedelic effects including fantasy, imagery, and visuals.[1] It is described as having a relatively short duration compared to 4-alkyl DOx derivatives like DOM, perhaps due to more rapid metabolism.[1] DOYN was first mentioned in the scientific literature by Trachsel in 2003 and was then described in more depth by him in 2013.[1][2][3] It is a controlled substance in Canada under phenethylamine blanket-ban language.[4]

Als Alkinderivat existiert das DOYN (33) als einziger Vertreter. Die Synthese erfolgte in Analogie zu Ref. [411. Es zeigt typische psychedelische Wirkungen begleitet von Fantasy, Imagery und Visuals (Siche Kapitel 8.5.18 für Begriffserklärung) im Bereich von 2—6mg gepaart von einer Wirkdauer von 10—15h. Diese Wirkdauer ist — im Vergleich zu den 4-alkylierten Analoga — eher kurz. Es darf auf einen etwas rascheren Metabolismus (im Bereich der Dreifachbindung) im Vergleich zu DOET (14) spekuliert werden. Das als biphasisch beschriebene Wirkprofil deutet auf aktive Metaboliten hin.
