2,5-Dimethoxy-4-butylamphetamine

2,5-Dimethoxy-4-butylamphetamine (DOBU) is a lesser-known psychedelic drug and a substituted amphetamine. DOBU was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), only low dosages of 2–3 mg were tested, with the duration simply listed as "very long". DOBU produces paresthesia and difficulty sleeping, but with few other effects. Compared to shorter chain homologues such as DOM, DOET and DOPR which are all potent hallucinogens, DOBU has an even stronger 5-HT2 binding affinity but fails to substitute for hallucinogens in animals or produce hallucinogenic effects in humans, suggesting it has low efficacy and is thus an antagonist or weak partial agonist at the 5-HT2A receptor.
