F-2, also known as 6-(2-aminopropyl)-5-methoxy-2-methyl-2,3-dihydrobenzofuran or as benzofuran-2-methyl-5-methoxy-6-(2-aminopropane), is a chemical compound and possible psychedelic drug of the phenethylamine, amphetamine, and benzofuran families.[1] It is the derivative of 6-APDB with a methyl group at the 2 position and a methoxy group at the 5 position of the benzofuran ring system.[1]

Use and effects

In his book PiHKAL (Phenethylamines I Have Known and Loved), Alexander Shulgin lists F-2's dose as greater than 15 mg orally and its duration as unknown.[1] The drug produced no effects at assessed doses of up to 15 mg.[1] Higher doses were not tested.[1] It is unknown whether F-2 is active.[1] On the other hand, David E. Nichols reported in 1981, via personal communication with Shulgin and M. Trampota in 1980, that F-2 was "shown to possess clinical activity".[2]

Pharmacology

Pharmacodynamics

F-2 has been found to substitute for the psychedelic drug DOM in drug discrimination tests in rats.[1][3][4] However, it was about 40-fold less potent than DOM in this regard, requiring a dose of 5 mg/kg.[1] For comparison, F-2 was tested in humans at doses of only up to 0.2 mg/kg.[1] In contrast to the case of rats, F-2 at doses of up to 100 mg/kg intraperitoneally in mice was without effects.[1] A dose of 150 mg/kg intraperitoneally in mice was lethal.[1]

Chemistry

Synthesis

The chemical synthesis of F-2 has been described.[1]

Analogues

Analogues of F-2 include DOPR, 6-APDB, MMDA-2, F (F-1), and F-22, among others.[1]

History

F-2 was first described in the scientific literature by David E. Nichols in 1981 via personal communication with Alexander Shulgin and M. Trampota in 1980.[2] Subsequently, it was described in greater detail by Nichols and colleagues in 1986[3] and 1991[4] and by Shulgin in his book PiHKAL (Phenethylamines I Have Known and Loved) in 1991.[1] Shulgin briefly alluded to F and its derivatives in a paper in 1971.[5]
