Unifiram (DM-232) is an ampakine-like drug derived from biarylpropylsulfonamide,[1] and has antiamnesic and other effects in animal studies with up to a thousand times higher potency than piracetam.[2][3] A number of related compounds are known, including sunifiram (DM-235).[4][5][6] Unifiram has two enantiomers, with (R)-(+)-unifiram (dextrounifiram) being the more active isomer.[7] Unifiram is shown to reduce the duration of hypnosis induced by pentobarbital, without impairing motor coordination.[8]

Unifiram is not patented and, despite the lack of long-term toxicity studies, it is commonly sold online.[9]

(R)-(+)-unifiram (dextrounifiram).
(R)-(+)-unifiram (dextrounifiram).

Safety

As of 2015, no formal human studies with unifiram have been conducted.

Some 12 years after their disclosure (2000) I casually found that on the web, there were dozens of sites offering Unifiram and Sunifiram as drugs that improve cognition in healthy individuals even if only few preclinical studies were done and their long-term toxicity was unknown.
