PRL-8-53: the whole record
Few compounds this widely discussed have less published about them. The complete record for PRL-8-53 is two documents, both from its inventor, Nikolaus R. Hansl:
- US patent 3,870,715 (filed 1973, granted 1975), "Substituted amino ethyl meta benzoic acid esters". It describes rat maze and shock-avoidance tests, isolated-ileum spasmolytic tests, and rodent toxicology for the compound series. It calls them "cholinergic and spasmolytic agents".
- One 1978 paper in Psychopharmacology (Hansl & Mead), a small double-blind study.
A PubMed search for PRL-8-53 returns that one paper. We found no independent replication, no receptor-binding study and no later research.
What it is
Methyl 3-[2-[benzyl(methyl)amino]ethyl]benzoate, a small benzoate ester with a benzylmethylamino-ethyl side chain.
| Hydrochloride | Free base | |
|---|---|---|
| Formula | C18H22ClNO2 | C18H21NO2 |
| MW | 319.8 g/mol | 283.4 g/mol |
| CAS | 51352-87-5 | 51352-88-6 |
| PubChem CID | 70700868 | 39989 |
Mechanism
Unknown. The patent's "cholinergic" label rests on a gut-muscle (ileum) assay. Mechanisms you may see elsewhere, such as dopamine or serotonin effects, have no primary source.
What we sell
30 capsules of 5 mg per bottle (size 1 HPMC capsules with microcrystalline cellulose). No certificate of analysis is posted for PRL-8-53 yet, so this page quotes no purity figure and doesn't say which salt form the lot is.
