Amfonelic acid (AFA; WIN 25,978) is a research chemical and dopaminergic stimulant with antibiotic properties. Although limited clinical trials have been conducted, it's primarily used in scientific research.[1]
History
The stimulant properties of AFA were discovered serendipitously at
Pharmacology
In studies, it proved to be a potent and highly selective
Despite its different mechanism of action, amfonelic acid displays discriminatory substitution with 150% the stimulant potency of dextroamphetamine.[9] Amfonelic acid has been shown to be neuroprotective against methamphetamine damage to dopamine neurons.[10] It also increases the effects of the antipsychotic drugs haloperidol, trifluoperazine and spiperone.[11] Rats are shown to self-administer amfonelic acid in a dose-dependent manner.[12]
Though AFA was discovered in the course of antibiotic research, there is very little data available on the drug's antimicrobial activity. In 1988, the biologist G.C. Crumplin wrote, "[AFA] is less active against bacteria than are many other 4-quinolones, but studies in our laboratory on selected mammalian cell lines have shown it to be markedly more toxic to these cells than are the 4-quinolones that are more active antibacterial agents. Furthermore, it can be shown that sublethal doses induced marked changes in the pattern of proteins produced by the cell, thus suggesting a possible effect of 4-quinolones on gene transcription in mammalian cells."[13] When evaluated via broth microdilution the MIC of AFA for Escherichia coli is 125 μg/mL, a concentration thirty times higher than the MIC for nalidixic acid in the same E. coli strain.[1]
