GtoPdb Ligand ID: 7336

Synonyms: EHT-0202 | SQ 20009
Compound class: Synthetic organic
Comment: Has anxiolytic effects as positive allosteric modulator of the GABAA receptor at the barbiturate binding site, as an adenosine antagonist of the A1 and A2 receptor subtypes and as a phosphodiesterase inhibitor selective for the PDE4 isoform. It is currently in clinical trials for the treatment of Alzheimer's disease with a possible MMOA of upregulating alpha-secretase activity.

Bioactivity Comments
Multiple molecular modes of action have been reported for etazolate but these are not established as polypharmacology for any individual in vivo effect. Reports suggest that one of these, selective GABAA receptor modulation, stimulates alpha-secretase and consequent sAPPalpha production in rodents [1] .
