Description
(extracted from source data)
DESCRIPTION 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. (GtoPdb)
DESCRIPTION Etazolate hydrochloride (SQ 20009) is an orally active, selective inhibitor of type 4 phosphodiesterase (PDE4) with an IC50 of 2 ¦ÌM. Etazolate hydrochloride is a ¦Ã-aminobutyric acid A (GABAA) receptor regulator. Etazolate hydrochloride is an ¦Á-secretase activator and induced the production of soluble amyloid precursor protein (sAPP¦Á). Etazolate hydrochloride, a pyrazolopyridine class derivative, increases cAMP levels. Etazolate hydrochloride has anxiolyticlike, antidepressant-like and anti-inflammatory effects[1][2][3][4][5].
