[Definition]

ChEBI:Etazolate is a pyrazolopyridine that is 1H-pyrazolo[3,4-b]pyridine which is substituted at positions 1, 4, and 5 by ethyl, 2-isopropylidenehydrazino, and ethoxycarbonyl groups, respectively. A phosphodiesterase IV inhibitor with antidepressant and anxiolytic properties. It has a role as a neuroprotective agent, an antipsychotic agent, a phosphodiesterase IV inhibitor, an anxiolytic drug, an antidepressant, an alpha-secretase activator and a GABA agent. It is a hydrazone, an ethyl ester and a pyrazolopyridine.
