ETAZOLATE Chemical Properties,Usage,Production

Uses

Antipsychotic.

Uses

Etazolate Hydrochloride is an acyclic nucleotide phosphodiesterase 4 inhibitor, which also exhibits antidepressant-like activity in acute and chronic mouse and rat model of depression.

Biological Activity

etazolate hydrochloride is a pde-4 inhibitor and selective gaba-a receptor modulator [3].pde-4 modulates the release of inflammatory mediators through camp-dependent and -independent mechanisms. selective targeting pde-4 is a novel therapeutic approach in the treatment of inflammation-associated respiratory diseases, such as asthma and copd (chronic obstructive pulmonary disease) [1].in rat neuronal cortical cells, etazolate hydrochloride (0.2 μm) induced sappα through the stimulation of the α-secretase pathway, and exerted a neuroprotective effect against aβ which was associated with sappα induction via the gaba-a receptor [2].in 159 alzheimer’s disease patients, etazolate hydrochloride in combination with one achei (acetycholinesterase inhibitor) was shown to be safe and generally well tolerated in the phase iia study over a 3-month treatment period [3].

Biochem/physiol Actions

Selective inhibitor of cAMP-specific phosphodiesterase.
