          Background

          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].
