Etazolate (SQ-20,009, EHT-0202) is an anxiolytic drug which is a pyrazolopyridine derivative and has unique pharmacological properties.[1] [2] [3] It acts as a positive allosteric modulator of the GABAA receptor at the barbiturate binding site,[4] [5] [6] [7] as an adenosine antagonist of the A1 and A2 subtypes,[8] and as a phosphodiesterase inhibitor selective for the PDE4 isoform.[9] [10] [11] It is currently in clinical trials for the treatment of Alzheimer's disease.[12]
