L-655708, also known as FG-8094, is a nootropic drug. L-655708 acts as a subtype-selective inverse agonist at the α5 subtype of the benzodiazepine binding site on the GABAA receptor. A radiolabelled form of L-655708 was used to map the distribution of the GABAA α5 subtype in the brain. L-655708 was indeed found to produce improved cognitive performance in animal studies, without producing the side effect of convulsions which is produced by non-selective inverse agonists like DMCM.
