A-796260 is a compound that acts as a potent and selective cannabinoid CB2 receptor agonist. The analgesic effects of A-796260 on activity-induced pain behavior were evaluated in a rat model, the results demonstrated that A-796260 may be a useful new pharmacological compound for further studying CB2 receptor pharmacology and for evaluating its role in the modulation of pain.

A-412,997 or A-412997 is a highly selective agonist for the dopamine D4 receptor. In animal tests, it improved cognitive performance to a similar extent as methylphenidate, but without producing place preference or other signs of abuse liability. When dosed systemically, A-412997 crossed the blood brain barrier rapidly. It was suggested, that selective activation of the D4 receptor, A-412997, might represent a target for the treatment of attention deficit hyperactivity disorder without the potential drug abuse liability associated with current psychostimulant therapies.
