Reparixin is a potent inhibitor of both CXCL8 receptors?CXCR1/2, it inhibits weakly?CXCR2-mediated cell migration (IC50=100 nM), whereas it strongly blocks?CXCR1-mediated chemotaxis (IC50=1 nM).

CB1 inverse agonist 1 (MRL-650) is an orally active and selective CB1 agonist. The IC50s for CB1 and CB2 are 7.5 nM and 4100 nM, respectively.

Tetrahydrocannabivarin is a neutral cannabis receptor subtype (CB1) receptor antagonist, it can increases neural responding to rewarding and aversive stimuli, this effect profile suggests therapeutic activity in obesity, perhaps with a lowered risk of depressive side effects. Tetrahydrocannabivarin exhibits anticonvulsant effects in a piriform cortical brain slice model of epileptiform activity.
