O-1656 is a cannabinoid agonist which was invented by Billy R Martin and Raj K Razdan at Organix Inc in 2002. It is moderately selective for the CB₂ receptor with a CB₁ receptor affinity of 18 nM and a CB₂ receptor affinity of 2 nM.^[1]^[2]^[3] Since it has a cycloheptyl ring attached to the phenol core, it falls outside the definition of a "cyclohexylphenol derivative", but may still be controlled by generic legislation in some jurisdictions.
