O-1871

O-1871 is a potent cannabinoid agonist which was invented by Billy R Martin and Raj K Razdan at Organix Inc in 2002. It has a CB1 receptor affinity of 2.0nM and a CB2 receptor affinity of 0.3nM.[1] Structurally, O-1871 is a cyclohexylphenol derivative related to CP 47,497,[2] and so is illegal in some jurisdictions where CP 47,497 and its derivatives are banned. However the 3,3-dimethylcyclohexyl substituent of O-1871 can be replaced by various other groups, producing other potent compounds such as the cycloheptyl derivative O-1656 and the 2-adamantyl derivative O-1660, as well as the corresponding 3,5-dichlorophenyl derivative,[3] which are not cyclohexylphenol derivatives.
