Cycloheptyl CP 55,940 is a synthetic cannabinoid related to CP 55,940 but is a ring-expanded homologue with a cycloheptyl ring in place of the cyclohexyl ring. It was first synthesized by Pfizer in the 1980s. It falls outside the definition of a "cyclohexylphenol derivative" since it does not have a cyclohexyl ring. Cycloheptyl CP 55,940 has similar potency to CP 55,940 itself, with an ED50 of 0.06 mg/kg in animal studies.
