MedKoo CAT#: 524183

CAS#: 444912-75-8

Description: AM-2233 is a highly potent full agonist for the cannabinoid receptors. It was developed as a selective radioligand for the cannabinoid receptors and has been used as its 131I derivative for mapping the distribution of the CB1 receptor in the brain. AM-2233 was found to fully substitute for THC in rats, with a potency lower than that of JWH-018 but higher than WIN 55,212-2.
