AM-2233

AM-2233 is a drug that acts as a highly potent full agonist for the cannabinoid receptors, with a K_i of 1.8 nM at CB₁ and 2.2 nM at CB₂ as the active (R) enantiomer.^[1] 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.^{[2][3][4][5][6][7]} 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.^[8]
