Cannabinoid inhibition of adenylate cyclase. Biochemistry of the response in neuroblastoma cell membranes.

“The inhibition of adenylate cyclase activity by cannabimimetic compounds in a membrane fraction from cultured neuroblastoma cells has been examined. The inhibition was shown to be concentration-dependent over a nanomolar range for both delta 9-tetrahydrocannabinol and its synthetic analog…

This study points to the similarities between the enzyme inhibition by cannabimimetic compounds and by muscarinic cholinergic compounds. It is inferred that the cannabimimetic compounds must act via regulatory mechanisms similar to those operating for receptor-mediated inhibition of adenylate cyclase.”
