Arachidonylcyclopropylamide (ACPA) is an analog of N-arachidonylethanolamine and a selective agonist of the CB1 (cannabinoid receptor1) (Ki = 2.2 nM). The compound has displayed marked selectivity for the CB1 receptor over the CB2 receptor by 325 fold. ACPA is described to inhibit forskolin-induced accumulation of cAMP in hamster ovary cells, and to increase cerebellar membrane binding of [35S]GTPγS. APCA is also described to produce a dose-dependent increase in microglial BV-2 cell migration. Agonism of the CB1 receptor by ACPA shows effects on GABAergic inhibitory neurotransmission, demonstrating an inhibition of GABAergic synaptic transmission onto superficial and deep medial entorhinal neurons.
