ACEA

ChEBI: Arachidonyl-2'-chloroethylamide is a fatty amide obtained by the formal condensation of arachidonic acid with 2-chloroethanamine. It is a potent agonist of the CB1 receptor (Ki = 1.4 nM) and also has a low affinity for the CB2 receptor (Ki = 3100 nM). It has a role as a CB1 receptor agonist, a neuroprotective agent and a CB2 receptor agonist. It is an organochlorine compound, a secondary carboxamide, a fatty amide and a synthetic cannabinoid. It is functionally related to an arachidonic acid.

This synthetic CB1 receptor agonist and anandamide (N- arachidonylethanolamide) analogue (FW = 365.99 g/mol; CAS 220556-69- 4; Symbol: ACEA) is a selective agonist of cannabinoid receptor-1 (Ki = 1.4 nM) but has low affinity to the cannabinoid receptor 2 (Ki = 3.1 μM). ACEA inhibits forskolin-induced cAMP accumulation in Chinese hamster ovary cells expressing the human CB1 receptor. It also increases the binding of [35S]GTPgS to cerebellar membranes and inhibits electrically evoked contractions of the mouse vas deferens. ACEA produces hypothermia in mice, an effect that is inhibited by co-administration of the CB1 receptor antagonist SR141716A.
