Abstract
Anandamide (AEA) and 2-arachidonoylglycerol (2-AG) are two key players within the endocannabinoid system. Anandamide and 2-AG are lipid neurotransmitters responsible for actions carried out at various receptors, including the cannabinoid receptors. Although these neurotransmitters act within the same system, they differ in biochemical pathways and mechanism of action. Anandamide and 2-AG are both synthesized on demand and have a short-lived transmission. 2-AG is a full agonist at CB1 and CB2 receptors, whereas anandamide is a partial agonist. The endocannabinoid actions at both CB1 and CB2 receptors contribute to the resolution of acute pain. The endocannabinoids also have analgesic benefit to neuropathic, gastrointestinal, inflammatory, and chemotherapy-induced pain. 2-AG has a higher concentration in the nervous tissue and may have a greater role in analgesia and antinociception when compared to anandamide. The endocannabinoid signaling system involving 2-AG and anandamide includes a differential but synergistic role when looking at pharmacological properties.
