ACPA is primarily used in research settings to study the endocannabinoid system due to its role as a potent and selective agonist of the CB1 receptor. It helps in understanding the physiological and pathological processes mediated by CB1 receptors, such as pain modulation, appetite regulation, and neuroprotection. ACPA is also utilized in preclinical studies to explore its potential therapeutic effects in conditions like chronic pain, anxiety, and neurodegenerative diseases. Its ability to activate CB1 receptors makes it a valuable tool for investigating cannabinoid signaling pathways and developing novel pharmacological treatments.
