A-836339
Based on 1 Customer Validation
A-836339 is a selective CB2 receptor agonist, with Ki values of 0.4 nM and 0.8 nM in humans and rats, respectively. A-836339 exhibits multiple effects such as analgesia, gastric protection, anti-inflammation, and antioxidant activity. A-836339 produces antinociceptive and analgesic activities by activating CB2 receptors in the dorsal root ganglia and spinal cord. A-836339 can also exert gastric protective effects through anti-inflammatory mechanisms (reducing TNF-α and IL-1β) and antioxidant mechanisms (enhancing the activities of CAT and SOD, and reducing H2O2). Radioactively labeled A-836339 can serve as a CB2-specific radioligand for autoradiography and PET imaging. A-836339 can be used in research on inflammatory pain, neuropathic pain, gastric ulcers, cerebral ischemia, etc.
