Description: High affinity and selective CB2 inverse agonist
Chemical Name: 5-(4-Chloro-3-methylphenyl)-1-[(4-methylphenyl)methyl]-N-[(1S,2S,4R)-1,3,3-trimethylbicyclo[2.2.1]hept-2-yl]-1H-pyrazole-3-carboxamide
Purity: ≥98% (HPLC)
Biological Activity
High affinity and selective CB2 inverse agonist (Ki = 0.6 nM). Exhibits >700-fold selectivity for CB2 over CB1 receptors. Blocks the effects of CP 55,940 (Cat. No. 0949) on forskolin-sensitive adenylyl cyclase activity and MAPK in CHO cells expressing CB2 receptors. Also blocks CP 55,940-induced B-cell activation. Orally bioavailable.

Epilepsy Poster
Epilepsy is a brain disease that affects 60 million people globally. More than 20 anti-seizure drugs are currently available, but these do not address the underlying causes of the condition. This poster summarizes current knowledge about the development of the condition and highlights some approaches that have disease-modifying effects in proof-of-concept studies.
