8-Cyclopentyl-1,3-dimethylxanthine（Cat No.:R000590）, also known as CPX, is a xanthine derivative and a selective antagonist of the adenosine A1 receptor. It is a potent and specific inhibitor of the A1 receptor, which plays a role in regulating neurotransmitter release, neuronal excitability, and vascular tone. CPX is used in research to study the physiological and pharmacological effects of blocking the A1 receptor. It has been investigated for its potential therapeutic applications in conditions such as epilepsy, pain, and neurodegenerative disorders.
