The CGS 15943, with the CAS registry number 104615-18-1, is also known as [1,2,4]Triazolo[1,5-c]quinazolin-5-amine,9-chloro-2-(2-furanyl)-. It belongs to the product category of Adenosine receptor. This chemical's molecular formula is C₁₃H₈ClN₅O and molecular weight is 285.69. What's more, its systematic name is 9-Chloro-2-(2-furyl)[1,2,4]triazolo[1,5-c]quinazolin-5-amine. This chemical is a non-xanthine triazoloquinazoline adenosine antagonist. It has the advantage over most xanthine derivatives that it is not a phosphodiesterase inhibitor, and so has more a specific pharmacological effects profile. It produces similar effects to caffeine in animal studies, though with higher potency.
