Chemical Properties
White Solid
Uses
8-Cyclopentyl-1,3-dipropylxanthine has been used as an adenosine receptor (A1AR) antagonist in macrophages and human umbilical vein endothelial cells (HUVECs). It has also been used as A1AR antagonist in MCF-7 breast cancer cell line to test its anti-cancer effect.
Uses
DPCPX is a potent and very selective A1-adenosine receptor antagonist, with a Ki of 0.46 nM for A1 receptors in rat whole-brain membranes. Its 740-fold A1-selectivity is the highest reported for an adenosine antagonist
Definition
ChEBI: An oxopurine that is 7H-xanthine substituted at positions 1 and 3 by propyl groups and at position 8 by a cyclohexyl group.
Biological Activity
Potent and selective A 1 adenosine receptor antagonist, both in vitro and in vivo . K i values are 3.9, 130, 50 and 4000 nM for human A 1 , A 2A , A 2B and A 3 receptors respectively.
Biochem/physiol Actions
8-Cyclopentyl-1,3-dipropylxanthine (DPCPX) is a selective A1?adenosine receptor antagonist. DPCPX possesses anti-cancer functionality. It induces apoptosis in breast cancer cells and favors mRNA expression of caspases.
