FSCPX is a potent and selective irreversible antagonist of A1 adenosine receptor (A1AR), with low nanomolar potency for binding to the A1AR. FSCPX could modify the effect of NBTI, a nucleoside transport inhibitor, by reducing the interstitial adenosine level in the guinea pig atrium[1][2].
FSCPX irreversibly blocks the binding of [3H]-8-cyclopentyl-1,3dipropylxanthine ([3H]DPCPX), with an IC50 of 11.8±3.2 nM in DDT1 MF2 cells[1].
FSCPX (20 μM; 48 h) attenuates protection from necrosis and apoptosis in A1AR-overexpressing LLC-PK1 cells[3].
FSCPX (2-20 μM; 48 h) reverses the upregulation of HSP27 mRNA and protein in A1AR-overexpressing LLC-PK1 cells without an effect on the mRNA or protein for HSP70[3].
