FSCPX | CAS#156547-56-7 | A1 adenosine receptor antagonist

MedKoo Cat#: 563600 | Name: FSCPX

Description:

WARNING: This product is for research use only, not for human or veterinary use.

FSCPX irreversible A1 adenosine receptor antagonist. FSCPX inhibits the effects of NBTI that are mediated by increasing the interstitial concentration of adenosine of endogenous (but not exogenous) origin. FSCPX (5 microM) completely reversed the increase in K+ current of guinea pig atrial myocytes caused by 100 microM adenosine (259 +/- 30 to 20 +/- 7 pA) but had no significant effect on K+ currents caused by either 0.5 microM carbachol or 100 microM GTP gamma S.
