| Katalog-Nr.GC15434 |
A 839977 ist ein P2X7-selektiver Antagonist; es blockiert den durch BzATP hervorgerufenen Calciumeinstrom an rekombinanten P2X7-Rezeptoren von Mensch, Ratte und Maus (IC50-Werte sind 20 nM, 42 nM bzw. 150 nM) und reduziert entzÜndliche und neuropathische Schmerzen in Tiermodellen; Die antihyperalgetischen Wirkungen der P2X7-Rezeptorblockade werden durch die Blockierung der Freisetzung von IL-1beta vermittelt.

A839977 is a novel and selective antagonist of P2X7 receptor with the IC50 values of 20 nM, 42nM and 150nM for human, rat and mouse, respectively [1].
A839977 has been reported to block BzATP-evoked changes in intracellular calcium concentrations in 132N1 cells stable expressing P2X7 receptors with the IC50 values of 20 nM, 42nM and 150nM for human, rat and mouse, respectively. In addition, A839977 has also revealed to inhibit BzATP-stimulated IL-1β release and YO-PRO uptake with the IC50 of 37nM and 7nM, respectively, in differentiated human THP-1 cells. Besides, A839977 has been noted to produce parallel rightward shifts in BzATP concentration-effect calcium influx curves with the pAα value of 8.1. Apart from these, A839977 has been exhibited to reduce CFA-induced thermal hyperalgesia in a dose-dependent fashion with the ED50 value of 100μmol/kg(i.p.) [1].
