Target	sodium channel[1]
In Vitro	QX-314 bromide exerts biphasic effects on transient receptor potential vanilloid subtype 1 channels (TRPV1) in vitro [1]. QX-314 bromide (1–60 mM) directly activates TRPV1 in a concentration-dependent manner[1]. QX-314 bromide (≥ 30 mM) produces oocyte membrane blackening and cell death [1]. QX-314 bromide inhibits calcium currents in hippocampal CA1 pyramidal neurons intracellular, and the low-threshold (T-type) Ca2+ currents are on average < 10% of control amplitude [3]. QX-314 bromide shifts the current-voltage relationships (I-Vs) in the positive voltage direction due to the presence of intracellular Br- [3].
In Vivo	QX-314 bromide (1.6 mg/kg; i.c.) abolishes responses to noxious mechanical and thermal stimuli without motor or tactile deficits when co-treatment with capsaicin[2]. Animal Model: Male Sprague-Dawley rats (250-290 g)[2] Dosage: 1.6 mg/kg Administration: Intracutaneous injection Result: Abolished responses to noxious mechanical and thermal stimuli without motor or tactile deficits when co-treatment with capsaicin.
