体外研究:
QX-314 bromide exerts biphasic effects on transient receptor potential vanilloid subtype 1 channels (TRPV1) in vitro .QX-314 bromide (1–60 mM) directly activates TRPV1 in a concentration-dependent manner.QX-314 bromide (≥ 30 mM) produces oocyte membrane blackening and cell death .QX-314 bromide inhibits calcium currents in hippocampal CA1 pyramidal neurons intracellular, and the low-threshold (T-type) Ca2+ currents are on average QX-314 bromide 相关抗体:
