Scientific background

5'-Iodoresiniferatoxin (5'-IRTX) is a potent and partial antagonist of the TRPV1 (Vanilloid/capsaicin receptor) channel.1 It is an iodinated form of the potent agonist Resiniferatoxin (#R-400). 5'-Iodoresiniferatoxin partially blocked capsaicin-induced currents in Xenopus oocytes expressing TRPV1 channels (IC50 = 3.9 nM).1 5'-Iodoresiniferatoxin abolished an inhibitory effect of capsaicin on CaV currents (probably mediated by TRPV1) in DRG neurons.
