5-HT3 Receptor Antagonists (3):

Cat. No. Product Name Effect Purity
  • HY-14564A
    GTS-21 dihydrochloride
    		Antagonist 99.65%
    GTS-21 dihydrochloride is a selective alpha7 nicotinic acetylcholine receptor (α7-nAChR) agonist with anti inflammatory and cognition enhancing activities. GTS-21 dihydrochloride is also a α4β2 (Ki=20 nM for humanα4β2) and 5-HT3A receptor (IC50=3.1 μM) antagonist.
  • HY-103118
    PU02
    		Antagonist 99.76%
    PU02, a derivative of 6-MP (HY-13677), is a negative allosteric modulator (NAM) of 5-HT3 receptor, with IC50 values of 0.36 and 0.73 μM in HEK293 cells transfected with human 5-HT3A and 5-HT3AB receptors respectively.
  • HY-100552
    VUF10166
    		Antagonist 99.83%
    VUF10166 is a potent and high-affinity 5-HT3 receptor antagonist, with Ki values of 0.04 nM (5-HT3A) and 22 nM (5-HT3AB). VUF10166 inhibits 5-HT-induced responses at 5-HT3A and 5-HT3AB receptors at nanomolar concentrations. At 5-HT3 receptor, VUF10166 at higher concentrations also acts as a partial agonist, with an EC50 of 5.2 μM.
