Sigma 2 Receptor Antagonists (6):

Cat. No. Product Name Effect Purity
  • HY-111669
    CT1812
    		Antagonist
    CT1812 (Sigma-2 receptor antagonist 1) is an orally active and brain penetrant sigma-2 receptor antagonist with a Ki of 8.5 nM. CT1812 can be used for the research of Alzheimer’s disease.
  • HY-18099
    S1RA
    		Antagonist 99.43%
    S1RA (E-52862) is a highly selective σ1 receptor (σ1R) antagonist with Kis of 17 nM and 23.5 nM for human σ1R and guinea pig σ1R, respectively. S1RA has Moderate antagonistic activity for human 5-HT2B receptor (Ki= 328 nM). S1RA has antinociceptive effects in neuropathic pain models. S1RA prevents mechanical and cold hypersensitivity in Oxaliplatin (HY-17371)-treated mice.
  • HY-14222
    UMB24
    		Antagonist
    UMB24 is a potent antagonist of σ2 receptor, with Ki values of 170 nM anf 322 nM for σ2 receptor and σ1 receptor, respectively. UMB24 attenuats cocaine-induced convulsions and locomotor activity, but not lethality.
  • HY-149855
    AB10
    		Antagonist
    AB10 is a selective S1R antagonist. AB10 with Ki of 10, 165 nM for S1R and S2R, respectively. AB10 reverses the effect of Capsaicin (HY-10448) caused pain in model.
  • HY-149854
    AB21
    		Antagonist
    AB21 is a potent and selective S1R antagonist with Kis of 13, 102 nM for S1R and S2R. AB21 has the effect of reducing mechanical hypersensitivity.
  • HY-108513
    σ1 Receptor antagonist 4
    		Antagonist
    σ1 Receptor antagonist 4 (compound TC1) is a selective sigma1 (σ1) receptor antagonist with a Ki of 10 nM. σ1 Receptor antagonist 4 is weakly active at σ2 receptor (Ki of 370 nM) and has no activity at dopamine (DAT), serotonin (SERT), and norepinephrine (NET) transporters.
