Sigma Receptor Isoform Comparison

Sigma Receptor Modulators (7):

Cat. No. Product Name Effect Purity
  • HY-108511
    PB28 dihydrochloride
    		Modulator 99.97%
    PB28 dihydrochloride, a cyclohexylpiperazine derivative, is a high affinity and selective sigma 2 (σ2) receptor agonist with a Ki of 0.68 nM. PB28 dihydrochloride is also a σ1 antagonist with a Ki of 0.38 nM. PB28 dihydrochloride is less affinity for other receptors. PB28 dihydrochloride inhibits electrically evoked twitch in guinea pig bladder and ileum with EC50 values of 2.62 μM and 3.96 μM, respectively. PB28 dihydrochloride can modulate SARS-CoV-2-human protein-protein interaction. PB28 dihydrochloride induces caspase-independent apoptosis and has antitumor activity.
  • HY-130344
    SKF 83959
    		Modulator 98.94%
    SKF83959 is a potent and selective dopamine D1-like receptor partial agonist. SKF83959 Ki values for rat D1, D5, D2 and D3 receptors are 1.18, 7.56, 920 and 399 nM, respectively. SKF83959 is a potent allosteric modulator of sigma (σ)-1 receptor. SKF83959 belongs to benzazepine family and has improvements on cognitive dysfunction. SKF83959 can be used for the research of Alzheimer's disease and depression.
  • HY-103412

  • HY-108514
    (±)-PPCC hemioxalate
    		Modulator
    (±)-PPCC hemioxalate is a compound that has the ability to regulate the activity of the sigma-1 receptor. (±)-PPCC hemioxalate can selectively bind sigma-1 protein (s1), and then activate s1 receptor leading to dissociation of s1-BIP complex to regulate ER-mitochondrial calcium signaling, which plays an important role in cell bioenergy and cell survival. (±)-PPCC hemioxalate can be used to study sigma-1 receptors in cocaine addiction, forgetting, pain, depression, Alzheimer's disease, stroke, and cancer.
  • HY-B1733
    Phenyltoloxamine
    		Modulator
    Phenyltoloxamine (Bistrimin) is an antihistamine agent with sedative and analgesic effects. Phenyltoloxamine also has potent Sigma-1 receptor binding affinity (Ki: 160 nM).
  • HY-155484
    SOMCL-668
    		Modulator
    SOMCL-668 is a selective and potent sigma-1 receptor allosteric modulator. ?SOMCL-668 shows positive modulation of improvement in social deficits and cognitive impairment induced by the selective sigma-1 agonist PRE084.?SOMCL-668 displays anti-seizure activities and can be used for psychotic illness research.
