Sigma Receptor Modulator

PB28 dihydrochloride, a cyclohexylpiperazine derivative, is a high affinity and selective sigma 2 (σ2) receptor agonist with a K_i of 0.68 nM. PB28 dihydrochloride is also a σ1 antagonist with a K_i 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.

(±)-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.

Phenyltoloxamine (Bistrimin) is an antihistamine agent with sedative and analgesic effects. Phenyltoloxamine also has potent Sigma-1 receptor binding affinity (K_i: 160 nM).
