S1RA Chemical Properties,Usage,Production
Uses
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[1][2].
Biological Activity
s1ra is a potent and selective antagonist of σ1 receptor (σ1r) with ki value of 17nm [1].s1ra is the first σ1 receptor antagonist with potent antinociceptive activities in various pain models. in the binding assay, s1ra shows good affinity to human σ1 receptor transfected in hek293 membranes with ki value of 17nm. the ki value for guinea pig brain membrane σ1 receptor is higher than 1μm. s1ra also shows no significant affinity to another 170 molecular targets including receptors, ion channels and enzymes [1, 2].in the mouse tests, s1ra exhibits potent analgesic effects on capsaicin-induced mechanical hypersensitivity and formalin-induced pain. besides that, s1ra inhibits both mechanical allodynia and thermal hypersensitivity with ed50 values of 23.4mg/kg and 18.8mg/kg in the partial sciatic nerve ligation model in mice [1].
in vivo
S1RA (E-52862; 40 mg/kg; IP; single dose) produces a substantial reduction in pain-related responses to intradermal Allylisothiocyanate (AITC) in WT mice[2].
S1RA (40 mg/kg; IP; once a day for 11 consecutive days; starting 3 days before Oxaliplatin injection) prevents mechanical and cold hypersensitivity in Oxaliplatin (6 mg/kg; i.p.; Day 0, Day 2, Day 4)-treated mice[2].
| Animal Model: | WT and TRPA1 KO mice with AITC (10 μl at 10 mM) in their hind paws[2] |
| Dosage: | 40 mg/kg |
| Administration: | IP; single dose; 24-h before evaluation |
| Result: | Produced a substantial reduction in pain-related responses to intradermal AITC in WT mice. |
IC 50
human σ1R: 17 nM (Ki); guinea pig σ1R: 23.5 nM (Ki); guinea pig σ2R: >1000 nM (Ki); rat σ2R: 9300 nM (Ki); human 5-HT2B Receptor: 328 nM (Ki)
