Introduction of 878141-96-9 :

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]. In Vitro:S1RA (E-52862; 100 µM; 4 h) inhibit intracellular calcium responses in TRPA1 expressing HEK293 cells[2].
S1RA (100 µM; 4 h) impairs the formation of TRPA1–Sigma-1R complexes and reduces TRPA1 expression at the plasma membrane[2].
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].
