SA-4503 (165377-44-6)

SA4503 2Hcl(AGY-94806 2Hcl; Cutamesine 2Hcl) is a selective sigma 1 receptor(σ1R) agonist; high affinity for the sigma 1 receptor subtype labeled by (+)-[3H]pentazocine (IC50 = 17.4 +/- 1.9 nM); 100-fold less affinity for the sigma 2 receptor.

Not Intended for Therapeutic Use. For research use only.

SA-4503 (165377-44-6) Description:

 Cutamesine, also known as SA-4503 and AGY94806, is a sigma-1 receptor agonist under development for recovery enhancement after acute ischemic stroke. Cutamesine protects against retinal cell death in vitro and in vivo by the agonistic effect of sigma-1 receptor. Therefore, sigma-1 receptor may have a potential as a therapeutic target in retinal diseases mediated by photoreceptor degeneration. .
