Introduction of 224177-60-0 :

Siramesine (Lu 28-179) hydrochloride is a potent sigma-2 receptor agonist. Siramesine hydrochloride has a subnanomolar affinity for sigma-2 receptors (IC50=0.12?nM) and exhibits a 140-fold selectivity for sigma-2 receptors over sigma-1 receptors (IC50=17?nM). Siramesine hydrochloride triggers cell death through destabilisation of mitochondria, but not lysosomes. Anti-cancer activity[1][2][3]. In Vitro: Siramesine hydrochloride displays the binding affinities: IC50 (sigma 1)=17 nM, IC50 (sigma 2)=0.12 nM, IC50 (5-HT1A)=21000 nM, IC50 (5-HT1A)=2000 nM, IC50 (D2)=800 nM, IC50 (alpha 1)=330 nM[1].
Siramesine (0-50μM; 8 hours) hydrochloride induces cell death in various cell lines (HaCaT, Hsc-4, HeLa and MCF-7, neuroblastoma cell line SH-SY5Y and glioblastoma cell line U-87MG)[2].
Siramesine (0-40 μM; 2-48 hours) hydrochloride activates caspases in HaCaT and in U-87MG cells[2].
