Siramesine (Synonyms: Lu 28-179)

Siramesine (Lu 28-179) 是一种有效的 sigma-2 受体激动剂。Siramesine 对 sigma-2 受体具有亚纳摩尔亲和力 (IC50=0.12 nM)，并且对 sigma-2 受体的选择性是 sigma-1 受体的 140倍 (IC50=17 nM)。Siramesine 通过线粒体的不稳定而不是溶酶体触发细胞死亡。Siramesine 显示出强大的抗癌活性。

生物活性

Siramesine (Lu 28-179) is a potent sigma-2 receptor agonist. Siramesine 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 triggers cell death through destabilisation of mitochondria, but not lysosomes. Anti-cancer activity[1][2][3].

体外研究
(In Vitro)

Siramesine 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) 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) activates caspases in HaCaT and in U-87MG cells[2].
