Dojindo,SIN-1/25/S264,SIN-1 是血管扩张剂 molsidomine 的代谢物

SIN-1 是血管扩张剂 molsidomine 的代谢物,用于分别评估 NO 和过氧亚硝酸盐与其他 NO 供体的有效性。 SIN-1 在分子氧存在下自发分解生成 NO 和超氧化物。 两种产物都非常迅速地结合形成过氧亚硝酸盐(速率常数 k:3.7×10-7 M-1s-1)。 因此,SIN-1 是一种有用的化合物,可以有效地生成过氧亚硝酸盐。 过氧亚硝酸盐是一种非常强的氧化剂,在生理条件下会产生羟基和亚硝基二氧基自由基。 过氧亚硝酸盐也在酸性条件下快速分解生成硝酸根离子,在碱性条件下缓慢分解生成硝酸根离子。 这些物种具有与 NO 不同的生物活性。

细胞活力和细胞毒性测定用于药物筛选和化学物质的细胞毒性测试。Dojindo开发了高度水溶性的四唑盐,称为WST。WST-8是高度稳定的WST,用于Cell Counting Kit-8(CCK-8)。由于WST-8甲maz是水溶性的,因此不会形成晶体。因此,不需要诸如MTT测定的增溶过程。此外,CCK-8的检测灵敏度高于其他四唑盐,例如MTT,XTT,MTS或WST-1。
