| Bioactivity | ST-401, a microtubule-targeting agent (MTA), is a brain-penetrant microtubule (MT) assembly inhibitor. ST-401 disrupts microtubule (MT) function through gentle and reverisible reduction in MT assembly that triggers mitotic delay and cell death in interphase. ST-401 shows a potent antitumor activity[1]. |
| Invitro | ST-401 是一种混合分子，将仲醇和喹啉结合在一个结构中。ST-401 竞争 89% 的 [3H]秋水仙碱与微管蛋白的结合。在浊度测定中，ST-401 抑制微管蛋白组装，IC50 为 1.1 µM。在测量游离微管蛋白释放的沉淀测定中，ST-401 抑制微管蛋白组装，IC50 值为 3.2 µM[1]。 ST-401 在大多数人类癌细胞系中表现出类似的低纳摩尔抗肿瘤活性，包括六种神经胶质瘤系（SF-268、SF-295、SF-539、SNB-19、SNB-75 和 U251：IC50 为 23-69 nM）[1]。ST-401 在 PD-神经胶质瘤中表现出低纳摩尔抗肿瘤活性（IC50：24-47 nM）[1]。ST-401（72 小时）降低了 MGG8 和 T98G 细胞中的整体细胞活力，IC50 相当（分别为 14 和 36 nM）[1]。 MCE has not independently confirmed the accuracy of these methods.
