生物活性

MT-44 is a highly selective and potent mTOR inhibitor with an IC50 of 49.4 nM. MT-44 can inhibit cancer cells proliferation, migration and invasion. MT-44 can induce cells apoptosis and ROS production and cause G2/M phase arrest. MT-44 can activate the cGAS/STING pathway. MT-44 can be used for the research of cancer, such as triple-negative breast cancer[1].

体外研究
(In Vitro)

MT-44 对 TNBC 细胞 MDA-MB-231 和 MDA-MB-468 具有强效抗增殖活性,IC50 分别为 66.5 nM 和 148.2 nM[1]
MT-44 (0.25-1.0 μM, 12-48 h) 浓度依赖性抑制 MDA-MB-231 细胞迁移,并诱导细胞 G2/M 期阻滞[1]
MT-44 (0.05-0.5 μM) 显著抑制 MDA-MB-231 细胞集落形成和侵袭[1]
MT-44 (0.5-2.0 μM, 24 h) 浓度依赖性诱导 MDA-MB-231 细胞凋亡,促进细胞自噬并增加 ROS 积累[1]
MT-44 (0.5-2.0 μM, 24 h) 下调 MDA-MB-231 细胞中 p-P70S6K、p-Akt、p-4EBP1 的磷酸化水平,并上调 cGAS/STING 通路磷酸化蛋白[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
