生物活性

VS-II-173 is a pan-Pim kinase inhibitor with IC50 values ​​of 0.07 μM and 0.02 μM for Pim1 and Pim3, respectively, and a residual activity of 46% for Pim2 at 1 μM. VS-II-173 also inhibits kinases such as HIPK2, PRK2, RSK1, DYRK1a and AMPKα1, selectively inhibiting acute myeloid leukemia (AML) cells with significantly lower toxicity to non-malignant cells (EC50 > 30 μM). VS-II-173 weakens the phosphorylation of substrates such as Stat5 (Y694), MDM2 (S166), Bad (S112), and 4E-BP1 (T37/46) by inhibiting Pim kinase-mediated signaling pathways, blocking pro-survival signals in AML cells and inducing apoptosis. VS-II-173 synergistically enhances anti-AML activity when combined with Daunorubicin (HY-13062A). VS-II-173 can be used in AML research, especially for AML with FLT3-ITD mutations and NPM1 mutations [1][2].

体外研究
(In Vitro)

VS-II-173 (1 μM) 可抑制 Pim 激酶以外的多种蛋白激酶,对 DYRK1A、HIPK2、PRK2、RSK1 和 AMPKa1 具有强效活性 [1]
VS-II-173 (1 μM;24 h) 与 Daunorubicin 协同诱导 Molm-13 AML 细胞死亡,与 Etoposide (HY-13629),Emetine,Geldanamycin (HY-15230) 具有叠加效应,而与高浓度 Bortezomib (HY-10227) 存在拮抗作用 [1]
VS-II-173 (3-12 μM;1-6 h) 可通过下调 Pim 激酶并使 Stat5、Bad、4E-BP1 和 MDM2 去磷酸化,从而调控 AML 细胞系中的细胞信号传导 [1]
VS-II-173 (EC50=3.7 μM,72 h) 可诱导 MOLM-13 急性髓系白血病细胞凋亡[2]
VS-II-173 对正常大鼠肾 (NRK) 上皮细胞的细胞毒性较低 (EC50=>30 μM,72 h) [2]

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.
