VS-II-173
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 .

VS-II-173 (1 μM) inhibits a range of protein kinases beyond Pim kinases, with potent activity against DYRK1A, HIPK2, PRK2, RSK1, and AMPKa1[1].
VS-II-173 (1 μM; 24 h) synergizes with Daunorubicin to induce cell death in Molm-13 AML cells, with additive effects with Etoposide (HY-13629), Emetine, Geldanamycin (HY-15230), and antagonism with high-concentration Bortezomib (HY-10227)[1].
VS-II-173 (3-12 μM; 1-6 h) modulates cell signaling in AML cell lines by downregulating Pim kinases and dephosphorylating Stat5, Bad, 4E-BP1, and MDM2[1].
VS-II-173 (EC50=3.7 μM，72 h) induces apoptosis in MOLM-13 acute myeloid leukemia cells[2].
VS-II-173 shows low cytotoxicity toward Normal Rat Kidney (NRK) epithelial cells (EC50 =>30 μM, 72 h)[2].
