    BI-D1870 purchased from MCE. Usage Cited in: Viruses. 2018 Apr 13;10(4). pii: E191.  [Abstract]

    H2.35 cells are serum starved for 72 h and then were pre-treated with either DMSO or BI-D1870 (p90 IN, 10 μM). Cells are infected with MP12 (MOI 5) for one hour, followed by removal of viral inoculum, and addition of growth medium containing DMSO or p90 IN (10 μM). At 18 hpi, cell lysates are collected for western blot analysis.

    H2.35 cells are serum starved for 72 h and then are pre-treated with either DMSO or 10 μM PD0325901 (ERK IN). Cells are infected with MP12 (MOI 5) for one hour, followed by removal of viral inoculum, and addition of growth medium containing DMSO or 10 μM ERK IN. At 18 hpi, cell lysates are collected for western blot analysis.

    BI-D1870 purchased from MCE. Usage Cited in: Oncotarget. 2016 Mar 1;7(9):10283-96.  [Abstract]

    HeLa cells synchronized at mitotic phase are treated with BI-D1870 at indicated concentrations. Phosphorylation of EBP50 is assayed by Western blotting using p-EBP50 (T156) antibody. Phosphorylation of RSK1 at S380 and ribosomal protein S6 (rpS6) at S235-236 are assayed to examine activation of RSK1 at mitotic phase. GAPDH or α-tubulin is examined as a loading control. The morphology of cells at the moment of harvest for the above experiment is shown in photographs.

    BI-D1870 抑制 PLK1,IC50 為 100 nM,而 Aurora B、DYRK1a、CDK2-A、Lck、CK1 的 IC50 值和 GSK3β 比 RSK 亞型高 10 到 100 倍。BI-D1870 (10 μM) 抑制 HEK-293 細(xì)胞中 PMA 誘導(dǎo)的 GSK3α 和 GSK3β 磷酸化。在 HEK-293 細(xì)胞中,BI-D1870 抑制 EGF 誘導(dǎo)的 LKB1 在 Ser431 位點的磷酸化,IC50 約為 1 μM[1]。
    BI-D1870 不影響 ERK1/ERK2 和 MSK1 的激活,也不抑制 CREB 的磷酸化[1]。
    BI-D1870 是一種有效的 RSK 家族激酶抑制劑 (Kds:10-100 nM),并且還與 BRD4 (1) 和 PLK 家族相互作用,其 K d 值分別為 3.5 μM 和大約 10 nM[2]
    BI-D1870 (10 μM) 在血清饑餓的 LN-229 細(xì)胞和 alao 中強(qiáng)烈誘導(dǎo) p70S6K 激活刺激 LN-18 細(xì)胞中 rpS6 和 p70S6K 的磷酸化。BI-D1870 (1 μM) 有效抑制 rpS6 磷酸化,并在濃度高于 1 μM[4]時抑制 PMA 誘導(dǎo)的 rpS6 磷酸化。

    Kinase Assay
    [1]

    Purified His6-RSK1, His6-RSK2 or GST-RSK21-389:S381E (1-2 units/mL) are assayed for 10 min at 30°C in a 50 μL assay mixture in Buffer A containing 30 μM substrate peptide (KEAKEKRQEQIAKRRRLSSLRASTSKSGGSQK), 10 mM magnesium acetate and 100 μM of [γ-32P]ATP. Reactions are terminated and analysed. The amount of enzyme that catalysed the phosphorylation of 1 nmol of substrate peptide in 1 min is termed one unit.

    Cell Assay
    [5]

    Measurement of cell growth is assessed using the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide] assay in six replicates. The cells (5×103/200 μL) are seeded in 96-well, flat-bottom plates for 24 h and then exposed to various concentrations of test agents for the indicated time intervals. After removing the culture medium, 200 μL of the medium containing MTT at a concentration of 0.5 mg/mL is added, and the cells are incubated at 37°C for 2 h. The medium is removed, and the reduced MTT dye in each well is dissolved in 200 μL DMSO. Absorbance is determined with a multimode microplate reader Synergy HT at 570 nm.

    Animal Administration
    [3]

    Myelin oligodendrocyte glycoprotein (MOG) peptide 35-55 MEVGWYRSPFSRVVHLYRNGK) (BEX) is used to induce EAE in C57/BL6J mice. Mice are injecteds.c. with 200 g of MOG peptide in 100 μL of PBS emulsified in 100 μL complete Freund’s adjuvant (CFA) that is further supplemented with five mg/mL Mycobacterium tuberculosis. In addition, 500 ng pertussis toxin is injected i.p. on days zero and two. The RSK inhibitor (BI-D1870; 0.5 mg/kg) is injected i.p. into mice two days after immunization with MOG peptide, and injection is repeated every other day for 11 days. Mice that receive only dimethyl sulfoxide (DMSO) solution are used as controls. Paralysis is evaluated according to the following scale: zero, no disease; one, tail limpness; two, hind limb weakness; three, hind limb paralysis; four, fore limb weakness; five, quadriplegia; six, death. For histological analysis, CNS samples are fixed with 4% paraformaldehyde and sliced at 4 μm, and then hematoxylin & eosin (H & E) staining is performed.

    • 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.
