Description

2OH-BNPP1 is an inhibitor of BUB1 kinase, a Ser/Thr kinase, used for the treatment of cancer.

IC50 & Target

BUB1 kinase[1]
In Vitro

2OH-BNPP1 (0.1-50 μM) abrogates TGFβ signaling in a dose dependent manner. 2OH-BNPP1 dose-dependently impairs the TGFβ-induced phosphorylation of proteins that mediate canonical and non-canonical TGFβ signaling in multiple cancer cell lines and normal cell lines[1].

2OH-BNPP1 Related Antibodies
In Vivo

2OH-BNPP1 (50 mg/kg) blocks TGFβ signaling in vivo, and significantly decreases abundance of phosphorylated SMAD2 in tumor-bearing mice[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (8.41 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  50% PEG300    50% Saline

    Solubility: 10 mg/mL (33.63 mM); Suspended solution; Need ultrasonic

Kinase Assay
[1]

In vitro kinase assays are performed using 200 ng of protein (BUB1-WT, or a kinase inactive mutant BUB1-KD), and 2 µg of substrate (TGFBRI-WT, TGFBRI-KD, SMAD3 or H2A) in 1X kinase buffer (50 mM Tris-HCl, 150 mM NaCl, 10 mM MgCl2, 1% (v/v) Glycerol, 0.1% (v/v) Triton X 100, DTT, PMSF, Na3VO4 (1 mM each), 2 mM NaF and β-glycerol phosphate) in 20 µL volume containing 10 µCi 32p-ATP and 300 µM cold ATP. Reactions are run at 30ºC for 0.5-1 hour and quenched using Laemmli buffer and resolved using a 4-12% Bis-Tris gel. Quantitative autoradiography is performed using a Typhoon FLA 9000 scanner.

Animal Administration
[1]

Cell line-derived xenografts are established by implanting 2.5×106 A549 cells subcutaneously into each flank of 4-6 week old male SCID mice. When tumors reach a volume between 40 to 60 mm3, mice are injected with a single intraperetoneal dose of SB431542 (10 mg/kg body weight), a dose previously reported to inhibit TGFβ signaling in mouse models, or 2OH-BNPP1 (50 mg/kg), or vehicle (DMSO). Tumors are excised 4 hours after treatment and fixed in formalin. Paraffin-embedded sections are stained using an antibody for phosphorylated SMAD2, and micrographs are taken with an Olympus microscope fitted with an Olympus DP-70 high resolution digital camera. The proportion of nuclei that stains positive for phosphorylated SMAD2 are counted in three random fields per tumor per treatment condition [vehicle (n=4), SB431542 (n=2), and 2OH-BNPP1 (n=5)]. A two -ided Student's t-test is performed to assess statistical significance. Slides are adjusted for brightness and contrast with Adobe Photoshop CS2, but the micrographs undergo no further manipulations.

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.
