BRD9876 is the “rigor” inhibitor that locks kinesin-5 (Eg5) in a state with enhanced microtubules (MTs) binding, leading to bundling and stabilization of MTs. BRD9876 interacts with the tyrosine 104 residue that is part of the α4-α6 allosteric binding pocket. BRD9876 specifically targets microtubule-bound Eg5 and selectively inhibits myeloma over CD34 cells. BRD9876 has the potential for multiple myeloma (MM) research.

Description

BRD9876 is the “rigor” inhibitor that locks kinesin-5 (Eg5) in a state with enhanced microtubules (MTs) binding, leading to bundling and stabilization of MTs. BRD9876 interacts with the tyrosine 104 residue that is part of the α4-α6 allosteric binding pocket. BRD9876 specifically targets microtubule-bound Eg5 and selectively inhibits myeloma over CD34 cells. BRD9876 has the potential for multiple myeloma (MM) research[1][2][3][4].

In Vitro

BRD9876 (10 μM; 24 hours) reveales rapid arrest of cells at the G2/M phase starting as early as 2h of treatment in MM1S cells[1].
BRD9876 exhibits approximately 3-fold selectivity for MM1S myeloma cells (IC50=3.1 μM) over CD34+ derived hematopoietic cells (IC50=9.1 μM)[1].
BRD9876 (0.1, 1, 10, 100 uM) is able to overcome, in MM1S cells, stromal resistance of bone marrow stromal cells (BMSCs) from MM bone marrow aspirates but only minimal effects are observed with BRD9876 against primary MM cells[1].
BRD9876 is completely ineffective at inhibiting the basal ATPase activity of Eg5, in contrast to loop L5-binding monastrol or α4/α6-binding BI8 which shows greater activity against basal Eg5 ATPase activity[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 (10.67 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.

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.
