1.25mg/ml Taking the 1 mL working solution as an example, add 50 μL 25 mg/ml clarified DMSO stock solution to 400 μL PEG300, mix evenly to clarify it; add 50 μL Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description SR-4835 is a highly selective dual inhibitor of CDK12 and CDK13 with IC50 of 99 nM and Kd of 98 nM for CDK12 and IC50 of 4.9 nM for CDK13. SR-4835 disables triple-negative breast cancer (TNBC) cells. SR-4835 promotes synergy with DNA-damaging chemotherapy and PARP inhibitors.

(Cell-free assay)
4.9 nM 98 nM(Kd) 99 nM
In vitro

SR-4835 is a selective, potent dual inhibitor of CDK12 and CDK13, suppressing expression of DDR proteins. CDK12/CDK13 inhibition synergizes with DNA-damaging agents or PARP inhibition to trigger TNBC cell death.[1]
In vivo

SR-4835 has potent in vivo anti-TNBC activity and augments the anti-cancer activity. SR-4835 is well tolerated in mice after long-term dosing. SR-4835 cooperates with DNA-damaging chemotherapeutics.[1]

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    Human: MDA-MB-231, MDA-MB-436, HS578T, MDA-MB-468, FHC

  • Concentrations

    10-90 nM, 0.4-10 μM

  • Incubation Time

    4 h, 6 h, 72 h

  • Method

    Clonogenic Assays. 500 cells per well are plated in six-well dishes in triplicate. After overnight incubation, SR-4835 is added to the medium for 72 hr, and cells are allowed to grow for 7 to 10 days, during which medium is changed every 2 to 3 days.
Animal Study:

[1]
  • Animal Models

    Female SCID Beige mice bearing xenograft tumor fragments, male C57Bl-6 mice

  • Dosages

    20 mg/kg

  • Administration

    Oral gavage, IV
