Solubility (25°C)* In vitro DMSO 6 mg/mL (12.95 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
0.3mg/ml Taking the 1 mL working solution as an example, add 50 μL 6 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 BAY-61-3606 is a potent and selective inhibitor of Syk kinase (Ki = 7.5 nM). BAY-61-3606 induces cell cycle arrest and apoptosis.
Targets
Syk [1]
(Cell-free assay)
7.5 nM(Ki)
In vitro

BAY 61-3606 is a highly selective inhibitor of Syk kinase. Other selected tyrosine kinases, Lyn, Fyn, Src, Itk, and Btk, are not inhibited by BAY 61-3606 in concentrations up to 4.7 μM. BAY 61-3606 is also found to inhibit B cell receptor (BCR)-mediated signaling[1].

Bay 61-3606 is a sensitizer of TRAIL-induced apoptosis. Mcl-1 downregulation by Bay 61-3606 are concentration- and time-dependent in MCF-7 cells. phosphorylation of Syk is reduced by Bay 61-3606 in MCF-7 and T47D cells. Downregulation of Mcl-1 by Bay 61-3606 is independent of Syk in breast cancer cells. Bay 61-3606 promotes the ubiquitin/proteasome-dependent degradation of the Mcl-1 protein in MCF-7 cells. Bay 61-3606 inhibits the phosphorylation of CDK9, RNA polymerase II, and Mcl-1 expression in MCF-7 cells. Bay 61-3606 inhibits CDK9 kinase activity with an in vitro IC50 of 37 nM[2].
In vivo

After 20 days of drug administration, the volume of the xenografted tumor was significantly (P <0.001) reduced the efficacy of Bay 61–3606 when administered in TRAIL combination[2].

Oral administration of BAY 61-3606 to rats significantly suppresses antigen-induced passive cutaneous anaphylactic reaction, bronchoconstriction, and bronchial edema at 3 mg/kg. Furthermore, BAY 61-3606 attenuates antigen-induced airway inflammation in rats[1].

Protocol (from reference)

Cell Assay:

[2]
  • Cell lines

    MCF-7 cells

  • Concentrations

    2.5 μM or 5 μM

  • Incubation Time

    12 h or 24 h

  • Method

    MCF-7 cells are exposed to TRAIL (indicated concentrations:0, 12.5, 25, 37.5 ng/ml) with or without Bay 61-3606 (2.5 μM) for 24 h; After exposure to the agents for 12 h, MCF-7 cells are subjected to immunocytochemistry using an active Bak antibody; Caspase activity is measured in MCF-7 cells exposed to Bay 61-3606 (5 μM) with or without TRAIL (50 ng/ml) for 24 h.
