Product Description

BAY-61-3606 (BAY 61-3606, BAY 61-3606), cell-permeable imidazopyrimidine compound, is a potent and selective, oral, ATP-competitive, reversible inhibitor of Syk (Spleen tyrosine kinase) tyrosine kinase with Ki of 7.5 nM. It shows no inhibitory effect on Btk, Fyn, Itk, Lyn, and Src kinases. It has been demonstrated that BAY 61-3606 inhibits Syk-mediated cellular functions, including the inhibition of high glucose-tyrosine phosphorylation of I kappa B α and nuclear translocation of p65. BAY 61-3606 has inhibited degranulation, lipid mediation, and cytokine synthesis in mast cells. Moreover, BAY 61-3606 inhibited the activation of monocytes and eosinophils by B cells and Fc receptors.

Biological Activity I Assay Protocols (From Reference)
Targets
Syk (Ki = 7.5 nM); Syk (IC50 = 10 nM)
ln Vitro

BAY 61-3606 is a highly selective inhibitor of Syk kinase. BAY 61-3606 does not inhibit Lyn, Fyn, Src, Itk, and Btk, or any other selected tyrosine kinases, at concentrations as high as 4.7 μM. It has also been discovered that BAY 61-3606 inhibits B cell receptor (BCR)-mediated signaling[1].
Bay 61-3606 is an apoptosis sensitizer induced by TRAIL. In MCF-7 cells, Mcl-1 downregulation by Bay 61-3606 is concentration- and time-dependent. Bay 61-3606 decreases Syk phosphorylation in MCF-7 and T47D cells. In breast cancer cells, Bay 61-3606 downregulates Mcl-1 without the help of Syk. In MCF-7 cells, Bay 61-3606 facilitates the ubiquitin/proteasome-dependent degradation of the Mcl-1 protein. In MCF-7 cells, Bay 61-3606 suppresses the phosphorylation of CDK9, RNA polymerase II, and Mcl-1 expression. CDK9 kinase activity is inhibited by Bay 61-3606, with an in vitro IC50 of 37 nM[2].

ln Vivo
The efficacy of Bay 61–3606 in combination with TRAIL was significantly (P <0.001) reduced in the volume of the xenografted tumor after 20 days of drug administration[2].
At 3 mg/kg, oral BAY 61-3606 administration to rats significantly reduces bronchoconstriction, bronchial edema, and antigen-induced passive cutaneous anaphylactic reaction. Moreover, rats' airway inflammation brought on by antigens is reduced by BAY 61-3606[1].
Enzyme Assay
In mast cells, BAY 61-3606 inhibited lipid mediator and cytokine synthesis in addition to degranulation (IC50 values ranging from 5 to 46 nM). In basophils taken from healthy human subjects, BAY 61-3606 was very effective (IC50 = 10 nM), and it appears to be at least as potent (IC50 = 8.1 nM) in basophils taken from atopic (high serum IgE) subjects. BAY 61-3606 was also found to potently suppress B cell receptor activation as well as receptors for the Fc portion of IgG signaling in eosinophils and monocytes. In colorectal cancer cells expressing mutant forms of K-RAS, but not in isogenic cells expressing wild-type K-RAS, we found that BAY61-3606 inhibits the proliferation of these cells. Beyond its ability to inhibit cell division in mutant models, BAY61-3606 demonstrated a unique biological characteristic in wild-type cells: it bestowed susceptibility to RAF inhibition. In this instance, BAY61-3606 worked by blocking MAP4K2 (GCK), which in wild-type cells typically triggers NFκβ signaling in reaction to RAF inhibition.
Cell Assay
After a 24-hour period, MCF-7 cells are exposed to TRAIL (specified concentrations: 0, 12.5, 25, and 37.5 ng/ml) with or without Bay 61-3606 (2.5 μM). Following this exposure, the cells undergo immunocytochemistry using an active Bak antibody. MCF-7 cells exposed to Bay 61-3606 (5 μM) with or without TRAIL (50 ng/ml) for a 24-hour period are tested for caspase activity.
Animal Protocol
Female BALB/c nude mice (5 weeks old) bearing MCF-7 tumor xenograft
50 mg/kg
TRAIL (10 mg/kg), Bay 61-3606 (50 mg/kg), or a combination of both (50 mg/kg) was intraperitoneally injected twice a week; TRAIL was administered two hours following the injection of Bay 61-3606 for a duration of two weeks.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
