C16H13ClF3NO2
Molecular Weight 343.73 CAS No. 451491-47-7
Solubility (25°C)* In vitro DMSO 69 mg/mL (200.73 mM)
Ethanol 17 mg/mL (49.45 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 70 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% Corn oil
3.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 70 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. 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 CTB is a p300 activator and the lowest docked energy for CTB and p300 is 7.72 kcal/mol.
In vitro

CTB effectively induces apoptosis, up-regulates the expression of P300, and increases the acetylation and total P53 protein levels in MCF-7 cells.[2]
In vivo

CTB combinated with CpG, and aluminum hydroxide playsa synergistic effect to enhance ClfA221-550-induced immune responses, which possesses the potential to develop a novel vaccine to prevent infection of S. aureus.[3]

Protocol (from reference)

Cell Assay:

[2]
  • Cell lines

    MCF-7 and MRC-5 cells

  • Concentrations

    85.43 µM

  • Incubation Time

    24, 48, 72 h

  • Method

    MCF-7 and MRC-5 are cultured in RPMI-1640 and treated with or without CTB at a concentration of 85.43 μmol/L at different times (24, 48 and 72 h). The percentage of apoptotic cells are measured by flow cytometry.Real-time quantitative RT-PCR is performed to estimate the mRNA expression of P300 in MCF-7 and MRC-5 with CTB at different times. ELISA and Bradford protein techniques are used to detect levels of total and acetylated P53 protein generated in MCF-7 and MRC-5.
Animal Study:

[3]
  • Animal Models

    Specific-pathogen-free BALB/c mice

  • Dosages

    100 μg

  • Administration

    i.m.
