Clear solution
5% DMSO 95% Corn oil
0.55mg/ml Taking the 1 mL working solution as an example, add 50 μL of 11 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. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
4.4mg/ml Taking the 1 mL working solution as an example, add 50 μL of 88 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. 
* <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 PLX51107 is as a novel BET inhibitor with modest preference for bromodomain-1 (BD1) versus bromodomain-2 (BD2) within each BET protein (Kd = 1.6, 2.1, 1.7, and 5 nM for BD1 and 5.9, 6.2, 6.1 and 120 nM for BD2 of BRD2, BRD3, BRD4, and BRDT, respectively. Among non-BET proteins, PLX51107 shows significant interactions only with the bromodomains of CBP and EP300 (p300) (Kd in the 100 nM range).

In vitro

In a set of cell cultures, short-term (4h) treatment of PLX51107 result in robust change in PD markers but do not induce an immediate apoptotic response. Induction of apoptosis occurrs after prolonged treatment (16 hours or more of continuous exposure). PLX51107 induces accumulation of p21 and IκBα, reduced levels of cMYC, and modulation of pro- and anti-apoptotic proteins[1].
In vivo

PLX51107 is well tolerated in mice. The half-life of PLX51107 is relative short in rodents and dogs (<3 h). PLX51107 demonstrates in vivo antitumor effects in preclinical models of CLL and aggressive lymphoma[1].
