CAS No. 1627929-55-8
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).

|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 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.
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.

* 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.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
