|Description||PFI-3 is a selective chemical probe for SMARCA bromodomains, including SMARCA2, SMARCA4 and PB1(5) bromodomains.|
PFI-3 shows a significant selectivity for PB1(5) and SMARCA2/4 over 36 other tested kinases. PFI-3 is a potent and cell active protein interaction inhibitor that selectively binds to essential BAF bromodomains. PFI-3 is screened in a commercial screening panel comprising 102 cellular receptors as well as 30 enzyme assays, revealing only interactions against four GPCRs with micromolar affinity and no significant additional interactions outside the BRD family, confirming its excellent broader pharmacological selectivity. Stability measurements confirmed that PFI-3 has a half-life in aqueous solutions exceeding 7 days at 37°C. In long-term experiments, PFI-3 significantly altered gene expression programs that are important for differentiation of stem cells. PFI-3 mimics the effect of Brg1 deletion, resulting in an increase of the repressive H3K27me3 mark at the TSSs and Stat3 binding sites of these genes. PFI-3 has a half-life of >250 h in PBS, pH 7.4, at 20 °C.

* 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.
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 MSDS / 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 MSDS / 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.
