|Description||PF-4981517 is a potent and selective inhibitor of CYP3A4 (P450) with IC50 of 0.03 μM, exhibits >500-fold selectivity over CYP3A5 and CYP3A7.|
PF-4981517 (CYP3cide) is a potent, efficient, and specific time-dependent inactivator of human CYP3A4. PF-4981517 is tested as a reversible inhibitor of several human cytochrome P450 activities in pooled HLMs. PF-4981517 is selective for CYP3A4 with IC50 of 0.03 μM, 17 μM and 70 μM for CYP3A4, 3A5, and 3A7, respectively. PF-4981517 is a mechanism-based inactivator. PF-4981517 serves as an important in vitro tool, which when used side-by-side with ketoconazole to inhibit all CYP3A activity will permit distinction between the contribution of CYP3A4 to CYP3A5 (as well as CYP3A7 and maybe CYP3A43). PF-4981517 is useful to investigators seeking to delineate the relative contribution of CYP3A4 versus CYP3A5 in the metabolism of compounds cleared by CYP3A.

* 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.
