Product Description

PF-4981517 (also named as PF 04981517; PF04981517, CYP-3cide, PF 4981517; PF4981517) is a specific and time-dependent inactivator of human CYP3A4 (P450) with IC50 of 0.03 μM, it exhibits >500-fold selectivity for inhibiting CYP3A4 over CYP3A5 and CYP3A7 and a time-dependent inactivation of human CYP3A4.

Biological Activity I Assay Protocols (From Reference)

ln Vitro

Using human liver microsomes from donors with nonfunctioning CYP3A5 (CYP3A5 *3/*3), an extraordinary metabolic inactivation efficiency (kinact/KI) of 3300 to 3800 ml • min-1 • μmol-1 is observed when examining the inhibitory characteristics of CYP3cide. This efficiency was found to correspond to an apparent KI of 420–480 nM and a maximal inactivation rate (kinact) of 1.6 min-1. The connection between CYP3A5 abundance and the remaining midazolam 1'-hydroxylase activity is strong when CYP3cide is assessed in a library of genotyped polymorphic CYP3A5 microsomes at a concentration and preincubation period that totally inhibits CYP3A4[1].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?

Enter 350.26 in the Molecular Weight (MW) box
Enter 10 in the Concentration box and choose the correct unit (mM)
Enter 5 in the Volume box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.
