Vivid® CYP450 Screening Kits rapidly screen compounds early in the drug discovery process for Cytochrome P450-drug interactions and to generate data for predictive structure-activity relationship (SAR) modeling. Vivid® CYP450 Screening Kits provide the high performance, throughput and reliability you need to speed selection of novel compounds for drug development.
The Vivid® P450 Metabolism assays are:
Vivid® Substrates are blocked dyes that yield minimal fluorescence until oxidative cleavage occurs (Figure 1A). Metabolism at either of two potential cleavage sites releases the highly fluorescent product. P450 inhibitors are identified by their ability to prevent the production of the fluorescent metabolite. The three-step Vivid® screening assay (Figure 1B) is a simple mix-and-read protocol that does not require stop reagents to conduct the reaction in kinetic mode.
Vivid® Kits and Substrates are available for a variety of P450 isozymes (Table 1). Each kit includes the isozyme-specific P450 BACULOSOMES® Plus Reagent, a Vivid® Substrate, and an NADPH regeneration system. The excitation and emission wavelengths of cleaved Vivid® Substrates are in the visible region and are subject to little or no fluorescent interference from NADPH or most test compounds.
P450 activity can be inhibited by solvents commonly used to dissolve test compounds. The following sample data (Table 2) is intended as a guide for the selection and use of organic solvents. We always recommend including a solvent control in your experimental design.
