Application

DBF is dealkylated by cytochromes P450 (especially CYP2C8, CYP2C9, CYP2C19, and CYP3A) to form a fluorescein ester. Dibenzylfluorescein was reported to be suitable for in vitro assessment of the initial screening of CYP3A4-
mediated drug interactions. The fluorescent fluorescein product can be quantitated after the addition of base, which hydrolyzes the ester and increases the pH for optimal fluorescein fluorescence detection.

Other Notes

Dibenzylfluorescein is light sensitive and should be protected from direct sunlight or UV sources.

Mefentrifluconazole (trade name: Revysol®) is an agrochemical active ingredient from the new sub-class of isopropanol-triazole fungicides, with high selective fungicide activity. A full program of toxicity testing conducted according to OECD guidelines has shown mefentrifluconazole (MFZ) to be non-genotoxic and

Human activities can cause habitat degradation that may alter the types and quality of available food resources and thus influence the microbiomes of wild animal populations. Furthermore, seasonal shifts in food availability may cause adaptive responses in the gut microbiome

NADPH cytochrome P450 oxidoreductase (CPR) is the obligatory electron supplier that sustains the activity of microsomal cytochrome P450 (CYP) enzymes. The variant nature of the isoform-specific proximal interface of microsomal CYPs indicates that CPR is capable of multiple degenerated interactions

Ultrafiltration liquid chromatography with mass spectrometry can efficiently and rapidly screen and identify ligands from the seeds of Cicer arietinum for human aromatase. Using this method, we identified 11 major compounds, including organic acids, organic acid glycosides, flavone glycosides, isoflavones
