WhichCyp: prediction of cytochromes P450 inhibition
SUMMARY In this work we present WhichCyp, a tool for prediction of which cytochromes P450 isoforms (among 1A2, 2C9, 2C19, 2D6 and 3A4) a given molecule is likely to inhibit. The models are built from experimental high-throughput data using support vector machines and molecular signatures. AVAILABILITY The WhichCyp server is freely available for use on the web at http://drug.ku.dk/whichcyp, wh...
متن کاملHuman cytochromes P450 in health and disease.
There are 18 mammalian cytochrome P450 (CYP) families, which encode 57 genes in the human genome. CYP2, CYP3 and CYP4 families contain far more genes than the other 15 families; these three families are also the ones that are dramatically larger in rodent genomes. Most (if not all) genes in the CYP1, CYP2, CYP3 and CYP4 families encode enzymes involved in eicosanoid metabolism and are inducible...
متن کاملCytochromes P450 in the bioactivation of chemicals.
The initial view that the cytochrome P450 enzyme system functions simply in the deactivation of xenobiotics is anachronistic on the face of mounting evidence that this system can also transform many innocuous chemicals to toxic products. However, not all xenobiotic-metabolising cytochrome P450 subfamilies show the same propensity in the bioactivation of chemicals. For example, the CYP2C, 2B and...
متن کاملMetabolism of melatonin by human cytochromes p450.
In humans, the pineal hormone melatonin (MEL) is principally metabolized to 6-hydroxymelatonin (6-HMEL), which is further conjugated with sulfate and excreted in urine. MEL O-demethylation represents a minor reaction. The exact role of individual human cytochromes P450 (P450s) in these pathways has not been established. We used a panel of 11 recombinant human P450 isozymes to investigate for th...
متن کاملNature's universal oxygenases: the cytochromes P450.
Cytochromes P450 are utilized in an enormous diversity of biological reactions, including degradation of xenobiotics, generation of hormones and biosynthesis of a variety of important biological compounds. The cytochrome P450 family is a major participant in nearly all metabolism of pharmaceutical reagents. The presence of different P450 enzymes in various quantities in individuals makes the pr...
