InVivo Studies in Humans

Human drug metabolism studies have made extensive use of EI methodology (206,207). The uricosuric drug benzbromarone was found to be extensively metabolized in humans, forming two major metabolites (206). The metabolites were 1'-hydroxybenzbromarone and 6-hydroxybenzbromarone. Benzbromarone was hydroxylated in vivo at the prochiral center C1' to 1'-hydroxybenzbromarone. Analysis of 1'-hydroxybenzbromarone from plasma and urine extracts by chiral HPLC revealed that two peaks were eluted which...

Collisioninduced Dissociation

CID requires the tandem pairing of two mass analyzers tandem mass spectrometers . In this technique, an ion of one particular mass is allowed to pass through the first analyzer into a field-free region, where it collides with an inert gas to form product product ions. The product ions are then separated in the second analyzer, which in turn transmits them to the detector 4,35 . The type of instrumentation used in these studies can be a triple-stage quadrupole mass spectrometer, a four-sector...
