Neutral loss Experiment, Acetaminophen Turnover - Problem with turnover in acetaminophen by microsomes (Jul/22/2009 )

Having a problem seeing any turnover in Acetominophen in a neutral loss experiment.
Acetominophen incubuated with microsomes + 3 mixes

mix 1- GSH + MgCl2 +NADPH regenerating system
mix 2- GSH + MgCl2
mix 3- NADPH regenerating system

( no turnover is expected in mix 2)

Verapmil was also run with the same stock solutions and turnover was evident :D

What could be the cause of no to little turnover in Acetaminophen? ;)

Hi, possibly an irreversible inhibition with microsome binding?
