Characterizing Metabolic Inhibition Using Electrochemical Enzyme/DNA Biosensors [PDF]

open access: yesAnalytical Chemistry, 2008
Studies of metabolic enzyme inhibition are necessary in drug development and toxicity investigations as potential tools to limit or prevent appearance of deleterious metabolites formed, for example, by cytochrome (cyt) P450 enzymes. In this paper, we evaluate the use of enzyme/DNA toxicity biosensors as tools to investigate enzyme inhibition.
