Figure 4From: CYP450 phenotyping and accurate mass identification of metabolites of the 8-aminoquinoline, anti-malarial drug primaquinePutative pathway to observed CYP 2D6 mediated phenolic and quinone metabolites. Positional isomers on the quinoline core have different observed retention times, but are isobaric; therefore individual peaks cannot be assigned for the six observed phenols.Back to article page
