A familiar probe substrate does not guarantee identical enzyme contributions in different species.
What the supplied source reports
The laboratory survey examined twenty-eight probe oxidation reactions in marmoset liver and intestinal microsomes. Midazolam hydroxylation activities correlated with some other oxidation measures, and liver and intestinal activities were roughly comparable for selected substrates. The investigators considered implications for preclinical modeling.
Limits and uncertainty
Microsomal activity is not whole-animal clearance, and similarity in substrate recognition does not establish identical enzyme identity or regulation. Correlated reactions can reflect shared contributors without proving a single isoenzyme mechanism. The experiment did not measure human benzodiazepine effects.
Implications for forensic review
When interpreting animal pharmacokinetics, specify the species, tissue preparation and metabolic pathway tested. Avoid transferring human CYP selectivity automatically to a nonhuman primate assay. The paper supports informed model selection while leaving patient-specific exposure and clinical interaction magnitude unresolved.
