A noncarcinogenic and structural analogue of polycyclic aromatic hydrocarbon (PAH), phenanthrene labeled with deuterium ([D10]Phe) with potential use in assessing an individuals capacity for PAH metabolism by the diol epoxide pathway. Upon oral or inhalation administration, [D10]Phe is metabolized into the tetraol end product ([D10]PheT) via the diol epoxide pathway, and can be quantified in urine. [D10]PheT can be used as a biomarker to assess PAHs metabolic activation and may therefore determine an individuals susceptibility to carcinogenicity upon PAH exposure. Check for active clinical trials using this agent. (NCI Thesaurus)
