Radiolabeled 2-amino-4-alkyl-6-(haloalkyl)pyridine compounds are disclosed. In some aspects, the compounds bind to inducible nitric oxide synthase (iNOS) with high specificity. In some configurations, a compound comprising a radioisotope can be used for diagnostic imaging of iNOS distribution in a mammalian subject such as a human, using a scanning method such as positron emission tomography (PET scanning). Methods of synthesis of the compounds are also disclosed.
Design and Synthesis of 2-Amino-4-methylpyridine Analogues as Inhibitors for Inducible Nitric Oxide Synthase and in Vivo Evaluation of [<sup>18</sup>F]6-(2-Fluoropropyl)-4-methyl-pyridin-2-amine as a Potential PET Tracer for Inducible Nitric Oxide Synthase

A series of position-6 substituted 2-amino-4-methylpyridine analogues was synthesized and compounds 9, 18, and 20 were identified as the inhibitors with the greatest potential to serve as PET tracers for imaging inducible nitricoxidesynthase (iNOS). [18F]9 was synthesized and evaluated in a mouse model of lipopolysaccharide (LPS)-induced iNOS activation. In vivo biodistribution studies of [18F]9
