Enzyme inhibitor

This substituted pyridine (FW = 155.20 g/mol; CAS 939-23-1; M.P. = 69- 73°C; B.P. = 274-275°C), which occurs naturally and is likewise a manmade pollutant, inhibits human placental aromatase, Ki = 0.36 μM, monoamine oxidase, and NADH dehydrogenase. 4-Phenylpyridine is also an effective inhibitor of mitochondrial complex I. Note that it both occurs naturally and is an environmental pollutant.
