The present disclosure relates to an in vivo fluorescent or radioactive probe represented by a compound of formula I which is capable of longitudinal imaging of inducible nitric oxide synthase (iNOS) expression in living cells and living animals on a real time basis. The probe of the present disclosure can exhibit specific and high affinity binding to the iNOS enzyme with reduced enzyme inhibitory property and also enables longitudinal monitoring of iNOS expression along with its activity or NO production in a same experimental subject throughout the progression of a physiological or disease process without employing separate subjects as controls and experimental. The present disclosure further provides a rapid and inexpensive real time method for visualizing iNOS expression and its activity in living cells and living animals precisely, conveniently and reversibly along with simultaneous in vivo imaging of its catalytic product, nitric oxide (NO) in live physiological settings.
