5-Methyl-2-nitrobenzonitrile (cas: 64113-86-6) belongs to nitriles. Nitrile function is a very important functional group because it can be manipulated to other functional groups such as carboxylic acid by hydrolysis or amine by reduction, respectively. Some nitriles are manufactured by heating carboxylic acids with ammonia in the presence of catalysts. This process is used to make nitriles from natural fats and oils, the products being used as softening agents in synthetic rubbers, plastics, and textiles and for making amines.Formula: C8H6N2O2

Due to the biol. complexity of the N-methyl-D-aspartate receptor (NMDAR), the development of a positron emission tomog. radiotracer for the imaging of NMDAR has met with limited success. Recent studies have established the presence of GluN2A subunit of the NMDAR in the heart and its role in the regulation of intracellular calcium levels. In our efforts to develop an imaging agent for the GluN2A subunit, we designed three new compounds based on a quinoxaline scaffold. The synthesis of the analogs was based on a two-step Kabachnik-Fields reaction in sequence with Suzuki cross-coupling and acid hydrolysis. They exhibited comparable high binding affinity values below 5 nM. A two-step radiolabeling procedure was successfully developed for the synthesis of [18F]I. [18F]I was obtained in a modest overall radiochem. yield of 5.5 ± 4.2%, a good specific radioactivity of 254 ± 158 GBq/μmol, and a radiochem. purity > 99%. While two compounds showed comparable binding affinity towards NMDAR, sluggish radiolabeling, prevented their further evaluation. For [18F]I, in vitro autoradiog. on rat heart slices demonstrated heterogeneous but unspecific accumulation, whereas for the brain a high in vitro specificity towards NMDAR, could be demonstrated. In the experiment, the researchers used many compounds, for example, 5-Methyl-2-nitrobenzonitrile (cas: 64113-86-6Formula: C8H6N2O2).
