The present invention relates to novel quinolones of Formula I that inhibit inducible NOS synthase together with methods of synthesizing and using the compounds including methods for inhibiting or modulating nitric oxide synthesis and/or lowering nitric oxide levels in a patient by administering the compounds for the treatment of disease.
Under catalyst-free conditions, an efficient method to synthesize 2-pyridinylamides has been developed, and the protocol uses inexpensive and readily available 2-fluoropyridine and amidine derivatives as the starting materials. Simultaneously, the copper-catalysed approach to imidazopyridine derivatives has been established with high chemoselectivity and regiospecificity. The results suggest that the

The present invention is directed to substituted cyclopropyl imidazopyridine compounds which are useful as therapeutic agents for the treatment of central nervous system disorders associated with phosphodiesterase 10 (PDE10). The present invention also relates to the use of such compounds for treating neurological and psychiatric disorders, such as schizophrenia, psychosis or Huntington's disease, and those associated with striatal hypofunction or basal ganglia dysfunction.

improved copper-catalyzed cyclization for an efficient synthesis of benzimidazoles from o-bromoarylamine and nitriles, under mild and ligand-free conditions. The optimal conditions yielded exceptional products of up to 98%, demonstrating the broad applicability of this synthetic strategy in generating a wide range of valuable imidazole derivatives. This methodology enables the efficient synthesis of various
