Synthesis and Pharmacological Evaluation of 3-[(4-Oxo-4<i>H</i>-pyrido[3,2-<i>e</i>][1,3]thiazin-2-yl)(phenyl)amino]propanenitrile Derivatives as Orally Active AMPA Receptor Antagonists
cultures. Here, we synthesized 10 analogs bearing a 2-cyanoethyl group and administered them to mice to evaluate their anticonvulsant activity in maximal electroshock (MES)- and pentylenetetrazol (PTZ)-induced seizure tests, and their effects on motor coordination in a rotarod test. 3-(4-Oxo-4H-pyrido[3,2-e][1,3]thiazin-2-yl)[4-(trifluoromethoxy)phenyl]amino}propanenitrile (25) and 3-[(2,2-difluoro-2H-1

the coupling of electron-rich and electron-poor aryl halides with both primary and secondary alkyl amines. In this study, it is reported that a Ni(II)-bipyridine complex catalyzes efficient C–N coupling of aryl chlorides and bromides with various primary and secondary alkyl amines under direct excitation with light. Intramolecular C–N coupling is also demonstrated. The feasibility and applicability of
