Modification of biologically active amides and amines by fluoro-containing heterocycles 10. γ-Carbolines modified by 2-trifluoromethylimidazo-[1,2-a]pyridin-3-ylpropionamide fragments

An approach to the modification of biologically active γ-carbolines by the 2-trifluoromethylimidazo[1,2-a]pyridin-3-ylpropionamide fragments was suggested, which consisted of the reaction of N-methyl-N-(2-trifluoromethylimidazo[1,2-a]pyridin-3-yl)prop-2-enamides with γ-carbolines in the presence of catalytic amounts of cesium fluoride. Method of radioligand binding was used to study effects of the synthesized 3-(1,2,3,4-tetrahydro-5H-pyrido[4,3-b]-indol-5-yl)-N-methyl-N-[2-(trifluoromethyl)imidazo-[1,2-a]pyridin-3-yl]propanamides on the neuronal NMDA-receptors.
