- Modification of biologically active amides and amines with fluorine-containing heterocycles 8. γ-Carbolines modified with the 2-(2-trifluoromethylimidazo[1,2-a]pyridin-6-yl)ethyl fragment
-
An approach to modification of biologically active g-carbolines with the 2-(2-trifluoromethylimidazo[1,2-a]pyridin-6-yl)ethyl fragment was proposed. The modification involves a reaction of 2-trifluoromethyl-6-vinylimidazo[1,2-a] pyridine with g-carbolines. The effect of the compounds obtained on neuronal NMDA receptors was studied by the radioligand binding method.
