    Abstract: In the present invention there are disclosed substituted dihydropyranopyridines of the general formula I, in which =ai1-ai2=ai3-ai4= represents a bivalent radical =N-CH=CH-CH=, =CH-N=CH-CH=, =CH-CH=N-CH= or =CH-CH=CH-N=, whereby in those bivalent radicals can be optionally one or two hydrogen atoms substituted with a halogen, hydroxy, alkyl containing 1 to 6 carbon atoms or alkoxyl containing 1 to 6 carbon atoms Re1, Re2 and Re3 represent each independently on each other hydrogen or alkyl containing 1 to 6 carbon atoms, Alke1 represents alkanediyl containing 1 to 5 carbon atoms, Alke2 represents alkanediyl containing 2 to 15 carbon atoms, Q represents a five- or six-membered heterocyclic radical containing at least one nitrogen atom or the radical aa, wherein Re4 represents hydrogen, cyano, aminocarbonyl or alkyl containing 1 to 6 carbon atoms, Re5 represents hydrogen, alkyl containing 1 to 6 carbon atoms alkenyl containing 3 to 6 carbon atoms or alkynyl containing 3 to 6 carbon atoms, Re6 represents hydrogen or alkyl containing 1 to 6 carbon atoms or Re5 and Re6 together form a bivalent radical of the general formula -(CHi2)i4- or -(CHi2)i5-, and their pharmaceutically acceptable acid addition salts, N-oxides and stereochemically isomeric forms per se and for use in medicine. In the present invention there are also claimed a process for preparing those compounds and pharmaceutical preparations based thereon. The above indicated derivatives are suitable for prevention and/or therapy of disorders characterized by excessive vasodilatation, particularly migraine.
