Oxygenic heterocyclic compounds represented by general formula (I) or pharmacologically acceptable salts thereof, wherein n is an integer of 1 to 4; R1, R2, R3 and R4 are the same or diffrent and each represents hydrogen, optionally substituted lower alkyl, etc.; R5 represents hydrogen or halogeno; R6 represents hydroxy or optionally substituted lower alkoxy; D represents (1): -C(R8)(R9)-X- or bond (2): -Y-ZR14; and R7 represents (1), optionally substituted lower alkyl, optionally substituted cycloalkyl, polycycloalkyl, optionally substituted aryl, optionally substituted aralkyl, optionally substituted aromatic heterocycle, optionally substituted heterocycle, or pyridine N-oxide, (2), (3): -Y-Z-(CH2)m-N(R16a)R16b, or (4): -Y-CON(R17a)R17b.

L'invention concerne des composés hétérocycliques d'oxygène représentés par la formule générale (I) ou leurs sels pharmacologiquement acceptables. Dans la formule (I), n est entier compris entre 1 et 4; R?1¿, R?2¿, R?3¿ et R?4¿ sont identiques ou différents et représentent chacun hydrogène, alkyle inférieur éventuellement substitué, etc.; R?5¿ représente hydrogène ou halogéno; R?6¿ représente hydroxy ou alcoxy inférieur éventuellement substitué; D représente (1) -C(R?8¿)(R?9¿)-X- ou une liaison (2); R?7¿ représente (1), alkyle inférieur éventuellement substitué, cycloalkyle éventuellement substitué, polycycloalkyle, aryle éventuellement substitué, aralkyle éventuellement substitué, hétérocycle aromatique éventuellement substitué, hétérocycle éventuellement substitué, ou pyridine N-oxyde, (2) -Y-ZR?14¿, (3) -Y-Z-(CH¿2?)¿m?-N(R?16a¿)R?16b¿, ou (4) -Y-CON(R?17a¿)R?17b¿.
