The invention relates to the compounds of general formula (I)in which X1, X2, X3and X4represent, independently of each other, a nitrogen atom or a group C-R1; W represents an oxygen or sulfur atom; n is equal to 0, 1, 2 or 3; Y represents an optionally substituted aryl or heteroaryl; A represents the group of formula:Z1, Z2, Z3and Z4represent, independently of each other, a nitrogen atom or a group C-R2;Ra and Rb together form, with the carbon atoms that bear them, either a partially unsaturated cycloalkyl, or an aryl; or a heterocycle, or a heteroaryl, which is 5- to 7-membered, comprising from 1 to 3 heteroatoms chosen from O, S and N; this cycloalkyl, this aryl, this heterocycle or this heteroaryl possibly being substituted with one or more substituents R3; in the form of the base or of an acid-addition salt, and also in the form of hydrate or solvate.Preparation process and therapeutic use.本發明係關於通式(I)化合物其中X1,X2,X3及X4係互相獨立表示氮原子或基團C-R1;W表示氧或硫原子;n係等於0,1,2或3;Y表示視情況經取代之芳基或雜芳基;A表示下式基團:Z1,Z2,Z3及Z4係互相獨立表示氮原子或基團C-R2;Ra與Rb和帶有彼等之碳原子一起形成部份不飽和環烷基或芳基;或雜環,或雜芳基,其係為5-至7-員,包含1至3個選自O、S及N之雜原子;此環烷基、此芳基、此雜環或此雜芳基可被一或多個取代基R3取代;呈鹼或酸加成鹽之形式,以及呈水合物或溶劑合物之形式。製備方法與治療用途。
