[EN] The present invention relates to compounds comprising fused oxazole or thiazole derivatives of formula (I), processes for preparing them, pharmaceutical compositions comprising said compounds and their uses as H3-receptor ligands, wherein A is a cyclic amine which is linked to the propylene group via an amino nitrogen; B is selected from the group consisting of heteroaryl, 5-8-membered heterocycloalkyl, 5-8-membered cycloalkyl; X is either N or CH; Y is either O or S. [FR] La présente invention concerne des composés comprenant des dérivés d'oxazole ou de thiazole fusionnés de formule (I), leurs procédés de préparation, des compositions pharmaceutiques comprenant lesdits composés et leurs utilisations en tant que ligands du récepteur H3. Selon l'invention, A représente une amine cyclique qui est reliée au groupement propylène par un azote amino ; B est choisi dans le groupe constitué d'un hétéroaryle, d'un hétérocycloalkyle ayant de 5 à 8 éléments, d'un cycloalkyle ayant de 5 à 8 éléments ; X représente N ou CH ; Y représente O ou S.
Acetamide Scanning around Bicyclic Thiazoles: SAR at the H3 Receptor
A surprisingly homogeneous SAR against the H3receptor was revealed for positional acetamide isomers of bicyclicthiazoles fused to various cyclic amines. Pyrroline and azepine rings were used to probe the central position of the amide. In vitro ADMET parameters were measured, and the isomer with the best overall properties was assessed in vivo.
