摘要

The invention relates to a DGAT inhibitor of formula (I), including any stereochemically isomeric form thereof, wherein A represents CH or N; the dotted line represents an optional bond in case A represents a carbon atom; X represents -O-C(=O)-; -C(=O)-C(=O)-; -NR^X-C(=O)-; -Z-C(=O)-; -Z-NR^X-C(=O)-; -C(=O)-Z-; -NR^X-C(=O)-Z-; -C(=S)-; -NR^X-C(=S)-; -Z-C(=S)-; -Z-NR^X-C(=S)-; - C(=S)-Z-; -NR^X-C(=S)-Z-; Z represents a bivalent radical selected from C1-6alkanediyl, C2-6alkenediyl or C2-6alkynediyl; wherein each of said C1-6alkanediyl, C2-6alkenediyl or C2-6alkynediyl may optionally be substituted; and wherein two hydrogen atoms attached to the same carbon atom in C1-6alkanediyl may optionally be replaced by C1-6alkanediyl; Y represents -C(=O)-NR^X- or -NR^X-C(=O)-; R¹ represents adamantanyl, C3-6cycloalkyl; aryl¹ or Het¹; R² represents C3-6cycloalkyl, phenyl, naphtalenyl, 2,3-dihydro-1,4-benzodioxinyl, 1,3-benzodioxolyl, 2,3- dihydrobenzofuranyl or a 6-membered aromatic heterocycle containing 1 or 2 N atoms, wherein said C3-6Cycloalkyl, phenyl, naphtalenyl, 2,3-dihydro-1,4-benzodioxinyl, 1,3-benzodioxolyl or heterocycle may optionally be substituted; R⁷ represents hydrogen, halo, C1-4alkyl, C1-4alkyl substituted with hydroxyl; provided that the following compounds (II), (III) are excluded; a N-oxide thereof, a pharmaceutically acceptable salt thereof or a solvate thereof. The invention further relates to methods for preparing such compounds, pharmaceutical compositions comprising said compounds as well as the use as a medicine, as a DGAT inhibitor, of said compounds.
