Compounds according to Formula (I) or a pharmaceutically acceptable salt thereof are GABA-A Alpha 5 ligands useful for enhancing cognition:
where A is C1-6alkyl, C2-6alkenyl, C2-6alkynyl, C3-6cycloalkyl, arylC1-6alkyl, or aryl wherein the aryl group is optionally substituted by halogen, C1-6alkyl, CF3, CN, NO2 or NH2, NR1R10, S(O)pR1, heteroarylC1-6alkyl or heteroaryl where heteroaryl is a 5- or 6-membered heteroaromatic ring as defined for B; and B is phenyl or a 5-membered ring having one or two unsaturations containing 1, 2, 3, or 4 heteroatoms chosen from O, N and S provided that not more than one heteroatom is other than N, a 6-membered heteroaromatic ring containing 1, 2, 3 or 4 nitrogen atoms, each of which rings is optionally substituted by one or more substituents.
根据公式(I)或其药学上可接受的盐,化合物为GABA-A Alpha 5配体,用于增强认知:其中A为C1-6烷基,C2-6烯基,C2-6炔基,C3-6环烷基,芳基C1-6烷基,或芳基,其中芳基可选择性地由卤素,C1-6烷基,CF3,CN,NO2或NH2,NR1R10,S(O)pR1,杂芳基C1-6烷基或杂芳基取代,其中杂芳基为定义为B的5-或6-成员杂芳环;B为苯或含有一或两个不饱和度的5-成员环,其中包含1、2、3或4个氧、氮和硫的杂原子,前提是不超过一个杂原子不是N,含有1、2、3或4个氮原子的6-成员杂芳环,每个环可选择性地取代为一个或多个取代基。
