This invention relates to a novel class of compounds which are cysteine protease inhibitors, including but not limited to, inhibitors of cathepsins K, L, S and B. These compounds are useful for treating diseases in which inhibition of bone resorption is indicated, such as osteoporosis.
The present invention is concerned with aryl-4-ethynyl-isoxazole derivatives of formula I
wherein R
1
to R
5
are as described in the specification and pharmaceutically acceptable salt thereof. This class of compounds has high affinity and selectivity for GABA A α5 receptor binding sites, being useful as a cognitive enhancer or for the treatment of cognitive disorders like Alzheimer's disease.
本发明涉及式I的芳基-4-乙炔-异恶唑衍生物,其中R1至R5如规范中所述,并且其药用盐。这类化合物具有高亲和力和选择性结合到GABA A α5受体结合位点,可用作认知增强剂或用于治疗阿尔茨海默病等认知障碍。

Various 3-alkynylpyridazines have been prepared by cross-coupling of 3-halopyridazines and monosubstituted acetylenes in Et2NH with Pd (PPh3)2Cl2-CuI as a catalyst. Though the alkynylation of 3-chloropyridazine 1-oxides afforded 3-alkynylpyridazine 1-oxides, attempts to obtain 3-chloropyridazine 2-oxides were unsuccessful. N-Oxidation of 3-alkynylpyridazines with m-chloroperbenzoic acid yielded their 1-oxides exclusively
