The present invention discloses novel aryl oxazole compounds of Formula I (I), or pharmaceutically acceptable salts thereof, which have histamine-H3 receptor antagonist or inverse agonist activity, as well as methods for preparing and using such compounds. In another embodiment, the invention discloses pharmaceutical compositions comprising compounds of Formula I as well as methods of using these compositions to treat obesity, cognitive deficiencies, narcolepsy, and other histamine H3 receptor-related diseases. Formula I (I) or a pharmaceutically acceptable salt thereof, wherein: m is independenlly at each occurrence 1, 2, or 3, Z independently represents carbon (substituted with hydrogen or the optional substituents indicated herein) or nitrogen, provided that when Z is nitrogen then R6 is not attached to Z; R1 and R2 are independently —(C1—C7) alkyl (optionally substituted with one to three halogens), or R1 and R2 and the nitrogen to which they are attached form an azetidinyl ring, a pyrrolidinyl ring, or a piperidinyl ring, wherein further the azetidinyl, pyrrolidinyl, or piperidinyl ring so formed may be optionally substituted one to three times with R5; R6 is independently at each occurrence —H, -halogen, or —CH3.
本发明揭示了新颖的芳基噁唑化合物,其化学式为I(I),或其药学上可接受的盐,具有组胺H3受体拮抗剂或反式激动剂活性,以及制备和使用这种化合物的方法。在另一实施方案中,本发明揭示了包括化合物I的药物组合物,以及使用这些组合物治疗肥胖症、认知缺陷、嗜睡症和其他组胺H3受体相关疾病的方法。其中,化合物I(I)或其药学上可接受的盐,其中:m在每个出现的位置上独立地为1、2或3,Z独立地表示碳(用氢或本文所示的可选取代基取代)或氮,但当Z为氮时,R6不与Z连接;R1和R2独立地为—(C1-C7)烷基(可选取代有一到三个卤素),或R1和R2及它们所连接的氮形成一个氮杂环、吡咯烷环或哌啶环,其中进一步形成的氮杂环、吡咯烷环或哌啶环可以用R5取代一到三次;R6在每个出现的位置上独立地为—H、-卤素或—CH3。
