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.
本发明公开了具有组分I(I)的新型芳基噁唑化合物或其药学上可接受的盐,其具有组胺H3受体拮抗剂或逆向激动剂活性,以及制备和使用这些化合物的方法。在另一实施方案中,本发明公开了包括组分I化合物的药物组合物,以及使用这些组合物治疗肥胖、认知缺陷、嗜睡症和其他组胺H3受体相关疾病的方法。组分I(I)或其药学上可接受的盐,其中:m在每次出现时独立地为1、2或3,Z独立地表示碳(用氢或此处指示的可选取代基团取代)或氮,但当Z为氮时,R6不连接到Z;R1和R2独立地为-(C1-C7)烷基(可选地用一到三个卤素取代),或者R1和R2以及它们连接的氮形成氮杂环戊二烷环、吡咯环或哌啶环,进一步地,所形成的氮杂环戊二烷、吡咯环或哌啶环可以用R5取代一到三次;R6在每次出现时独立地为-H、-卤素或-CH3。
