The present invention provides a compound of formula (I), or a pharmaceutically acceptable salt or solvate thereof, wherein: Y is selected from C or N; X is selected from O or S; R1 is selected from hydrogen or methyl; Z is CR2R3, wherein R2 and R3 are each independently selected from hydrogen and (1-5C)alkyl, or R2 and R3 are taken together with the carbon atom to which they are attached to form a cyclopropyl or cyclobutyl ring; Z1 is selected from CR4R5, O, S, C(O) or NR6, wherein R4 and R5 are each independently selected from hydrogen, OH, (1-5C)alkyl and phenyl, or R4 and R5 are taken together with the carbon atom to which they are attached to form a cyclopropyl ring, and R6 is selected from hydrogen and (1-5C)alkyl, provided that one, but not both, of Z and Z1 is CH2.
本发明提供了式(I)的化合物,或其药学上可接受的盐或溶剂,其中:Y从C或N中选择;X从O或S中选择;R1从氢或甲基中选择;Z为CR2R3,其中R2和R3各自独立地选择自氢和(1-5C)烷基,或R2和R3与它们连接的碳原子一起形成环丙基或
环丁基环;Z1从CR4R5,O,S,C(O)或NR6中选择,其中R4和R5各自独立地选择自氢,OH,(1-5C)烷基和苯基,或R4和R5与它们连接的碳原子一起形成环丙基环,R6从氢和(1-5C)烷基中选择,但Z和Z1中的一个而不是两个是
CH2。
