The invention relates to a method of treating or preventing Parkinson's disease in a subject comprising administering a compound of Formula I
wherein, R1 is —NHC(O) C3-6 cycloalkyl and R2 is hydrogen;
or R1 and R2 along with the carbon atoms to which they are attached form a six membered aromatic ring, wherein the ring is substituted with one or more groups selected from hydrogen, halogen and C1-6 alkyl;
R3 and R4 are independently selected from group comprising hydrogen, halogen, C1-3 alkyl, OC1-3 alkyl, NO2, SC1-3, alkyl, C1-3, haloalkyl, OC1-3 haloalkyl, and SC1-3 haloalkyl; or a pharmaceutically acceptable salt thereof.
本发明涉及一种治疗或预防受试者帕金森病的方法,包括给药式 I 的化合物
其中,R1 为-NHC(O) C3-6 环烷基,R2 为氢;
或 R1 和 R2 与它们所连接的碳原子一起形成一个六分子芳环,其中该环被一个或多个选自氢、卤素和 C1-6 烷基的基团取代;
R3 和 R4 独立地选自氢、卤素、C1-3 烷基、OC1-3 烷基、NO2、SC1-3 烷基、C1-3 卤代烷基、OC1-3 卤代烷基和 SC1-3 卤代烷基组成的基团;或其药学上可接受的盐。
