R
4
or NOR
6
; R
3
is H, alkyl, aralkyl, alkynyl, trifluoroacetyl, t-butoxycarbonyl or an acyl group; R
4
is H, alkyl, aralkyl, or alkynyl; R
6
is H or C
1
-C
4
alkyl; R
1
and R
2
are each independently H, alkyl, aralkyl, or alkynyl; the curved line drawn from S to the center of the phenyl ring and the straight line drawn from N to the center of the ring indicate that S and N are part of a 5 membered ring which shares two carbons with the phenyl ring; and the dashed line drawn from the carbon atom on the cyclopentyl ring to Y represents a bond when Y is O or NOR
6
and is absent when Y is NR

, and wherein wherein X is H or O; and R
5
is H, alkyl, trifluoroacetyl, t-butoxycarbonyl or an acyl group, or an enantiomer, or a tautomer, or a pharmaceutically acceptable salt thereof, a process for preparing the compounds and a method of treating Parknison's disease, multiple sclerosis or depression with the compounds of the invention.
本发明提供一种具有以下结构的化合物:其中Y为O、NR3R4或NOR6;R3为H、烷基、芳基烷基、炔基、三氟乙酰基、叔丁氧羰基或酰基;R4为H、烷基、芳基烷基或炔基;R6为H或C1-C4烷基;R1和R2各自独立地为H、烷基、芳基烷基或炔基;从S到苯环中心画的弯线和从N到环中心画的直线表示S和N是一个共享两个碳原子的5元环的一部分;从环戊基环上的碳原子到Y画的虚线表示Y为O或NOR6时为键,当Y为NR3R4时则不存在该键;其中X为H或O;R5为H、烷基、三氟乙酰基、叔丁氧羰基或酰基,或其对映体、互变异构体或药学上可接受的盐,以及制备该化合物的方法和使用该化合物治疗帕金森病、多发性硬化症或抑郁症的方法。
