Phenylcyclobutylamide derivatives and their optical isomers, the preparing processes and the uses thereof, which includes the compounds of formula (I), their pure stereoisomers and their pharmaceutically acceptable salts. In formula (I), R is H, formacyl, acetyl, haloacetyl, benzoyl, benzyloxy carbonyl (Cbz), t-butoxy carbonyl (Boc), or 9-fluorenyl methoxyl carbonyl (Fmoc). The present novel compounds have pharmaceutical activity and are prepared by condensation reaction of racemic, levo- or dextro-demethyl Sibutramine and racemic or D/L isoleucine under a mild condition. It is demonstrated that the present compounds have effect of losing weight to obese mode rats in different level and the effect is better than Sibutramine by the animal experiments. So the medicaments prepared by the present compounds or the medicaments prepared by the compositions of the present compounds and other pharmaceutical activity compounds may be used for treating obesity.
苯基环丁酰胺衍生物及其光学异构体,其制备方法和用途,包括式(I)化合物,其纯立体异构体和其药学可接受的盐。在式(I)中,R为H,甲酰基,乙酰基,卤代乙酰基,苯甲酰基,苄氧羰基(Cbz),叔丁氧羰基(Boc)或9-芴甲氧羰基(Fmoc)。这些新型化合物具有药理活性,是通过在温和条件下将外消旋、左旋或右旋去甲基西布曲明和外消旋或D/L异亮氨酸进行缩合反应制备的。动物实验表明,这些化合物对不同程度的肥胖模式大鼠有减肥作用,且效果优于西布曲明。因此,通过这些化合物制备的药物或通过这些化合物和其他药理活性化合物组成的药物可以用于治疗肥胖症。
