The use of a compound of the formula (I) :
or a pharmaceutically acceptable acid addition salt thereof, in the manufacture of a medicament for the treatment of gastrointestinal motility disorders is described wherein R¹ is hydrogen, C₁-C₆ alkyl or C₃-C₅ alkenyl; R² is hydrogen, halogen, CF₃, C₁-C₆ alkyl or R⁴O; R³ is halogen, CF₃, C₁-C₆ alkyl, hydroxy, C₁-C₆ alkoxy,. S-(C₁-C₆) alkyl, S-trifluoromethyl, NO₂, SOn-phenyl where the phenyl is optionally substituted by hydroxy, C₁-C₆ alkoxy, halogen, CF₃, C₁-C₆ alkyl, SOn(C₁-C₆) alkyl, SOnCF₃, SOn-phenyl or SO₂NR⁵R⁶; R⁴ is hydrogen, C₁-C₆ alkyl, or C₁-C₆alkanoyl; R⁵ and R⁶ are hydrogen or C₁-C₆ alkyl; and n is 0, 1 or 2; provided R² is not hydrogen when R³ is S-phenyl in the 6-position and provided that when R² is hydroxy in the 8-position and R¹ is C₁-C₆ alkyl, R³ may be halogen or CF₃ only if it is in the 6-or 9-position.
本发明涉及使用式(I)的化合物或其药学上可接受的酸盐,制造用于治疗胃肠动力障碍的药物。其中,R¹为氢,C₁-C₆烷基或C₃-C₅烯基;R²为氢,卤素,CF₃,C₁-C₆烷基或R⁴O;R³为卤素,CF₃,C₁-C₆烷基,羟基,C₁-C₆烷氧基,S-(C₁-C₆)烷基,S-三氟甲基,NO₂,SOn-苯基,其中苯基可以选择性地由羟基,C₁-C₆烷氧基,卤素,CF₃,C₁-C₆烷基,SOn(C₁-C₆)烷基,SOnCF₃,SOn-苯基或SO₂NR⁵R⁶取代;R⁴为氢,C₁-C₆烷基或C₁-C₆酰基;R⁵和R⁶为氢或C₁-C₆烷基;n为0、1或2;前提是当R³为6-位置的S-苯基时,R²不为氢,并且当R²为8-位置的羟基且R¹为C₁-C₆烷基时,只有当R³在6-或9-位置时才能为卤素或CF₃。
