Indoline compounds represented by the general formula: ##STR1## wherein R.sup.1 represents the group ##STR2## R.sup.2 represents a phenyl group which may be substituted or an aromatic heterocyclic group, and R.sup.3 represents hydrogen, a halogen, or a lower alkyl group, hydroxyl group, lower alkoxy group, carbamoyl group or lower alkoxycarbonyl group, and physiologically acceptable salts thereof, and their solvates, as well as 5-HT.sub.3 receptor antagonists containing them as effective components. The indoline compounds of the invention have stronger antagonism against intestinal 5-HT.sub.3 receptors than known 5-HT.sub.3 receptor antagonists and also have excellent sustained action, making them useful as prophylactic or therapeutic agents against vomiting or irritancy induced by chemotherapy or radiation, irritable bowel syndrome, diarrhea, and the like.
本发明涉及一种由一般式表示的吲哚啉化合物:##STR1##其中R.sup.1代表基团##STR2##R.sup.2代表可能被取代的苯基或芳香族杂环基团,R.sup.3代表氢、卤素或较低的烷基、羟基、较低的烷氧基、氨基甲酰基或较低的烷氧羰基基团,以及其生理上可接受的盐和溶剂化物,以及含有它们作为有效成分的5-HT.sub.3受体拮抗剂。本发明的吲哚啉化合物对肠道5-HT.sub.3受体具有比已知的5-HT.sub.3受体拮抗剂更强的拮抗作用,并且具有出色的持续作用,因此它们可用作预防或治疗化疗或放射治疗引起的呕吐或刺激性、肠易激综合征、腹泻等的药物。
