A series of new substituted benzamides has been synthesized and evaluated for dopamine antagonist activity and for antagonism of cisplatin-induced emesis in the dog and in the ferret. It was found that modification of the 2-methoxy substituent of metoclopramide was detrimental to dopaminergic D2 antagonism but not necessarily to antagonism of cisplatin-induced emesis. A number of analogues having a
合成了一系列新的取代的苯甲酰胺,并对狗和雪貂中多巴胺拮抗剂的活性以及顺铂诱导的呕吐的拮抗作用进行了评估。发现对甲氧氯普胺的2-甲氧基取代基的修饰不利于多巴胺能D2拮抗作用,但不一定不利于顺铂诱导的呕吐。具有β-酮基,β-羟基,β-甲氧基,β-亚氨基或β-不饱和烷氧基取代基而不是甲氧基的许多类似物已显示出与甲氧氯普胺同等或更好的呕吐保护作用。同时,在体外([3H] spiperone结合)和体内试验(大鼠僵直症,阿扑吗啡对大鼠的定型作用的拮抗作用以及阿扑吗啡对呕吐的拮抗作用)中,发现这些化合物都没有多巴胺能D2拮抗作用。狗)。
