Annelated indoleketones with an imidazolylalkyl substituent having the formula (2): ##STR1## wherein R.sub.1 is alkyl or alkoxy having 1-4 C-atoms, hydroxy, halogen, trifluoromethyl, a group R.sub.5 R.sub.6 N or R.sub.5 R.sub.6 -N-CO, wherein R.sub.5 and R.sub.6 are hydrogen or alkyl having 1-4 C-atoms or wherein R.sub.5 R.sub.6 N is a saturated 5-6 ring, and n has the value 0, 1 or 2; A is a group of formula 3, 4 or 5 ##STR2## wherein one of the groups R.sub.2, R.sub.3 and R.sub.4 is hydrogen, alkyl having 1-4 C-atoms, cycloalkyl having 3-6 C-atoms or alkenyl having 2-4 C-atoms and the two other groups, independently of each other, are hydrogen or alkyl having 1-4 C-atoms, p has the value 0-3, and q has the value 2-5. These compounds (and pharmaceutically acceptable acid addition salts thereof) have good antagonistic activity of "neuronal" 5-hydroxytryptamine(5-HT)receptors, and the lower toxicity.
具有公式(2)的带有咪唑基烷基取代基的环戊酮类吲哚,其中R.sub.1是具有1-4个碳原子的烷基或烷氧基,羟基,卤素,三氟甲基,基团R.sub.5 R.sub.6 N或R.sub.5 R.sub.6-N-CO,其中R.sub.5和R.sub.6是氢或具有1-4个碳原子的烷基,或其中R.sub.5 R.sub.6 N是饱和的5-6环,n的值为0、1或2;A是具有公式3、4或5的基团##STR2##其中R.sub.2、R.sub.3和R.sub.4中的一个是氢,具有1-4个碳原子的烷基,具有3-6个碳原子的环烷基或具有2-4个碳原子的烯基,而另外两个基团,彼此独立地,是氢或具有1-4个碳原子的烷基,p的值为0-3,q的值为2-5。这些化合物(及其药学上可接受的酸盐)具有良好的“神经元”5-羟色胺(5-HT)受体的拮抗活性,且毒性较低。
