Abstract
The invention provides new N-imidazolyl derivatives of substituted tetrahydrocarbazoles and cyclopent[b]indoles of general formula (I) ##STR1## wherein n is 1 or 2; p is an integer of 1 to 4; A is a straight or branched C.sub.1 -C.sub.4 alkylene chain; B is a direct linkage, a straight or branched, unsaturated or saturated C.sub.1 -C.sub.4 alkylene chain; Q is a direct linkage or a straight or branched C.sub.1 -C.sub.4 alkylene chain; each of R.sub.1 and R.sub.2 independently is hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkylthio, C.sub.1 -C.sub.4 alkylsulfonyl, halogen or trihalomethyl; each of R.sub.3 and R.sub.5, independently is hydrogen or C.sub.1 -C.sub.4 alkyl; R.sub.4 is --OR.sub.6 or --N(R.sub.6,R.sub.7) group, wherein each of R.sub.6 and R.sub.7 independently is hydrogen, C.sub.1 -C.sub.4 alkyl, phenyl or benzyl; or a pharmaceutically acceptable salt thereof, which are useful in the treatment of a disease state in which an enhancement of TxA.sub.2 synthesis exerts a pathogenic effect.
