The present invention provides condensed quinoline compounds represented by the following general formula (I): ##STR1## in which Z is NH, X is hydrogen, L is lower alkoxy, M is NHQ, Q is --SO.sub.2 CH.sub.3, Y is --NHR, and R is: ##STR2## These compounds are effective for inhibiting KB-cell growth and prolongation of the life span of mice implanted with tumor P-388.

Condensed quinoline system N-glycosides

Disclosed is a novel arylalkylamine derivative represented by the formula (I) ##STR1## wherein X represents --O--, --CH.sub.2 -- or --NR.sup.3 -- in which R.sup.3 represents hydrogen or lower alkyl;

Arylalkylamine derivatives

Novel indoloquinoline compounds of formula (I), benzo(b)acridines of formula (II) and benzo(c)acridines of formula (III) have carcinostatic activities. The compounds, processes for preparing the compounds via nucleophilic aromatic substitution, and carcinostatic compositions containing the same are disclosed. ##STR1##

Carcinostatic composition comprising indolquinolines

The present invention provides a quinoline base compound represented by the following general formula (1) of: ##STR1## wherein X is CH.sub.2, O or S. Further provided are the process for the preparation of the aforementioned quinoline base compound and an anticancer agent including the same as a pharmacologically efficacious component.

Quinoline base compound, process for the preparation thereof and

New tropolone derivatives of the general formula: ##STR1## wherein R.sup.1 represents H or an alkyl group, R.sup.2 represents an alkyl, aryl, aralkyl or heterocyclic group and R.sup.3 represents an alkoxyl, aryl or heterocyclic group or a group of the formula: ##STR2## or R.sup.2 and R.sup.3 may form together a part of a heterocyclic group, their metal complex salts, processes for the preparation thereof and the use thereof as anti-tumor agents.
