Substituted quinoline derivatives and pharmaceutical compositions thereof

Abstract

The novel class of substituted quinolines represented by the general formula (I): ##STR1## where each of R.sub.1 and R.sub.2 separately represents H or up to three of the groups lower alkyl, halogen, CF.sub.3, CN, SO.sub.2 CH.sub.3, NO.sub.2, OH, NH.sub.2, NHSO.sub.2 R.sub.3, NHCOOR.sub.3, OR.sub.3, SR.sub.3, NHR.sub.3 or NR.sub.3 R.sub.3 (where R.sub.3 is lower alkyl optionally substituted with hydroxy, amino or ether functions), and each of R.sub.1 and R.sub.2 may additionally separately represent the substitution of an aza (--N.dbd.) group for one or two of the methine (--CH.dbd.) groups in each of the carbocyclic rings, and R.sub.1 may also represent, at positions 2', 3' or 4' only, a phenyl ring optionally further substituted with lower alkyl, halogen, CF.sub.3, CN, SO.sub.2 CH.sub.3, NO.sub.2, OH, NH.sub.2, NHCOR.sub.3, NHCOOR.sub.3, OR.sub.3, SR.sub.3, NHR.sub.3 or NR.sub.3 R.sub.3 (where R.sub.3 is lower alkyl optionally substituted with hydroxy, amino or ether functions); Y represents C(NH)NH.sub.2, NHC(NH)NH.sub.2 or NR.sub.4 R.sub.5, where each of R.sub.4 and R.sub.5 is H or lower alkyl optionally substituted with hydroxy, amino or ether functions, or R.sub.4 and R.sub.5 together with the nitrogen atom form a heterocyclic ring; and n is from 2 to 6; and the acid addition salts and 1-N-oxides thereof, possess antibacterial and antitumor properties.
