Pharmaceutical composition containing quinoline or quinazoline derivatives

A compound of the formula (I'):

• ##STR333## wherein Y is C-G in which G is an amidated carboxyl group, or hydroxymethyl group;
• R is represented by a group of the formula:
• --CH.sub.2 --X.sup.1 --Z.sup.1
• wherein X.sup.1 is an oxygen atom, optionally oxidized sulfur atom or --(CH.sub.2).sub.m -- in which m is an integer of 1 to 5, and Z.sup.1 is an optionally substituted hydrocarbon group, optionally substituted heterocyclic group or optionally substituted amino group;
• provided that X.sup.1 is not --(CH.sub.2).sub.m -- when Z.sup.1 is all optionally substituted hydrocarbon group;
• X is an oxygen atom or optionally oxidized sulfur atom;
• n is 0;
• k is 0 or 1;
• each of the rings A and B may optionally be substituted;
• G and R may be linked together to form a 5-membered ring, wherein the resulting compound is represented by the formula (II) or (III):
• ##STR334## wherein R.sup.3 is an optionally substituted hydrocarbon group or optionally substituted heterocyclic group;
• Z.sup.1 is an optionally substituted hydrocarbon group, optionally substituted heterocyclic group or optionally substituted amino group;
• k, ring A and ring B are as defined above:
• or a pharmaceutically acceptable salt thereof.
