Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
98 words
A pharmaceutical composition for the treatment of bacterial infections comprising an antibacterially effective amount of a compound of the formula: ##STR31## wherein R is a heterocyclic ring system comprising oxygen, nitrogen or sulfur as the hetero atom and containing six ring members in the hetero ring, said system being a monocyclic or a fused benzo bicyclic system and being unsubstituted or substituted with a member selected from the group consisting of alkyl of 1 to 6 carbon atoms, carbalkoxy of 1 to 6 carbon atoms in the alkoxy group, phenyl and oxo, in combination with a pharmaceutical carrier.
Claim 2
Dependent Claim
