Cephem compounds of the formula: ##STR1## wherein Q stands for a nitrogen atom or CH, R.sup.1 stands for a hydrogen atom or an optionally substituted lower alkyl group, R.sup.2 stands for a hydrogen atom or a lower alkyl group, A stands for a sulfur atom or NH, and n denotes an integral number ranging from 2 to 4, or salts thereof, and processes for producing them. The compounds (I) or salts thereof show not only excellent antibacterial activities against a wide range of pathogenic bacteria from gram-positive to gram-negative ones, including a variety of strains isolated clinically but also hydrophilic properties, and therefore they are excellent antibiotic substances having desirable water-solubility when used as injections.
