摘要:
A compound having the general formula (I) is derived from a cephalosporin; ##STR1## wherein R' is a hydrogen atom, an alkyl group having 1 to 4 atoms or an alkali metal and R is --CH.sub.2 COOR', --CH.sub.2 CH.sub.2 SR', ##STR2## or --CH.sub.2 CH.sub.2 COOR' wherein R' is defined above. A pharmaceutical composition containing the compound is excellent in an antibacterial activity, the activity being recovered by the action of an activating enzyme in a living body although the compound per se shows a low activity against the beneficial bacterial colonies in a living body.
