Abstract

A set of 22 cephalosporine derivatives were used in a structure-activity study to identify features correlating with an­tibacterial ac!ivity against Escherichia coli. Sorne quantitative rela­tionships between hydrophobics and electronics properties of R3 and R1 substituents with the activity were identified. More hydro­phobics substituents at posirion C3 decrease antibacterial activity. It was concluded that the presence of a proton acceptor atom directly bonded to the C2 of the acetamide group in R7 improved the activ­ity. It was observed that the higher is the capacity of the nitrogen 3 to donate electrons in the 2-amino-chiazol-4-il ring in R1 and the carbonil group of the 13-lactamic ring the Jesser is the activity.
