Title (EN) CEPHALOSPORIN ESTERS WHICH ARE USEFUL AS ANTIBIOTICS
(FR) ESTERS DE CEPHALOSPORINE UTILES EN TANT QU'ANTIBIOTIQUES
Abstract:
(EN) The present invention provides cephalosporin esters of formula (I), wherein R1 is a disulfide group, and R2 is the ending group for the esters. These compounds are useful as antibiotics for treating warm-blooded animals to combat pathogenic bacterial infections which cause diseases such as the commonly known 'shipping fever'.
(FR) Esters de céphalosporine de la formule (I), dans laquelle R1 représente un groupe disulfure, et R2 représente le groupe de terminaison des esters. Ces composés sont utiles en tant qu'antibiotiques utilisés dans le traitement d'animaux à sang chaud afin de combattre les infections bactériennes pathogènes provoquant des maladies telles que la 'pasteurellose du bétail' bien connue.
