  • Cephalosporin antibiotics
    Patent number: 5223496
    Abstract: Cephalosporin compounds of Formulas II ##STR1## where R is hydrogen or a pharmaceutical cation, in which case R.sub.1 is not present, orR is hydrogen or a chemical bond when R.sub.1 is an acid addition salt anion, and R.sub.2 is (a) hydrogen, (b) a duplicate of the formula I compound to form a dimer, (c) an aminocarbonylmethyl, or (d) an --SR.sub.3 group where R.sub.3 is alkyl, cyclohexyl, phenyl, chloro-substituted phenyl, nitro-substituted phenyl, benzyl or furfuryl, have been found to be valuable as antibiotics for treating warm-blooded animals to combat pathogenic bacterial infections which cause diseases such as the commonly known "shipping fever".
    Type: Grant
    Filed: April 23, 1992
    Date of Patent: June 29, 1993
    Assignee: The Upjohn Company
