    摘要: The present invention relates to new cephalosporins of the formula

    wherein
       R¹ and R² are hydrogen or carboxy, with the proviso that both cannot be the same;
       R³ is hydrogen or acetyl; and
       R⁴ is a radical selected from the group consisting of

    or -CH=CH-CH₂-R⁶
    in which n is 1 or 2, R⁵ is hydrogen or acetyl, and R⁶ is hydrogen, a lower C₁₋₃ alkyl, or a radical selected from the group consisting of

    in which n and R⁵ are as defined above.
    In another aspect, this invention relates to processes for the preparation of the compounds of Formula I, to pharmaceutical compositions containing at least one compound of Formula I, and to intermediates in their preparation.

    摘要: As new antibacterial compounds are provided a cephalosporin derivative having the general formula (I)
    wherein R¹ is a lower alkyl group, a lower alkoxymethyl group or a lower alkenyl group, and R² and R³ are each a hydrogen atom or a lower alkyl group, and pharmaceutically acceptable salt thereof.
    This new cephalosporin derivative of the formula (I) is useful as an orally administrable antibacterial agent which exhibits an excellent antibacterial activity, high absorbability through the digestive tracts of animal and high urinary recovery thereof.
