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.
