  Synthesis and antibacterial activities of novel C(3)-aminopyrimidinyl substituted cephalosporins including against respiratory tract pathogens

  摘要：

  The variety of cephalosporins 1 and 2 which possessed C(3)-aminopyrimidinyl substituents were prepared and evaluated for their antibacterial activities. They exhibited excellent in vitro activities especially against respiratory tract pathogens such as penicillin resistant Streptococus pneumonia, Moraxella catarrhalis and Haemophilus influenza.
