It exerts antibacterial activity by inhibiting the synthesis of bacterial cell walls and has antibacterial activity against aerobic Gram-positive bacteria (such as Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes) and aerobic Gram-negative bacteria (such as Escherichia coli, Klebsiella pneumoniae, Proteus)

It inhibits the synthesis of bacterial cell wall, has good permeability to the cell wall, is stable to β-lactamase, has a strong affinity for penicillin-binding proteins 1A, 1B and 3, and can strongly inhibit the cross-linking of cell wall mucopeptides.

It inhibits the synthesis of bacterial cell walls, thus playing a bactericidal role. It has good permeability to the cell wall, is stable to β-lactamase, has a strong affinity for penicillin binding proteins 1A, 1B and 3, and can strongly inhibit the cross-linking of cell wall mucopeptides.

It has high resistance to β-lactamase and has strong antibacterial activity against β-lactamase-producing bacteria; it has excellent antibacterial activity against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, indole-negative Proteus, and also has strong antibacterial activity against other bacteria that are not sensitive to cephalosporins and penicillins, such as indole-positive Proteus; it shows excellent antibacterial effect against anaerobic bacteria such as Bacteroides, Peptococcus and Streptococcus; it strongly inhibits the cell wall synthesis of bacteria in the proliferation stage and exerts a bactericidal effect.
