E4465 Potassium clavulanate cellulose Potassium clavulanate cellulose (Potassium clavulanate:cellulose (1:1)) is a mixture of potassium clavulanate and cellulose, is a bacterial β-lactamase inhibitor. Potassium clavulanate with the combination of amoxicillin can be used for the research of different infections caused by bacteria, such as sinusitis, pneumonia, ear infections, bronchitis, urinary tract infections, and infections of the skin.
E0167 Tazobactam Sodium

Tazobactam (Tazobactam acid, Tazobactamum) Sodium is a beta-lactamase inhibitor that prevents the breakdown of other antibiotics by beta-lactamase enzyme producing organisms.
E4472 Clavulanic acid Clavulanic acid is a naturally occurring, powerful bacterial β-lactamase inhibitor. The beta-lactam ring found in clavulanic acid binds to the active site of beta-lactamase, resulting in enzyme inactivation and enhancing the antibacterial activity of beta-lactam antibiotics like amoxicillin.
S0074 Relebactam Relebactam (MK-7655) is a potent inhibitor against KPC-2, class A and class C (AmpC) β-lactamases.
E4838New Cefuroxime Cefuroxime (Kefurox) is an orally active, second-generation, broad-spectrum cephalosporin antibiotic with increased stability to β-lactamase. Cefuroxime exhibits broad-spectrum activity against Gram-positive bacteria including penicillinase-producing staphylococci and non-β-lactamase-producing gram-negative bacteria.
S4620 Cefuroxime sodium Cefuroxime Sodium is a cephalosporin effective against gram-positive and gram-negative bacteria with resistance to β-lactamase.
S3077 Tazobactam Tazobactam (Tazobactam acid, Tazobactamum) is a β-lactamases Inhibitor with antibacterial activity. It also inhibits the class D oxacillinase OXA-2. It is used in combination with piperacillin and other β-lactam antibiotics to broaden their spectrum and enhance their effect.
