Sulbactam is a β-lactamase inhibitor useful in combination with β-lactam antibiotics to increase their potency. It irreversibly inactivates β-lactamase enzymes, preventing them from degrading β-lactam antibiotics. Sulbactam has been used in combination with ampicillin and cefoperazone to inhibit β-lactamase enzymes during Agrobacterium-mediated plant genetic modifications. It may also be used in cell signaling studies.

Tazobactam is a β-lactamase inhibitor useful in combination with β-lactam antibiotics to increase their potency. It irreversibly inactivates β-lactamase enzymes, preventing them from degrading β-lactam antibiotics. Tazobactam has been used in combination with piperacillin and a variety of other antibiotics. Tazobactam is less soluble in aqueous solution than tazobactam sodium.

Tazobactam is a β-lactamase inhibitor derived from penicillin. It is used along with β-lactam antibiotics, to prevent their degradation by β-lactamase enzymes. Tazobactam is often used with piperacillin to increase its potency. Additionally, tazobactam is used in studies regarding β-lactamase and penicillinase inhibition.
