Ceftriaxone

Ceftriaxone (Ro 13-9904 free acid) is a broad spectrum β-lactam third-generation cephalosporin antibiotic, which has good antibacterial activity against a variety of gram-negative and positive bacteria. Ceftriaxone is a covalent inhibitor of GSK3β with IC50 value of 0.78 μM. Ceftriaxone is an inhibitor of Aurora B. Ceftriaxone has anti-inflammatory, antitumor and antioxidant activities. Ceftriaxone can be used in the study of bacterial infections and meningitis[1][2][3][4][5][6][7].
