Broad-spectrum cephalosporin antibiotic resistant to beta-lactamase. It has been proposed for infections with gram-negative and gram-positive organisms, gonorrhea, and haemophilus.

7beta-aminocephalosporanic acid is the alpha,beta-unsaturated monocarboxylic acid that is the active nucleus for the synthesis of cephalosporins and intermediates. It is functionally related to a cephalosporanic acid. It is a tautomer of a 7beta-aminocephalosporanic acid zwitterion.

Ibrutinib is a small molecule that acts as an irreversible potent inhibitor of Burton’s tyrosine kinase. It is designated as a targeted covalent drug and presented as a promising activity in B-cell malignancies in clinical trials.

It has a role as an antineoplastic agent, a protein kinase inhibitor and an epidermal growth factor receptor antagonist.
