β-lactam antibiotic

Methicillin sodium salt is the sodium salt form of methicillin, a semisynthetic beta-lactam penicillin antibiotic with beta-lactamase resistant activity.

Ampicillin Trihydrate (NCI-C56086), a broad-spectrum semisynthetic derivative of aminopenicillin, is a β-lactam antibiotic.

Cefsulodin sodium (Sulcephalosporin) hydrate is a β lactam antibiotic.

Aztreonam (SQ-26,776), a monocyclic beta-lactam antibiotic originally isolated from Chromobacterium violaceum, possesses bactericidal activity.

Ceftazidime (GR20263) is a beta-lactam, cephalosporin antibiotic with bactericidal activity.

Imipenem monohydrate (Imipenem) is a carbapenem antibiotic isolated from the microorganism Streptomyces cattleya, and is a β lactam antibiotic. Imipenem monohydrate acts on the bacterial cell wall, and is a broadly effective inhibitor of a wide range of Gram-positive and negative bacteria.

Ceftibuten dihydrate (Sch-39720 dihydrate) is the dihydrate form of ceftibuten, and is a third-generation cephalosporin with antibacterial activity.

Cephalothin is a beta-lactam antibiotic, inhibits class C β-lactamase AmpC (Ki: 0.32 μM).

Amoxicillin Sodium (Clavulanate) is a moderate- spectrum, bacteriolytic, β-lactam antibiotic.

Ampicillin sodium (Domicillin) is a broad-spectrum β -lactam antibiotic. Ampicillin sodium combates a variety of Gram-positive and Gram-negative bacteria.

Mezlocillin Sodium (Baycipen) is a penicillin beta-lactam antibiotic used in the treatment of bacterial infections caused by susceptible, usually gram-positive, organisms.

Ceftriaxone Sodium is a broad-spectrum β-lactam tertiary cephalosporin antibiotic with anti-inflammatory, antitumor, antibacterial, and antioxidant activities.Ceftriaxone Sodium is a covalent GSK3β and Aurora B inhibitor used in the study of sepsis and infective endocarditis.

L-(+)-Ampicillin is an isomer of Ampicillin. Ampicillin is a β-lactam antibiotic used for treating bacterial infections.

Dicloxacillin Sodium hydrate is a narrow-spectrum β-Lactam antibiotic of the penicillin class, used to treat infections caused by susceptible Gram-positive bacteria.

Cefmetazole is a second-generation semi-synthetic β-lactam cephalosporin antibiotic with antimicrobial activity.

Clavulanate lithium (Clavulanic acid lithium) is an inhibitor of β-lactamase.

Sulbactam (CP45899) is a semi-synthetic beta-lactamase inhibitor. The beta-lactam ring of sulbactam irreversibly binds to beta-lactamase at or near its active site, thereby blocking enzyme activity and preventing metabolism of other beta-lactam antibiotics by the enzyme. Combining this agent with a beta-lactamase susceptible antibiotic, such as penicillins or a cephalosporin, to treat infections caused by beta-lactamase producing organisms, results in a decreased turnover rate of the beta-lactamase sensitive antibiotic and enhances its antibacterial activity.

Penicillin G procaine hydrate is a compound formulation combining the antibiotic Penicillin G and the local anaesthetic procaine, serving to release the drug slowly and alleviate pain, with inhibitory activity against Gram-positive bacteria.

Clavulanic Acid(RX-10100), a major beta-lactam antibiotic produced by the organism Streptomyces claveris, is a potent bacterial beta-lactamase inhibitor used in the study of infections caused by bacteria. Clavulanic Acid has a broad spectrum of biological activity and is active against a wide variety of Gram-positive and Gram-negative bacteria.

MLEB-22043 is a synthetic siderophore-monocyclic β-lactam conjugate which enters bacteria through TonB-dependent transport proteins utilizing its siderophore component, subsequently exerting antibacterial activity via its β-lactam portion. This compound acts as a broad-spectrum antibiotic, exhibiting significant inhibitory activity against pathogens such as Klebsiella pneumoniae, Escherichia coli, Acinetobacter baumannii, and Pseudomonas aeruginosa.

Tigemonam is an orally administered monocyclic β-lactam antibiotic effective at inhibiting many bacterial strains at concentrations of 1 microgram ml or lower. It targets Escherichia coli, Klebsiella spp., Enterobacter aerogenes, Citrobacter diversus, Proteus spp., Providencia spp., Aeromonas hydrophila, Salmonella spp., Shigella spp., Serratia marcescens, and Yersinia enterocolitica.

Piperacillin hydrate is a semisynthetic broad-spectrum β-lactam antibiotic. It exhibits potent bactericidal activity against Gram-negative bacteria and some Gram-positive bacteria by targeting penicillin-binding proteins. Piperacillin hydrate is frequently combined with the β-lactamase inhibitor Tazobactam for enhanced efficacy.

Dicloxacillin (INN), a narrow-spectrum β-Lactam antibiotic of the penicillin class, is used against beta-lactamase-producing organisms such as Staphylococcus aureus, which would otherwise be resistant to most penicillins.

Cephamycin C (CepC) is a nontoxic β-lactam antibiotic distinguished by its superior resistance to β-lactamases compared to other cephalosporins.
