Cefozopran hydrochloride is a third-generation cephalosporin that was launched for the treatment of severe infections in immunocompromised patients caused by staphylococci and enterococci. While it shows a very broad antibacterial spectrum against Gram-positive and Gram-negative organisms, it is particularly potent against S. aureus, Enterococcus faecalis, P. aeruginosa, and Citrobacter freundii. It is resistant to hydrolysis by most chromosomal and plasmid mediated β-lactamases and is reported to be active against respiratory, urinary tract, obstetrical, gynecological, soft tissue, and surgical infections. Similar to β-lactams, cephalosporins interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBP’s are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Resistance to cephalosporins is commonly due to cells containing plasmid encoded β-lactamases.

Cadrofloxacin hydrochloride was studied for the treatment of bacterial infections. The compound was originally developed by UBE and Daiichi Sankyo. However, this study was discontinued. The compound currently was developed by Hengrui. Cadrofloxacin showed potent bactericidal activity against S. aureus, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa.

Nitroscanate (trade name Lopatol) is a medium-spectrum anthelmintic used on dogs and cats. It is available in the form of tablets for oral administration. It is not used on livestock. Nitroscanate is effective against the major gastrointestinal roundworms (nematodes) of dogs and cats (e.g.Toxocara canis, Toxocara cati, Ancylostoma spp, Uncinaria stenocephala) and tapeworms (e.g. Dipylidium caninum, Echinococcus granulosus, Taenia spp, etc.). The molecular mode of action of nitroscanate has not been elucidated. It is assumed that it acts as an uncoupler of the oxidative phosphorylation in the cell mitochondria, which disturbs the production of ATP, the cellular "fuel". This impairs the parasites motility and probably other processes as well.

Moroxydine is an antiviral drug discovered in the 1950’s which was shown to be active against DNA and RNA viruses. Moroxydine analogues are potent anti-hepatitis C virus (HCV) agents.

Ttioxidazole has broad spectrum activity against gastrointestinal nematodes. Tiox (tioxidazole) Paste is indicated for removal of mature large strongyles (Strongylus edentatus, S.equinus , and S.vulgaris ), mature ascarids (Parascaris equorum and immature (4th larval stage) pinworms (Oxyuris equi), and mature small strongyles (Triodontophorus spp). Ttioxidazole is a tubulin polymerization inhibitor.

TERIZIDONE, a structural analog of cycloserine, is a broad spectrum antibiotic used in the treatment of multidrug-resistant tuberculosis. However, its effectiveness is widely debated. Terizidone acts by inhibiting cell wall synthesis by competitively inhibiting two enzymes, L-alanine racemase and D-alanine ligase, thereby impairing peptidoglycan formation necessary for bacterial cell wall synthesis.

Temocillin was marketed by Beecham Pharmaceuticals in the UK in the 1980s but achieved little commercial success and was withdrawn, though it remained available via the manufacturer’s medical department. Presently licensed to Eumedica, temocillin is being re-launched in the UK and Belgium for treating UTI, sepsis, and respiratory infections by ESBL (Extended-spectrum beta-lactamases) and AmpC-producing Enterobacteriaceae. It acts by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls. It irreversibly binds to the active site of specific transpeptidases and carboxypeptidases known as Penicillin Binding Proteins (PBP), preventing peptidoglycan production.

Cefalonium is a 1st generation cephalosporin with a broad spectrum of actvity against Gram-positive and Gram-negative bacterias. The drug inhibits the bacterial cell wall synthesis by binding to penicillin binding proteins. Cefalonium is approved for routine dry cow therapy to treat existing sub-clinical infections and to prevent new infections which occur during the dry period.

Noxythiolin is an antimicrobial agent. It can be used for irrigation procedures with noxythiolin solution to reduce the risk of sepsis in patients undergoing percutaneous drainage procedures. It seems mechanism of action is based on ability of noxythiolin to decompose in solution to liberate most of its formaldehyde.

Sulbentine has a broad spectrum effect and is used especially in dermatomycoses treatment in the treatment of various forms.
