Ticarcillin is a beta-lactam antibiotic that inhibits the synthesis of peptidoglycan, which is an essential component of bacterial cell walls. Ticarcillin is used for the treatment of infections caused by susceptible bacteria, such as those in the respiratory tract, urinary tract, skin and soft tissues. It can also be used to treat sepsis and meningitis. Ticarcillin has a broad spectrum of activity against Gram-positive and Gram-negative bacteria, including Enterobacteriaceae (e.g., Escherichia coli) and Pseudomonas aeruginosa. Ticarcillin is not active against methicillin-resistant Staphylococcus aureus (MRSA).

Inhibitor of protein synthesis; streptogramin

Gatifloxacin is an antibiotic, which is a synthetic fluoroquinolone with broad-spectrum antibacterial activity. Its source lies in its chemical synthesis, designed to inhibit bacterial enzymes necessary for DNA replication. The mode of action involves the inhibition of bacterial DNA gyrase and topoisomerase IV, which are critical enzymes for bacterial DNA replication, transcription, and repair. This dual inhibitory mechanism disrupts bacterial cell division and growth, leading to the eventual eradication of susceptible bacterial strains.

Pefloxacin mesylate is a fluoroquinolone antibiotic with action on bacterial DNA gyrase and topoisomerase IV and is used for treating bacterial infections, including urinary and respiratory tract infections.

Inhibits chaperone protein HSP90; anti-proliferative; antineoplastic

Cefsulodin sodium salt is a beta lactam antibiotic in the third-generation cephalosporin family that inhibits penicillin-binding proteins (PBPs) to disrupt bacterial cell wall synthesis.

Tilmicosin phosphate is a phosphate salt form of tilmicosin with similar action and applications as tilmicosin.

Validamycin A is an antibiotic and fungicide with action as a trehalase inhibitor, disrupting carbohydrate metabolism in fungi and is used for controlling fungal diseases like sheath blight in rice and damping-off in cucumbers.

Olaquindox is a quinoxaline derivative antibiotic with action on bacterial growth suppression in the gut and is used for promoting growth and controlling bacterial infections in livestock.

Azithromycin N-oxide is a macrolide antibiotic derivative and is used for research purposes. Its mode of action is similar to azithromycin.

Florfenicol is a broad-spectrum antibiotic used for the treatment of various bacteria infections. This drug is used in veterinary medicine and to treat animals with those infections. This drug works by inhibiting bacteria synthesis. It is a fluorinated synthetic analog of thiamphenicol.

Fluoroquinolone; gyrase inhibitor

Inhibitor of inosine monophosphate dehydrogenase; immunosuppressant

Nonactin is a macrotetrolide antibiotic with action as an ionophore for potassium and ammonium ions and is used for research on ion transport and bacterial inhibition.

Inhibitor of protein synthesis; lincosamide

Inhibitor of isoleucyl-tRNA synthetase; inhibitor of protein synthesis

Inhibitor of cell wall biogenesis; glycopeptide antibiotic

Tosufloxacin is a fluoroquinolone antibiotic that inhibits DNA gyrase and topoisomerase IV, which are enzymes that maintain the integrity of bacterial DNA. It binds to bacterial 16S ribosomal RNA and inhibits protein synthesis, leading to cell death by inhibiting the production of proteins vital for cell division. Tosufloxacin has been shown to be effective against a variety of bacterial infections.

A thiopeptide antibiotic produced by the bacterium Streptomyces actuosus. In addition, nosiheptide inhibits bacterial protein biosynthesis by acting during the elongation of the protein.

Gentamicin C2a sulfate is one epimeric form of the aminoglycoside antibiotic gentamicin (a.k.a. gentamycin). Gentamicin interferes with the correct protein production in bacterial cells, by binding to the 16s rRNA at the 30s ribosomal subunit. Gentamicin is a natural mixture of four congeners, one of which is gentamicin C2a. Gentamicin is active against clinically relevant aerobic gram-negative bacteria. Gentamicin C2a has been shown to be biodegradable in the environment, to some extent.

Inducer of DNA strand breaks; glycopeptide antibiotic, anti-neoplastic

Avibactam sodium is a β-lactamase inhibitor and is used for the treatment of complicated intra-abdominal and urinary tract infections in combination with ceftazidime. Its mode of action is similar to avibactam free acid

Netropsin dihydrochloride is a pyrrole-amidine antibiotic with action on AT-rich sequences of DNA to inhibit replication and is used for research on DNA-binding properties and antiviral activity.

2,4-Diacetylphloroglucinol is a natural phenol produced by certain bacteria, used for its biocontrol properties against plant pathogens.

Vancomycin hydrochloride is an antibiotic that is used against Gram-positive bacteria, including Staphylococcus aureus. It has been shown to inhibit the growth of bacteria by binding the D-alanyl-D-alanine moiety of the peptidoglycan cell wall precursor, inhibiting the peptidoglycan synthesis and disrupting its cross linking. It also inhibits particle formation when it reacts with human plasma, which can lead to hemolysis and hemagglutination. The absorption spectrum for vancomycin hydrochloride shows maxima at 230, 260, 290, and 320 nm, which are characteristic for this compound. Vancomycin has been used in several studies for treatment of methicillin-resistant Staphylococcus aureus infections.

Daptomycin is a cyclic lipopeptide that disrupts cell membrane potential and causes leakage from the cell. The antibacterial effects are limited to gram-positive bacteria since daptomycin can’t reach the outer membrane of gram-negative species. It is often used for infections cause by vancomycin-resistant enterococci and staphylococci.

Aureothricin is a dithiolopyrrolone antibiotic and is used for its antimicrobial properties. It inhibits transcription in bacteria, leading to growth inhibition

Nitrofurantoin is an antimicrobial agent, which is a synthetic chemical compound with bactericidal activity. Its source is synthetic, originating from the nitrofuran class of compounds. Nitrofurantoin's mode of action involves the inhibition of essential bacterial enzymes. It is reduced by bacterial flavoproteins to active intermediates, which subsequently alter or disrupt ribosomal proteins, DNA, and other vital macromolecules within bacterial cells, thereby inhibiting key metabolic processes.

Rifamycin O is a rifamycin antibiotic with action on bacterial RNA polymerase to inhibit transcription and is used for treating tuberculosis and travelers' diarrhea.

Sisomicin is an aminoglycoside antibiotic with action on bacterial protein synthesis inhibition and is used for treating severe bacterial infections resistant to other aminoglycosides.
