Desfuroyl ceftiofur sodium is a veterinary cephalosporin antibiotic, which is derived from cephalosporin C, a beta-lactam antibiotic produced by the fungus Cephalosporium acremonium. Its mode of action involves the inhibition of bacterial cell wall synthesis by binding to and inactivating penicillin-binding proteins (PBPs). This prevents the cross-linking of peptidoglycan layers, leading to cell lysis and bacterial death, particularly effective against Gram-negative and some Gram-positive bacteria.

Ribavirin is a guanosine nucleoside analog with broad-spectrum antiviral properties. Ribavirin gets phosphorylated to ribavirin triphosphate in cells and competes with natural nucleotides for incorporation in a nascent RNA chain, thus interfering with RNA synthesis by inhibiting viral RNA polymerases. Ribavirin is also an inhibitor of inosinate dehydrogenase (IMP), which is involved in the biosynthesis of GTP.

Amphotericin B is a macrocycle antibiotic with very potent antifungal effects and resistance very rarely occurs. Amphotericin B is a polyene antifungal that binds to fungal cell membrane, i.e., ergosterol disrupts the membrane permeability leading to leakage of intracellular components. It is often used as an alternative therapy for leishmaniasis and to treat severe mycoses including: systemic Candida, Cryptococcus, blastomycosis, and histoplasmosis.

Ceftaroline fosamil is an antibacterial agent used to treat various bacterial infections such as pneumonia. Ceftaroline fosamil binds to the ribosomal RNA of bacteria, preventing the formation of proteins necessary for cell division. Ceftaroline fosamil has been shown to be highly active against Mycobacterium tuberculosis, Mycobacterium avium complex, and fungi such as Candida species.

Ceftazidime is a broad-spectrum beta-lactam antibiotic that inhibits bacterial growth by inhibiting penicillin-binding proteins (PBPs). It is used to treat many bacteria infections including pneumonia and septicaemia. It has shown to be effective against some treatment-resistant bacteria such as Pseudomonas aeruginosa.

Ninhydrin is a chemical reagent, which is a saturated triketone compound utilized extensively in biochemical analysis and forensic science. It is synthesized through the dehydrogenation of related organic compounds and is often encountered in its crystalline form.

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.
