Sarafloxacin hydrochloride is a quinolone antibiotic drug.Target: Antibacterialsarafloxacin hydrochloride is a fluoroquinolone antibiotic registered for use against poultry diseases. Sarafloxacin treatment demonstrated mineralization to 14CO2 amounting to 0.58%, 0.49%, and 0.57% in loam, silt loam, and sandy loam soils, respectively, at the termination of the test [1]. The inhibitory level of sarafloxacin for the tested bacteria was strain dependent. It appeared that in broth culture Escherichia coli isolates were sensitive to sarafloxacin concentrations 5-fold lower than the concentrations present in the simulated gut model, suggesting that sarafloxacin may be partially unavailable due to absorption to organic matter in the model [2]. Administering Sarafloxacin hydrochloride in the feed for 5 d at a dose of 10 or 12.5 mg/kg of fish proved efficacious in treating channel catfish infected with E. ictaluri in all three field trials. Average survival of the nonmedicated group was 43% in trial 1, 11°% in trial 2, and 59% in trial 3. Survival of the corresponding Sarafloxacin hydrochloride-medicated groups averaged 68, 48, and 73%. Antibiotic therapy with Sarafloxacin hydrochloride significantly (P < 0.05) improved survival in all trials [3].
Ethionamide(2-ethylthioisonicotinamide) is an antibiotic used in the treatment of tuberculosis.Target: AntibacterialEthionamide is a second-line antitubercular agent that inhibits mycolic acid synthesis. It also may be used for treatment of leprosy. Ethionamide is a prodrug. It is activated by the enzyme EthA, a mono-oxygenase in Mycobacterium tuberculosis, and binds NAD+ to form an adduct which inhibits InhA in the same way as isoniazid. Expression of the ethA gene is controlled by EthR, a transcriptional repressor. It is understood that improving ethA expression will increase the efficacy of ethionamide and so EthR inhibitors are of great interest to co-drug developers. The action may be through disruption of mycolic acid [1, 2].
Rifalazil (KRM-1648; ABI-1648), a rifamycin derivative, inhibits the bacterial DNA-dependent RNA polymerase and kills bacterial cells by blocking off the β-subunit in RNA polymerase[1].

Chloramphenicol is a broad-spectrum antibiotic.Target: AntibacterialChloramphenicol is a bacteriostatic drug that stops bacterial growth by inhibiting protein synthesis. Chloramphenicol prevents protein chain elongation by inhibiting the peptidyl transferase activity of the bacterial ribosome. It specifically binds to A2451 and A2452 residues in the 23S rRNA of the 50S ribosomal subunit, preventing peptide bond formation. While chloramphenicol and the macrolide class of antibiotics both interact with ribosomes, chloramphenicol is not a macrolide. It directly interferes with substrate binding, whereas macrolides sterically block the progression of the growing peptide [1, 2].
