Antibacterial agent 326 can be used in studies of bacterial infections, including those caused by Escherichia coli, Staphylococcus aureus, Enterococcus faecalis, Listeria spp., Bacillus subtilis, Serratia marcescens, Salmonella enteritidis and Acinetobacter calcoaceticus.

Nothramicin is an anthracycline antibiotic with anti-mycobacterial activity .

Lysine hydroxamate is an amino acid hydroxamate that inhibits the growth of Escherichia coli K-12. Of the other amino acid hydroxamates tested, only L-lysine hydroxamate reduced the growth rate. The inhibition of growth by L-serine hydroxamate could be rapidly reversed by adding L-serine to the bacterial culture or by removing the analog by filtration. This reversal was specific for L-serine. L-alanine, glycine, or adenine had no effect on the inhibited culture. There was no evidence for active transport of the analog.

N-Chlorosuccinimide (Succinchlorimide) is an oxidizing, hydrolyzable biochemical reagent with bactericidal and amoebicidal activities. N-Chlorosuccinimide can either form N-chloramines via concerted transfer of Cl⁺ or hydrolyze in aqueous solution to produce hypochlorous acid/hypochlorite. N-Chlorosuccinimide is effective in killing Shigella dysenteriae, Escherichia typhi and cysts of Entamoeba histolytica. N-Chlorosuccinimide can be formulated into fast-dispersing, fully soluble water purification tablets. N-Chlorosuccinimide is used in studies related to bacterial infections and parasitic infections.

Gatifloxacin (sesquihydrate) (Standard) is the analytical standard of Gatifloxacin (sesquihydrate). This product is intended for research and analytical applications. Gatifloxacin sesquihydrate (AM-1155; BMS-206584; PD135432) is a potent fluoroquinolone antibiotic with broad-spectrum antibacterial activity. Gatifloxacin sesquihydrate inhibits bacterial type II topoisomerases (IC50=13.8 μg/ml for S. aureus topoisomerase IV) and E. coli DNA gyrase (IC50 = 0.109 μg/ml). Gatifloxacin sesquihydrate can be used to treat bacterial conjunctivitis?in vivo.

GKL003 is a bacterial transcription inhibitor that targets the RNAP-σ interaction interface, with a K_i of 5.79 nM. GKL003 specifically binds to the RNAP β' clamp helix region at the σ^A factor binding site, blocks the formation of RNAP holoenzyme, and inhibits the formation of bacterial transcription initiation complexes. GKL003 inhibits the growth of both Gram-positive and Gram-negative bacterial cells, and also exhibits activity against drug-resistant strains.
