Antibactérien

Kikumycin A, an antibiotic produced by Streptomyces, exhibits antimicrobial activity against both Gram-positive and Gram-negative bacteria. Additionally, it demonstrates antitrichomonal activity with a minimum inhibitory concentration (MIC) of 25 μg/mL against Trichomonas foetus.

DNA Gyrase-IN-13 (compound 1b) is an inhibitor of DNA gyrase with bacteriostatic properties. It exhibits an IC50 of 1.81 μM against Staphylococcus aureus DNA gyrase.

Cefempidone (GR 50692) is a third-generation cephalosporin antibiotic. It exhibits antibacterial activity by inhibiting penicillin-binding proteins involved in the synthesis of bacterial cell walls.

Pks13-TE inhibitor 4 (compound 44) is a potent inhibitor from the thiazole series that effectively targets Pks13 to combat tuberculosis (TB) and addresses drug resistance.

7-APRA is a semisynthetic intermediate of the cephalosporin class of antibiotics. It exhibits antibacterial activity and is primarily used in the synthesis of other cephalosporin antibiotics, such as Cefaclor and Cefprozil.

QPX7728 bis-acetoxy methyl ester is an inhibitor of boronic acid β-lactamase.

Lapyrium chloride (Emcol E 607) is a broad-spectrum antibacterial agent that serves as a preservative and disinfectant.

Gougerotin is an inhibitor of protein synthesis.

<p>Mazethramycin is an antitumor antibiotic that exerts its effects by disrupting DNA replication and RNA synthesis within cells. It is utilized in cancer research.</p>

Apalcillin (PC-904) combined with Ro 48-1220 (a penicillin sulfone β-lactamase inhibitor) exhibits broad-spectrum activity against Gram-negative aerobic and anaerobic bacteria, excluding Klebsiella acid-producing strains. This combination shows strong efficacy against β-lactamase-producing Moraxella catarrhalis, Haemophilus influenzae, and Neisseria gonorrhoeae with an effective MIC of 11 μg/mL. Additionally, it inhibits Pseudomonas aeruginosa, Stenotrophomonas maltophilia, and Acinetobacter at low MICs (0.25 to 4 μg/mL). However, it has limited efficacy against oxacillin-resistant staphylococci and some Gram-positive bacteria. Apalcillin/Ro 48-1220's effectiveness against certain extended-spectrum β-lactamase-producing Escherichia coli is comparable to piperacillin/tazobactam, though it is less effective against SHV-type β-lactamases.

Antibiofilm agent-4 is a LasR inhibitor, demonstrating optimal antibiofilm and anti-QS (quorum sensing) properties.

Cetefloxacin (E 4868) is a broad-spectrum antibacterial antibiotic with a minimum inhibitory concentration (MIC) ranging from 0.007 to 8 µg/ml. In mice, cetefloxacin demonstrates favorable pharmacokinetic properties and provides protection against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus pneumoniae.

2'-Amino-2'-deoxyadenosine (9-(2-Amino-2-deoxypentofuranosyl)-9H-purin-6-amine) is a nucleoside antibiotic that effectively inhibits various Mycoplasma strains.

TBAJ-5307 is a broad-spectrum anti-non-tuberculous mycobacteria inhibitor that targets the FO-domain of the engine, preventing rotation and proton-translocation. TBAJ-5307 inhibits non-tuberculous mycobacteria in vitro and in vivo [1].

(E)-Cefodizime ((E)-THR-221) is an antibiotic that selectively binds to penicillin-binding proteins (PBPs), inhibiting bacterial cell wall synthesis, which results in its antibacterial activity. It holds potential for research into various bacterial infections, including the prevention of preoperative infections.

BDM91288, an orally active AcrB efflux pump inhibitor of pyridinium piperazine, enhances the in vivo efficacy of levofloxacin in treating Klebsiella pneumoniae pulmonary infection in mouse models [1].

Pyrromycin is a monosaccharide anthracycline which can be used to inhibit cellular RNA synthesis.

NDM-1 Inhibitor-5 (compound 57) exhibits strong inhibition of NDM-1, characterized by a K i of 2.5 μM. Additionally, it demonstrates synergistic antibacterial effects when combined with meropenem [1].

<p>Antibacterial agent 204 (Compd P2-56-3) enhances the activity of Rifampin (RIF) against Acinetobacter baumannii and Klebsiella pneumoniae by disrupting the outer membrane of A. baumannii. T [1].</p>

Pneumolysin-IN-1 (compound PB-3), characterized as a targeted small molecule inhibitor of Pneumolysin (PLY) with an IC50 value of 3.1 µM, acts as a pore-blocking agent and an anti-virulence factor. This compound is useful for researching infections caused by Streptococcus pneumoniae [1].
