Antibacteriano

Colistin adjuvant-1, inhibits NF-κB (IC50: 0.209 μM), boosts mucin against gram-negative bacteria.

10(R)-hydroxy Stearic acid is a hydroxy fatty acid resulting from the hydroxylation of oleic acid, produced by gut microbiota.

Compound 11: Sulfonylurea derivative, antimicrobial, anticancer; MIC 0.039-0.156 mg/mL; A549 IC50: 19.7 μg/mL, PC3 IC50: 11.9 μg/mL.

KKL-40 is a small-molecule inhibitor that targets the trans-translation process, effectively suppressing methicillin-sensitive and resistant Staphylococcus aureus (S. aureus) and other Gram-positive pathogens, including vancomycin-resistant Enterococcus faecium, Bacillus subtilis, and Streptococcus pyogenes. It works in synergy with the human antimicrobial peptide LL-37 to inhibit S. aureus, but does not show synergistic effects with other antibiotics such as daptomycin, kanamycin, or erythromycin. KKL-40 inhibits trans-translation, an extreme form of recoding, while being non-toxic to HeLa cells.

L 689065 is a 5-lipoxygenase inhibitor.

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].

MraY-IN-3 (12a) is a potent inhibitor of the bacterial translocase MraY (IC50: 140 μM). 46 μg/ml).

Piperacillin hydrate is a semisynthetic broad-spectrum β-lactam antibiotic. It exhibits potent bactericidal activity against Gram-negative bacteria and some Gram-positive bacteria by targeting penicillin-binding proteins. Piperacillin hydrate is frequently combined with the β-lactamase inhibitor Tazobactam for enhanced efficacy.

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].

Levofloxacin mesylate is an orally active antibiotic effective against both Gram-positive and Gram-negative bacteria. It inhibits DNA gyrase and topoisomerase IV enzymes. Levofloxacin mesylate is employed in research related to chronic periodontitis, airway inflammation, and BK viremia. Additionally, it possesses anti-Orthopoxvirus activity.

MsbA-IN-2 is a potent inhibitor of the lipopolysaccharide transporter MsbA and is able to act on E. coli MsbA (IC50: 2 nM).

Vitamin K5 (hydrochloride), a naphthoquinone compound, exhibits trichomonacidal activity in vitro and can be utilized for anti-infection research [1].

NDM-1 inhibitor-7 (Compound A8) is an NDM-1 inhibitor with an IC50 of 10.284 μM. It restores the ability of meropenem (MEM) to penetrate the cell wall of Gram-negative bacteria and effectively reinstates MEM's antibacterial activity against NDM-1 positive Escherichia coli. Moreover, NDM-1 inhibitor-7 demonstrates significant efficacy in both Galleria mellonella and murine peritonitis infection models.

Antibacterial agent 113 targets multiple bacteria including P. aeruginosa and E. coli, showing efficacy at MIC 15625 μM.

G092 is a potent inhibitor of MsbA. MsbA is an ABC transporter protein. G092 has potential for antibacterial drug research.

LasR-IN-3 inhibits LasR in Pseudomonas, disrupting its dimer, causing loss of function.

Urease-IN-2 is a non-competitive inhibitor of urease (IC50: 0.94 μM, Ki: 1.6 μM) that non-competitively inhibits Jack bean urease (JBU).

4-Hexen-3-one inhibits the growth of H. pylori in the ATCC 43526 strain and TDR strain. Additionally, this compound suppresses urease activity.

Antitubercular agent-15 (5n): low toxicity, fights M. tuberculosis strains; MIC90 values range 0.73-18.8 μg/mL.
