Anti gram-positive negative bacteria agent 1 is an antibiotic conjugated with a synthetic MECAM-based siderophore, designed to combat both gram-positive and gram-negative bacteria.

Meropenem (SM 7338) is a broad-spectrum carbapenem antibiotic administered intravenously for severe bacterial infections caused by sensitive agents. It commonly causes mild, transient aminotransferase elevations and can rarely lead to clinically apparent cholestatic liver injury.

5-Bromo-5-nitro-1,3-dioxane (Bronidox) is an antimicrobial compound that inhibits bacterial enzyme activity.

Oxytetracycline Hydrochloride (Dalimycin) is a tetracycline derivative produced by Streptomyces rimosus with antimicrobial activity. It interferes with the binding of aminoacyl-tRNA to the mRNA-ribosome complex, resulting in preventing peptide elongation and inhibiting protein synthesis.

Bekanamycin (Kanamycin B) is an aminoglycoside antibiotic.

Cefodizime Sodium is a third generation cephalosporin antibiotic, has broad-spectrum activity

trans-Benzylideneacetone (Acetocinnamone) is used in various synthetic preparations.

Ceftobiprole medocaril (BAL5788), the parenteral prodrug of Ceftobiprole, is a broad-spectrum cephalosporin effective against Methicillin-resistant Staphylococcus aureus (MRSA).

Amikacin hydrate (BAY 41-6551 hydrate) is an aminoglycoside antibiotic with bacteriostatic activity used in studies of drug-resistant Mycobacterium tuberculosis infections and Gram-negative bacterial infections, and is commonly used in the clinic for urinary tract infections caused by E. coli.

(Z)-2-decenoic acid (cis-dec-2-enoic acid) is an unsaturated short-chain fatty acid secreted by Pseudomonas aeruginosa. It can induce a dispersion response in biofilms formed by gram-negative and gram-positive bacteria and can also inhibit biofilm development.

Ampicillin (Aminobenzylpenicillin) is a semi-synthetic penicillin belonging to the β-lactam group of antibiotics. Ampicillin has bactericidal activity against a wide range of Gram-positive and Gram-negative bacteria.

Lipopolysaccharides (LPS), derived from Escherichia coli O55:B5, are essential components of the outer membrane of Gram-negative bacteria. Composed of lipid A, a core oligosaccharide, and an O-specific polysaccharide, LPS exhibits strong immunogenicity. It activates immune cells via the TLR4 receptor, induces chemotactic cell migration and cytokine secretion, and helps maintain the integrity of the bacterial outer membrane, protecting against bile salts and lipid-based antibiotics. LPS is commonly used to establish inflammatory models, including arthritis, chronic obstructive pulmonary disease (COPD), acute respiratory distress syndrome (ARDS), and gastrointestinal disease models.

Nitrocefin is an antibiotic. It being sensitive to hydrolysis by all lactamases produced by gram-positive and gram-negative bacteria.

PNU288034, a potent oxazolidinone antibiotic, demonstrates antimicrobial activity for the prevention and treatment of Gram-negative infections.

Sapienic acid sodium is a fatty acid with variable antimicrobial activities against Gram-positive and Gram-negative bacteria found on the skin and in the oral cavity.

Tigemonam is a monobactam, a novel orally administered monobactam that protects against gram-negative aerobic bacterial pathogens and is at least as active against clinical isolates of Enterobacteriaceae as amitraz or carmonan (MIC90: 0.06-16 mg l). [3]

MAC13243 HCl, an inhibitor of LolA, a periplasmic chaperone that transports lipoproteins from the inner membrane to the outer membrane, is an antimicrobial agent with specificity and significant inhibitory effects on Gram-negative bacteria.

Sulopenem (CP-70429) is an orally active gastrointestinal-external cephalosporin antibiotic with broad-spectrum antibacterial activity. It inhibits Gram-positive and Gram-negative bacteria and can be used in bacterial infection research.

BB-78485 is a potent small molecule inhibitor of LpxC metalloenzymes with antibacterial activity. The IC50 value of BB-78485 against LpxC is 160 nM. BB-78485 can be used for the study of Gram-negative bacterial infections.

PF-04753299 is a potent and selective inhibitor of UDP-3-O-(R-3-hydroxymyristol)-N-acetylglucosamine deacetylase (LpxC), demonstrating bactericidal effects against gonococcal isolates and exhibiting inhibitory activity against E. coli, P. aeruginosa, and K. pneumoniae, with minimum inhibitory concentration (MIC) 90 values of 2 μg ml, 4 μg ml, and 16 μg ml, respectively. This compound is utilized in researching gram-negative bacterial infections [1].

Alalevonadifloxacin is a DNA gyrase and DNA topoisomerase inhibitor and a novel antibacterial compound of the quinolone class targeting MRSa. Alalevonadifloxacin is potentially useful in the treatment of bacterial Gram-positive, Gram-negative and anaerobic infections.

Sanfetrinem (GV104326) sodium is a novel orally available β-lactamase antibiotic that shows significant antibacterial activity against Gram-positive and Gram-negative bacteria and can be used in the study of bacterial infections.

Moiramide B is a potent acetyl coenzyme A carboxylase (ACC) inhibitor (IC50:6 nM) with antimicrobial activity, strongly inhibiting Gram-positive bacteria but weakly inhibiting Gram-negative bacteria.

Balofloxacin, a quinolone antibiotic, can inhibit the synthesis of bacterial DNA by interfering with the DNA gyrase.
