Target:
Rifaximin, a gastrointestinal-selective antibiotic, binds the β-subunit of bacterial DNA-dependent RNA polymerase, resulting in inhibition of bacterial RNA synthesis. Rifaximin susceptibility is higher against Gram-positive strains (MIC: 0.03-5 mg/ml) compared to Gram-negative bacteria (MIC: 8-50 mg/mL) .

Target:
Ribostamycin sulfate (Vistamycin sulfate) is a broad-spectrum aminoglycoside Antibiotic with bactericidal activity against Gram-positive cocci, Gram-negative cocci, bacilli, and drug-resistant strains. Ribostamycin sulfate also acts as an inhibitor of protein disulfide isomerase (PDI), with a binding constant KD of 319 μM for bovine PDI. Ribostamycin sulfate targets bacterial 16S ribosomal RNA and the 30S ribosomal subunit, causing translational misreading and thereby inhibiting bacterial protein synthesis. Ribostamycin sulfate disrupts the integrity of bacterial cell membranes, induces membrane pore formation, and leads to bacterial death. Ribostamycin sulfate can be used in studies related to bacterial infections .

AZD5099 is an orally effective pyrrole amide inhibitor and antibacterial agent. AZD5099 shows over 10000-fold higher selectivity for bacterial type II topoisomerases than for human topoisomerase IIα, with a IC50 value of 0.032 μmol/L against Staphylococcus aureus GyrB, a IC50 of 0.760 μmol/L against Escherichia coli GyrB, a IC50 of 73 nM against Escherichia coli ParE, a Kd of 83.8 nmol/L for Staphylococcus aureus GyrB, and a IC50 of >50 μM against human topoisomerase IIα. AZD5099 inhibits rat Mrp2 ATPase activity, competitively binds to the ATP-binding site of bacterial type II topoisomerases, blocks enzyme activity, reduces bacterial DNA and RNA synthesis, disrupts DNA replication and transcription processes, and induces mitochondrial toxicity. AZD5099 exhibits activity against Gram-positive bacteria, fastidious Gram-negative bacteria and drug-resistant strains, reduces bacterial loads in mouse infection models, and has a low spontaneous resistance frequency. AZD5099 can be used in studies related to infections caused by Gram-positive bacteria and fastidious Gram-negative bacteria, methicillin-resistant Staphylococcus aureus infections, Streptococcus pneumoniae pulmonary infections, as well as Staphylococcus aureus and Escherichia coli infections .
