CAS:Ceftizoxime alapivoxil is a prodrug antibiotic, which is derived from ceftizoxime, a third-generation cephalosporin. This semi-synthetic source enables the compound to effectively combat a wide range of bacterial infections by improving oral bioavailability compared to its parent compound. Once administered, ceftizoxime alapivoxil is metabolized in the body to release ceftizoxime, which exerts its antibacterial activity by binding to penicillin-binding proteins (PBPs) on bacterial cell walls. This binding action inhibits the transpeptidation step critical for cell wall synthesis, leading to cell lysis and bacterial death.Pureza:Min. 95%Narasin
CAS:<p>Narasin is an ionophore antibiotic, which is a fermentation product derived from certain strains of the bacterium *Streptomyces aureofaciens*. It functions by disrupting the ion gradients across cell membranes, specifically facilitating the transport of sodium and potassium ions. This action interferes with the energy metabolism of certain pathogenic microorganisms, rendering them unable to proliferate effectively.</p>Fórmula:C43H72O11Pureza:Min. 95%Peso molecular:765.03 g/molNeomycin B
CAS:<p>Neomycin B is an aminoglycoside antibiotic, which is derived from the bacterium *Streptomyces fradiae*. It exerts its antibacterial effects by binding to the 30S subunit of bacterial ribosomes, leading to the inhibition of protein synthesis. This binding disrupts the translation process, thereby preventing the growth and proliferation of bacteria. Neomycin B is effective against a wide range of Gram-negative and some Gram-positive bacteria, making it a valuable tool in both medical and research settings.</p>Fórmula:C23H46N6O13Pureza:Min. 95%Peso molecular:614.64 g/molClindamycin

CAS:<p>Sulbenicillin is a semi-synthetic penicillin antibiotic, which is derived from 6-aminopenicillanic acid, a natural precursor in the biosynthesis of penicillins. With its beta-lactam structure, Sulbenicillin disrupts bacterial cell wall synthesis by inhibiting penicillin-binding proteins, which are essential enzymes in the cross-linking of peptidoglycan layers. This disruption compromises the structural integrity of the bacterial cell wall, resulting in cell lysis and death, particularly in Gram-negative bacteria.</p>Fórmula:C16H18N2O7S2Pureza:Min. 95%Peso molecular:414.46 g/molVancomycin CDP-1
