Aclacinomycin HCl
CAS:<p>Aclacinomycin HCl is a cytotoxic antibiotic that inhibits the growth of tumor cells. It has been shown to induce apoptosis in human leukemia cells by altering the transmembrane potential and inhibiting cell proliferation. Aclacinomycin HCl also induces DNA damage response, which leads to caspase activities and cell death. This drug is highly selective for tumor cells, with no effect on normal cells. It has been shown to be effective against primary liver cancer in animal models, as well as developmental disorders such as autism spectrum disorder (ASD).</p>Formula:C42H53NO15·HClPurezza:Min. 95%Colore e forma:Orange PowderPeso molecolare:848.33 g/molGentamicin C2 pentaacetate (2 : 1 Mixture of C2 and C2a)

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.Purezza:Min. 95%Narasin
CAS:<p>Narasin is an ionophore antibiotic, which is a fermentation product derived from certain strains of the bacterium *Streptomyces aureofaciens*.
