Cefoxitin sodium salt, Antibiotic for Culture Media Use Only
CAS:Cefoxitin sodium salt is a cephamycin-type antibiotic, which is a semi-synthetic derivative of cephalosporin. As a beta-lactam antibiotic, it is derived from the fermentation of *Streptomyces lactamdurans* and chemically modified to enhance stability against certain bacterial beta-lactamases. Its primary mode of action involves inhibiting bacterial cell wall synthesis by binding to penicillin-binding proteins, disrupting the transpeptidation or cross-linking of peptidoglycan layers. This action effectively prevents the bacteria from maintaining cell wall integrity, leading to cell lysis.Fórmula:C16H16N3NaO7S2Pureza:Min. 98.0 Area-%Peso molecular:449.43 g/molRef: 3D-C-2480

CAS:Chlorotetracycline monohydrochloride is an antibiotic compound specifically designed for culture media use. It is derived from a naturally occurring tetracycline produced by the bacterium *Streptomyces aureofaciens*. As a broad-spectrum antibiotic, chlorotetracycline functions by inhibiting protein synthesis in susceptible bacteria. It binds to the 30S subunit of the bacterial ribosome, blocking the attachment of aminoacyl-tRNA to the ribosomal acceptor site, which effectively halts translational elongation.Fórmula:C22H24Cl2N2O8Pureza:(Chlortetracycline Hcl) Min. 89.5%Forma y color:Yellow PowderPeso molecular:515.34 g/molEnduracidin - ca. 8%

CAS:Fostriecin is a potent anticancer agent, which is a natural product isolated from the bacterium Streptomyces pulveraceus. It acts primarily as an inhibitor of protein phosphatases, particularly protein phosphatase 2A (PP2A) and protein phosphatase 4 (PP4), functioning by blocking their catalytic activity. This inhibition disrupts cell cycle regulation, leading to apoptosis in cancer cells.Fórmula:C19H27O9PPureza:Min. 95%Peso molecular:403.4 g/molKanamycin sulfate
