CAS :Actinomycin D is an antibiotic commonly used in chemotherapy for cancer treatment, such as sarcomas, and pediatric solid tumors, Wilms tumor, testicular cancer, and choriocarcinoma; it is generally not very useful in antibiotic therapy. It acts as a transcription inhibitor, binding to DNA duplexes at the transcription initiation complex and preventing RNA polymerase elongation.Formule :C62H86N12O16Degré de pureté :Min. 95%Couleur et forme :Red PowderMasse moléculaire :1,255.42 g/molC-390, Antibiotic for Culture Media Use Only
CAS :C-390 is an antibacterial agent. Selective isolation of Pseudomonas aeruginosa from other bacterial species when added to an agar medium.Formule :C29H27ClN2HClDegré de pureté :Min. 98.0 Area-%Masse moléculaire :490.05 g/molDihydrostreptomycin B
CAS :Dihydrostreptomycin B is an aminoglycoside antibiotic, which is derived from the bacterium Streptomyces griseus. This antibiotic operates by binding to the 30S subunit of the bacterial ribosome, leading to the inhibition of protein synthesis. The binding disrupts the decoding site, causing misreading of mRNA and ultimately resulting in bactericidal activity.Formule :C27H51N7O17Degré de pureté :Min. 95%Masse moléculaire :745.33414Colistin sulfate
CAS :Colistin is a narrow-spectrum antibiotic efficient mostly against gram-negative bacteria. Colistin interacts with the outer membrane of gram-negative bacteria and induces a transfer of divalent cations of calcium and magnesium from the negatively charged phosphate groups. This causes the disruption of the outer membrane and release of lipopolysaccharides. It is commonly used against Enterobacteriaceae and Aeromonas, and none-fermentative gram-negative bacteria as well as for carbapenem-resistant Acinetobacter strains.Formule :C53H102N16O17SDegré de pureté :Min. 77 Area-%Couleur et forme :White PowderMasse moléculaire :1,266.73 g/molDifloxacin
CAS :Difloxacin is a fluoroquinolone antibiotic, which is a synthetic compound derived from chemical synthesis methods. Its source involves complex organic chemistry that modifies the quinolone backbone to enhance its antibacterial properties. Difloxacin functions by inhibiting bacterial DNA gyrase and topoisomerase IV, which are critical enzymes involved in DNA replication, transcription, and repair.
