Cefazolin, Antibiotic for Culture Media Use Only
CAS :Cefazolin is a semi-synthetic, non-beta lactam antibiotic used for the treatment of a variety of bacterial infections. It inhibits cell wall synthesis by binding to one or more of penicillin-binding proteins (PBPs), which are bacterial transpeptidases that crosslink peptidoglycan strands. Cefazolin binds to PBPs present on the surface of all Gram-negative bacteria as well as many Gram-positive bacteria. It is not effective against methicillin-resistant staphylococcus and MRSA unless combined with another antibiotic such as vancomycin or flucloxacillin. A study showed that cefazolin can decrease inflammation and tumor necrosis factor-beta levels in pregnant women with systemic inflammatory disease. It has been tested in the development of an anti-inflammatory agent for use in patients with autoimmune diseases such as rheumatoid arthritis and lupus erythe.Formule :C14H14N8O4S3Masse moléculaire :454.51 g/molCyclosporin L
CAS :Cyclosporin L is an immunosuppressive agent, which is a cyclic polypeptide derived from the soil fungus Tolypocladium inflatum. It primarily functions by inhibiting the activity of calcineurin, a key phosphatase involved in the activation of T-cells. This inhibition prevents the transcription of interleukin-2 and other cytokines critical for T-cell proliferation.

CAS :Deacetylanisomycin is a bacterial metabolite, which is derived from the soil bacterium Streptomyces griseolus. It acts as an inhibitor of protein synthesis by binding to the 60S ribosomal subunit, thus interfering with peptide bond formation during translation. This mode of action is key to its effectiveness in studying the mechanisms of protein synthesis interruption.Formule :C12H17NO3Degré de pureté :Min. 95%Couleur et forme :White To Off-White SolidMasse moléculaire :223.27 g/molOligomycin B
CAS :Oligomycin B is an antibiotic compound, which is derived from Streptomyces species. It is an inhibitor of the mitochondrial ATP synthase complex, specifically targeting the F₀ subunit of ATP synthase. This action obstructs the proton channel, preventing the flow of protons across the mitochondrial membrane. As a result, Oligomycin B effectively halts ATP synthesis by oxidative phosphorylation, which is crucial for the survival of aerobic organisms.
