Antibióticos naturales y semisintéticos
Los antibióticos naturales y semisintéticos se caracterizan por estructuras químicas con anillos heterocíclicos y grupos funcionales activos que inhiben el crecimiento de microorganismos. Sus estructuras les permiten interactuar con los procesos vitales de las bacterias, lo que los hace útiles como tratamientos para infecciones bacterianas. Los antibióticos semisintéticos pueden ser modificados para mejorar el espectro de actividad o la resistencia a la degradación.
En CymitQuimica ofrecemos antibióticos naturales y semisintéticos de alta calidad para investigación en microbiología y desarrollo farmacéutico.

Producto descatalogadoDeoxynivalenol
CAS:Producto controlado<p>Applications Deoxynivalenol is a tricothecene mycotoxin and potent protein synthesis inhibitor. Deoxynivalenol exhibits cytotoxic activity in vivo via the ribotoxic stress response. Deoxynivalenol induces p38-mediated gene expression and apoptosis in leukocytes; activity results in systemic expression of interleukin-6 (IL-6) and other proinflammatory cytokines. Also induces migration of NF-κB into the nucleus.Environmental contaminants; Food contaminants<br> Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package<br>References Bae, et al.: Toxicol.

CAS:<p>Tacrolimus is a macrolide that is used as an immunosuppressive drug. It has been shown to bind to the FK-binding protein, which in turn inhibits calcineurin. This prevents the release of IL-2, TNF-α and other cytokines. The immunosuppressive effects of tacrolimus have been evaluated using analytical methods such as coefficients, affinity, and monitoring techniques such as immunoassays and agglutination. These techniques are used to evaluate the plasma concentration of tacrolimus. Tacrolimus also binds to proteins in the blood samples and can be detected by turbidimetric or electrochemiluminescence immunoassay reagents.</p>Fórmula:C43H67NO12Pureza:Min. 95%Peso molecular:789.99 g/mol15-Acetyl Deoxynivalenol (~90%)
