Natural and semi-synthetic antibiotics
Natural and semisynthetic antibiotics are characterised by chemical structures with heterocyclic rings and active functional groups that inhibit the growth of microorganisms. Their structures allow them to interact with vital bacterial processes, making them useful treatments for bacterial infections. Semisynthetic antibiotics can be modified to enhance their spectrum of activity or resistance to degradation.
At CymitQuimica, we offer high-quality natural and semisynthetic antibiotics for research in microbiology and pharmaceutical development.

CAS:Controlled Product<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.

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>Formula:C43H67NO12Purity:Min. 95%Molecular weight:789.99 g/mol15-Acetyl Deoxynivalenol (~90%)
