Antibióticos Naturais e Semissintéticos

Antibióticos Naturais e Semissintéticos

Os antibióticos naturais e semissintéticos são caracterizados por estruturas químicas com anéis heterocíclicos e grupos funcionais ativos que inibem o crescimento de microrganismos. Suas estruturas permitem-lhes interagir com os processos vitais das bactérias, tornando-os úteis para o tratamento de infecções bacterianas. Os antibióticos semissintéticos podem ser modificados para melhorar o espectro de atividade ou a resistência à degradação. Na CymitQuimica, oferecemos antibióticos naturais e semissintéticos de alta qualidade para pesquisa em microbiologia e desenvolvimento farmacêutico.

  • 15-O-Demethyl Tacrolimus

    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>
