:Ascomycine
Description :
Ascomycine, avec le numéro CAS 104987-12-4, est un antibiotique macrolide dérivé de la fermentation de certaines espèces de champignons, en particulier celles du genre *Aspergillus*. Il présente un large spectre d'activité antifongique, ciblant principalement diverses souches de champignons, y compris *Candida* et *Aspergillus*. Ascomycine agit en inhibant la synthèse des parois cellulaires fongiques, empêchant ainsi la croissance et la réplication. En plus de ses propriétés antifongiques, il a montré des effets immunosuppresseurs, ce qui le rend intéressant dans le contexte des transplantations d'organes et des maladies auto-immunes. Le composé se caractérise par sa structure macrolide complexe, qui comprend un grand anneau lactone et plusieurs groupes fonctionnels qui contribuent à son activité biologique. Ascomycine est généralement administré dans un cadre clinique sous stricte supervision médicale en raison de ses effets puissants et de ses effets secondaires potentiels. Sa solubilité et sa stabilité peuvent varier en fonction de la formulation, influençant sa pharmacocinétique et son efficacité thérapeutique.

CAS :<p>Ascomycin is an immunosuppressive macrolide, which is a product derived from the fermentation of the bacterium *Streptomyces hygroscopicus*. Its mode of action involves binding to the intracellular protein FK506-binding protein (FKBP), inhibiting the calcium-dependent signal transduction pathway that is crucial for T-cell activation. This interference with the immune response is achieved through the inhibition of calcineurin, thus preventing the dephosphorylation and nuclear translocation of nuclear factor of activated T-cells (NF-AT), a necessary step in the activation of genes required for T-cell proliferation.</p>Formule :C43H69NO12Degré de pureté :Min. 95%Masse moléculaire :792.01 g/molAscomycin
CAS :<p>Ascomycin is an immunosuppressant macrolide lactone, which is derived from the soil bacterium *Streptomyces hygroscopicus*. It functions primarily by inhibiting the T-cell activation pathway. The mechanism involves binding to the immunophilin FKBP-12, forming a complex that inhibits the calcium-dependent phosphatase, calcineurin. This inhibition prevents the dephosphorylation and subsequent translocation of nuclear factor of activated T cells (NFAT), which is crucial for the transcription of interleukin-2 and other cytokines. Consequently, this suppresses the activation and proliferation of T-cells, which are essential components of the adaptive immune response.</p>Formule :C43H69NO12Degré de pureté :Min. 95%Masse moléculaire :792.01 g/mol
