Antibiotiques Naturels et Semi-Synthétiques
Les antibiotiques naturels et semi-synthétiques se caractérisent par des structures chimiques comprenant des cycles hétérocycliques et des groupes fonctionnels actifs qui inhibent la croissance des micro-organismes. Leurs structures leur permettent d’interagir avec les processus vitaux des bactéries, ce qui les rend utiles pour le traitement des infections bactériennes. Les antibiotiques semi-synthétiques peuvent être modifiés afin d’améliorer leur spectre d’activité ou leur résistance à la dégradation.
Chez CymitQuimica, nous proposons des antibiotiques naturels et semi-synthétiques de haute qualité pour la recherche en microbiologie et le développement pharmaceutique.

<p>Micafungin impurity B is a natural metabolite of micafungin. It is a synthetic impurity standard used in HPLC analysis. Micafungin impurity B has been shown to be the primary metabolite of micafungin in humans and is excreted in the urine and feces. Metabolism studies have shown that it may be formed by oxidation of the hydroxyl group at position C-3 or by hydrolysis of the amide bond between carbons C-4 and C-5.</p>Degré de pureté :Min. 95%Desmethyl tacrolimus
CAS :<p>Tacrolimus is a macrolide antibiotic that binds to the calcineurin receptor and inhibits the production of cytokines. It is used to treat certain types of autoimmunity and hyperproliferation in patients with cancer, organ transplant recipients, and those who have undergone radiation therapy. The drug is available in two forms: tacrolimus (the natural form) and desmethyl tacrolimus (a metabolite). Desmethyl tacrolimus is produced by microbial transformation, which converts the natural form into a more water-soluble derivative. This conversion can be prevented by adding additives such as proton pump inhibitors or pde5 inhibitors. Symptoms of tacrolimus include hyperglycemia, hyperlipidemia, gastrointestinal disturbances, headache, fever, skin rash, diarrhea, and anemia. Tacrolimus has been shown to inhibit the activity of fk506-binding proteins in vitro and in vivo through competitive inhibition.</p>Formule :C43H67NO12Degré de pureté :Min. 90 Area-%Couleur et forme :White PowderMasse moléculaire :789.99 g/molIvermectin 8α-Hydroperoxide (>85%)
