Tylosin phosphate
CAS :Produit contrôléTylosin phosphate is a macrolide antibiotic that has significant interactions with other drugs, such as erythromycin and estradiol benzoate. It is also an antimicrobial agent that can be used against human pathogens, such as methicillin-resistant Staphylococcus aureus (MRSA). Tylosin phosphate has been shown to have toxicological studies in animals and humans, which have shown it to be chemically stable. This drug binds to fatty acids in the bacterial cell membrane, inhibiting the production of fatty acid synthase, leading to death by starvation. Tylosin phosphate may also interfere with the synthesis of phospholipids in the bacterial cell membrane and inhibit protein synthesis by binding to ribosomes.Formule :C46H80NO21PDegré de pureté :Min. 95%Couleur et forme :SolidMasse moléculaire :1,014.1 g/mol(-)-B-Chlorodiisopinocampheylborane, 60% in Hexane, ca. 1.7mol/L
CAS :(-)-B-Chlorodiisopinocampheylborane is a carbonyl group that can be used for asymmetric synthesis. It was synthesized from the reaction of chlorodiisopinocampheylborane with butyllithium and allyl bromide, followed by aqueous workup. The enantiomers were separated through thin layer chromatography on silica gel plates with hexane as the eluent. The resolution of racemic latanoprost lactol was achieved in the same manner. (-)-B-Chlorodiisopinocampheylborane is also a diketone that can be prepared from para-chloroacetophenone and sodium hydroxide in ethanol. This diketone undergoes an intramolecular cyclization to produce noradrenaline (norepinephrine) and hydrochloric acid, which can then be converted into dioxolanes or other products.Formule :C20H34BClDegré de pureté :Min. 95%Couleur et forme :Clear LiquidMasse moléculaire :320.75 g/mol5a-Pregnane-3a,20a-diol
