Standard farmaceutici
Gli standard farmaceutici sono un insieme completo di materiali di riferimento essenziali per garantire la sicurezza, l'efficacia e la qualità dei prodotti farmaceutici. Questa categoria include standard per ingredienti farmaceutici attivi (API), che sono i componenti principali responsabili degli effetti terapeutici. Inoltre, copre composti e metaboliti rilevanti sia per l'industria farmaceutica che veterinaria, fornendo punti di riferimento per la misurazione e l'analisi precisa di queste sostanze. Gli standard di controllo delle nitrosammine sono cruciali per rilevare e mitigare le nitrosammine potenzialmente dannose nelle formulazioni di farmaci. Gli standard di tossicologia aiutano a valutare la sicurezza e i potenziali effetti avversi dei composti farmaceutici. Inoltre, gli standard per attivatori e inibitori enzimatici sono vitali per la ricerca e lo sviluppo, consentendo studi precisi delle vie biochimiche e dei meccanismi d'azione dei farmaci. Questi standard farmaceutici sono strumenti indispensabili per la conformità normativa, il controllo di qualità e la ricerca, garantendo che i prodotti farmaceutici soddisfino rigorosi criteri di sicurezza ed efficacia.

Delta 5-avenasterol
CAS:Prodotto controllato<p>Delta 5-avenasterol is a fatty acid that is used as an anti-inflammatory. It has been shown to reduce inflammation in animals by inhibiting the production of arachidonic acid, which is a precursor of prostaglandins and leukotrienes. Delta 5-avenasterol also has antioxidant properties and can be used as an additive in animal feed to reduce oxidative stress. The most common form of delta 5-avenasterol found in plants is delta 5,6-avenasterol, but delta 5-avenasterol can also be found in soybean oil. Delta 5-avenasterol can be detected using various assays including the chromatographic assay with an ionization detector and a spectrophotometric assay with a UV detector.</p>Formula:C29H48OPurezza:Min. 95%Peso molecolare:412.69 g/molL-Methionine sulfoxide
CAS:<p>Methionine sulfoxide is a methionine that has been oxidized to methionine sulfoxide. Methionine sulfoxides are produced through protein oxidation, which is the chemical process of reacting with oxygen in the air or other compounds to form an organic peroxide and superoxide radical. Methionine sulfoxides are found in proteins and are formed as a result of oxidative stress on cells and tissues. The rate constant for the conversion of methionine to methionine sulfoxide is 0.01983 min-1 at pH 7, 25°C. There are two methods of detection: chemiluminescence method and chromatographic analysis. In addition, methionine sulfoxides have natural antioxidant properties that can be used to treat diseases such as Alzheimer's disease and Parkinson's disease, as well as cancer treatments. Methionine sulfoxides have been shown to have a significant effect on wild-type strains of bacteria, reducing their growth rates</p>Formula:C5H11NO3SPurezza:Min. 98 Area-%Colore e forma:White PowderPeso molecolare:165.21 g/molAcetyl-L-methionine sulfoxide

CAS:<p>Proflavine hemisulfate is an antibiotic that inhibits bacterial growth by binding to DNA and inhibiting DNA synthesis. It binds to the dinucleotide phosphate of the bacterial ribosome and changes the shape of the nucleotide, preventing attachment of amino acids to form proteins. Proflavine hemisulfate also has a strong affinity for nuclear dna and is bound to it in a form that inhibits replication. The free form of proflavine is converted into enzyme form by phosphorylation, which inhibits protein synthesis and cell division. Proflavine hemisulfate has been shown to inhibit multidrug efflux pumps in bacteria, leading to increased susceptibility of bacteria to antibiotics. In addition, proflavine hemisulfate possesses inhibitory properties against transfer reactions in cells. The method used for measuring proflavine hemisulfate activity is electrochemical impedance spectroscopy (EIS) on cell nuclei suspensions in a model system.</p>Formula:C13H11N3•(H2SO4)0•(H2O)xPurezza:Min. 95%Colore e forma:PowderPeso molecolare:258.29 g/molBoc-L-aspartic acid a-9-fluorenylmethyl ester
