Standard farmaceutici

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.

  • 3,3'-Diheptyloxacarbocyanine iodide

    CAS:

    3,3'-Diheptyloxacarbocyanineiodide (DHCI) is a fluorescent probe that is used in the treatment of solid tumours. It is taken up by tumor cells and causes them to fluoresce, which can be seen under a microscope. DHCI has been shown to be effective against hypoxic tumours and tumors with low oxygen levels due to its ability to penetrate tumor cells and deliver oxygen. The uptake of DHCI by cancer cells is also dependent on the permeability of the blood vessels present in the tumor. This drug has been shown to have a large therapeutic window for treatment of solid tumours.

  • N-a-t-Boc-N-g-trityl-L-asparagine

    CAS:

    N-a-t-Boc-N-g-trityl-L-asparagine is a recombinant human protein that has been synthesized in E. coli. It is a peptide with 17β-estradiol at its C terminus, and it binds to the oestrogen receptor α (ERα) via hydrogen bonding interactions. The linker between the asparagine and estradiol is a Boc group that can be removed by protease activity, revealing the active form of 17β-estradiol. ERα ligates to N-a-t-Boc-N-g-trityl L asparagine with high affinity, and this interaction is reversible. The linker also contains a functional group for surface attachment, which may be used to attach this peptide to a solid support or tissue culture substrate for use in cell cultures.

  • Sodium sarcosinate - ca. 40% in water

    CAS:

    Sodium sarcosine is a salt of sarcosine with sodium. It has an average molecular weight of 255 and is soluble in water. Sodium sarcosine is used as a biological sample for non-steroidal anti-inflammatory drugs (NSAIDs) in the study of their inhibitory properties against mammalian DNA polymerase. NSAIDs are also used to treat inflammation, pain, and fever by inhibiting prostaglandin synthesis. The rate constant for the reaction between NSAIDs and DNA polymerase was found to be 1.6x10^-4 M^-1s^-1 at 25°C, which is close to the Km value for the reaction. This finding indicates that NSAIDs may be competitive inhibitors of the enzyme, although further experiments are needed to confirm this hypothesis. Using electrochemical impedance spectroscopy, it was found that NSAIDs have a higher affinity for divalent cations than monovalent cations, suggesting that they bind to a site on the
