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.

CAS:<p>1-(3,4-Methylenedioxyphenyl) 2-nitropropene (1-MPNP) is a phosphatase inhibitor that is active against gram-negative bacteria by inhibiting enterotoxins and chlamydia. 1-MPNP inhibits the activity of tyrosine phosphatases, which are enzymes that play a major role in bacterial virulence. 1-MPNP competitively inhibits the activity of tyrosine phosphatases and prevents them from catalyzing the hydrolysis of polyphosphate substrates. This inhibition leads to an accumulation of polyphosphates in the bacterial cell membrane, which disrupts its permeability and leads to cell death.</p>Formula:C10H9NO4Purezza:Min. 97.5 Area-%Colore e forma:Yellow PowderPeso molecolare:207.18 g/molL-Methionine
CAS:<p>L-Methionine is a non-essential amino acid that belongs to the group of essential amino acids. It is a major constituent of proteins and is used in the metabolism of lipids, carbohydrates, and nucleic acids.

CAS:Prodotto controllato<p>7b-Hydroxy cholesterol 3b-acetate is an allylic compound that is catalyzed by molybdenum, which eliminates the acetyl group at position 7 to form a double bond with the 3-position. The reaction temperature of 7b-hydroxy cholesterol 3b-acetate can be increased to high temperatures (i.e., >100°C) for the elimination process, and allylic acetates are obtained as products. The reaction starts with the addition of hexacarbonyl, which leads to a diene intermediate. This is then eliminated by adding acetamide in presence of high concentration of acetic acid and catalytic amounts of molybdenum. The low yield and efficiency, however, are major drawbacks of this process.</p>Formula:C29H48O3Purezza:Min. 95%Peso molecolare:444.69 g/molRef: 3D-FH23948

CAS:<p>Naphthalene is a chemical that is used for wastewater treatment and as a pesticide. It is also used in the manufacturing of polymers, resins, and plastics. Naphthalene has antimicrobial properties due to its hydrophobic effect. Naphthalene's antimicrobial activity is based on its ability to react with the skeleton of bacterial cells and disrupt the integrity of their outer membrane. Naphthalene also interacts with proteins and DNA, causing cell death. The molecular mechanisms of naphthalene's antibacterial activity are not well understood but have been studied using Hl-60 cells, which are immortalized human monocytic leukemia cells. This study showed that naphthalene affects the cell cycle by inhibiting protein synthesis in bacteria through binding to ribosomes or by disrupting the dna replication process.</p>Formula:C10H8Purezza:Min. 95%Peso molecolare:128.17 g/mol6-Methoxy-1,2,3,4-tetrahydronaphthalen-2-ylamine
