Étalons pharmaceutiques
Les standards pharmaceutiques sont un ensemble complet de matériaux de référence essentiels pour garantir la sécurité, l'efficacité et la qualité des produits pharmaceutiques. Cette catégorie comprend des standards pour les ingrédients pharmaceutiques actifs (APIs), qui sont les composants principaux responsables des effets thérapeutiques. De plus, elle couvre les composés et métabolites pertinents pour les industries pharmaceutique et vétérinaire, fournissant des points de référence pour la mesure et l'analyse précises de ces substances. Les standards de contrôle des nitrosamines sont cruciaux pour détecter et atténuer les nitrosamines potentiellement nocives dans les formulations médicamenteuses. Les standards de toxicologie aident à évaluer la sécurité et les effets indésirables potentiels des composés pharmaceutiques. En outre, les standards pour les activateurs et les inhibiteurs enzymatiques sont essentiels pour la recherche et le développement, permettant des études précises des voies biochimiques et des mécanismes des médicaments. Ces standards pharmaceutiques sont des outils indispensables pour la conformité réglementaire, le contrôle de qualité et la recherche, garantissant que les produits pharmaceutiques répondent à des critères stricts de sécurité et d'efficacité.

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>Formule :C10H9NO4Degré de pureté :Min. 97.5 Area-%Couleur et forme :Yellow PowderMasse moléculaire :207.18 g/molGuanosine-5'-triphosphate Disodium Salt (~85%)

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>Formule :C10H8Degré de pureté :Min. 95%Masse moléculaire :128.17 g/mol7b-Hydroxy cholesterol 3b-acetate
CAS :Produit contrôlé<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>Formule :C29H48O3Degré de pureté :Min. 95%Masse moléculaire :444.69 g/molValeric acid
CAS :<p>Valeric acid is a fatty acid that is used in the manufacture of polymers. Valeric acid can be synthesized from caproic acid, which is found in palm oil and coconut oil. Valeric acid has been shown to inhibit the activity of nicotinic acetylcholine receptors at low concentrations and to have an inhibitory effect on the ryanodine receptor at high concentrations. Valeric acid also has a matrix effect on analytical methods such as gas-liquid chromatography, which has been modeled using polymer compositions.</p>Formule :C5H10O2Degré de pureté :Min. 95%Masse moléculaire :102.13 g/mol3-Iodo-L-tyrosine
