CAS :2-Bromo-3'-hydroxyacetophenone is a molecule that has been shown to be cytotoxic and effective in inhibiting the growth of cancer cells. 2-Bromo-3'-hydroxyacetophenone inhibits the production of kynurenine, an amino acid that is used in the production of proteins, by competitively binding to the enzyme IDO1. This binding prevents the conversion of tryptophan into kynurenine, leading to cell death. The cytotoxicity of 2-bromo-3'-hydroxyacetophenone was also confirmed by testing its ability to inhibit cellular interaction with human erythrocytes (blood cells) and by measuring its effects on crystallography efficiency.
Formule :C8H7BrO2Degré de pureté :Min. 95%Couleur et forme :Slightly Yellow PowderMasse moléculaire :215.04 g/molNaphthalene
CAS :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.
