Discontinued productProflavine hemisulfate
CAS: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.

Discontinued productNaphthalene
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.

Discontinued product4β-Hydroxy cholesterol 4-acetate
CAS:Controlled Product4b-Hydoxy cholesterol 4-acetate is a pleiotropic drug with a wide range of pharmacological activities. It is an inhibitor of the sirtuin family of proteins and may have anti-cancer effects. It has also been shown to be effective in the treatment of depression and myelodysplastic syndrome. The mechanism of action for this agent is not well understood, but it may be due to its ability to inhibit DNA methyltransferases, which would lead to a change in DNA methylation patterns. 4b-Hydroxy cholesterol 4-acetate has also been shown to decrease lipid levels in the blood and increase the activity of liver enzymes that metabolize fatty acids. This drug can also modify lamellar bodies and short-chain fatty acids by inhibiting the enzyme ATP citrate lyase, which catalyzes citrate cleavage into acetyl CoA and oxaloacetate.
