(S)-3',5'-Bis(trifluoromethyl)-1-phenethanol
CAS:(S)-3',5'-Bis(trifluoromethyl)-1-phenethanol is a choline derivative that is used in the treatment of liver cancer. It has been shown to increase the permeability of cell membranes and to suppress the growth of tumor cells by inhibiting protein synthesis. (S)-3',5'-Bis(trifluoromethyl)-1-phenethanol can be used as a surfactant and a hydrophobic solvent for optimization of reaction parameters. This chemical also has been shown to be active against Gram-positive bacteria such as Staphylococcus aureus and Enterococcus faecalis, but not against Gram-negative bacteria such as Escherichia coli or Pseudomonas aeruginosa. The mechanism of this effect is mediated by chloride ions that act as bioreductive agents on cellular membranes, leading to increased permeability and cell death.

Prodotto fuori produzione(±)-3-Methyl-2-oxovaleric acid
CAS:(±)-3-Methyl-2-oxovaleric acid is a fatty acid that is found in the mitochondria of liver cells and other tissues. It is an intermediate in the citric acid cycle and can be converted into acetyl-CoA, which is used for energy production. (±)-3-Methyl-2-oxovaleric acid has been shown to cause necrotic cell death when it binds to the mitochondrial membrane potential and causes a loss of ATP production. This results in a lack of energy for the cell, leading to cell death. (±)-3-Methyl-2-oxovaleric acid has also been shown to inhibit protein synthesis by decreasing uptake and increasing creatine kinase activity. This inhibition leads to decreased body formation and tissue culture growth in vitro. In vivo, (±)-3-Methyl-2-oxovaleric acid causes primary sclerosing cholangitis, a disease characterized by inflammation of bile ducts that

CAS:Prodotto controllatoa,O-Dimethyl serotonin is a monoamine compound that is synthesized by the enzymatic decarboxylation of 5-hydroxytryptophan. It has been shown to increase dopamine levels and inhibit the enzyme activity of serotonin in mice. This drug also binds to 5-ht2 receptors and induces the release of serotonin from nerve cells. A linear calibration curve was obtained using bufotenin as a standard. This drug has been used in analytical toxicology for determining the uptake of serotonin into human lung tissue and its effect on 5-ht1a receptors. In addition, a study was conducted with perennial ryegrass to determine whether this drug inhibits plant toxin synthesis. The results showed that it did not have an inhibitory effect on plant toxins and may even promote their synthesis.
Formula:C12H16N2OPurezza:Min. 95%Peso molecolare:204.27 g/molProflavine 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.
