(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.

Pureza:Min. 95%Proflavine 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.
