Producto descatalogadoProflavine 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.

Producto descatalogadoTocopherols
CAS:Tocopherols are fat-soluble vitamins that belong to the family of tocopherols and tocotrienols. Tocopherols have a number of biochemical properties and antioxidant properties. These properties make them important for maintaining energy metabolism in cells, preventing oxidation of other molecules, and protecting the body from damage by reactive oxygen species. Tocopherols are found in a variety of biological sources such as plants, vegetable oils, nuts, grains, fruits and vegetables. The most common form is alpha-tocopherol (a-T). Other forms include gamma-tocopherol (g-T), delta-tocopherol (d-T), beta-tocopherol (b-T), and alpha-tocotrienol (a-TT). Biochemical assays for tocopherols and tocotrienols use p-hydroxybenzoic acid as an analytical reagent. This vitamin can be found in human serum or in
