CAS:Olsalazine sodium impurity C is a metabolite of olsalazine sodium. It is a natural product that can be custom synthesized for research and development purposes. Olsalazine sodium impurity C has been shown to have pharmacopoeia-grade purity and can be used as an analytical standard or an API impurity in drug products. The CAS number for this substance is 259151-72-9.Formula:C13H10N2O4Purity:Min. 95%Color and Shape:PowderMolecular weight:258.23 g/mol2-Acetamido-9-[[2-(acetyloxy)ethoxy]methyl]-6,9-dihydro-1H-purin-6-one
CAS:2-Acetamido-9-[2-(acetyloxy)ethoxy]methyl-6,9-dihydro-1H-purin-6-one (ademetionine) is a prodrug that is metabolized in the liver to form ademetionine. Ademetionine is a potent inhibitor of guanosine deaminase, which is an enzyme that breaks down guanosine into guanine and ammonia. Ademetionine has shown efficacy in cancer treatment and may also be used to treat tuberculosis. The metabolism of this drug takes place in the liver, where it undergoes oxidation by cytochrome P450 enzymes to form the active metabolite ademetionine. Metabolism of this drug can be inhibited by drugs such as trifluoromethanesulfonic acid (TFMS), which are used for the treatment of malaria. TFMS inhibits the formation of ademetionine but does not affect the formationFormula:C12H15N5O5Purity:Min. 95%Color and Shape:White PowderMolecular weight:309.28 g/molRoxithromycin

CAS:Gentamicin B1 is a gentamicin antibiotic that is used to treat skin cancer. It inhibits bacterial growth by binding to the 50S ribosomal subunit and blocking protein synthesis. Gentamicin B1 has shown clinical response in patients with wild-type strains of Streptococcus faecalis, but not in those with a mutant strain. The mechanism of action for this drug may involve its ability to inhibit epidermal growth factor (EGF) production. Gentamicin B1 also has been shown to inhibit the proliferation of human cancer cells and induce apoptosis in some tumor cells.Formula:C20H40N4O10Purity:Min. 95%Color and Shape:SolidMolecular weight:496.55 g/molTrospium Impurity 3 Iodide

CAS:Dibenzosuberone is a reactive, surfactant, and β-catenin inhibitor that has been shown to have anti-cancer activity against solid tumours. It is synthesized by the asymmetric synthesis of dibenzoyl-L-tartaric acid with sodium dodecylsulfate in the presence of light. The substrate film is used to increase the rate of reactivity. Dibenzosuberone inhibits the growth of cancer cells by inhibiting cyclic peptide synthesis and blocking light emission from these cells. Dibenzosuberone also has an effect on cell migration and proliferation through its interactions with β-catenin. Dibenzosuberone hydrolyzes in aqueous solution to form benzene, which can be removed by adding hydrochloric acid or hydrogen bonding with anhydrous sodium.Formula:C15H12OPurity:Min. 95%Color and Shape:Solidified MassMolecular weight:208.26 g/molIndacaterol Impurity 6 HCl
