  • Urea nitrate

    CAS:
    Urea nitrate is an analog of urea that has been shown to have potent anticancer activity. It acts as a kinase inhibitor, specifically targeting the chitin kinase pathway, which is involved in cell growth and apoptosis. Urea nitrate has been tested in Chinese hamster ovary cells and has demonstrated significant tumor inhibition. It has also been shown to be effective against various types of cancer cells, including those resistant to other inhibitors such as heparin. Urea nitrate can be found in urine and is a potential candidate for the development of new cancer therapies. However, caution should be taken when handling urea nitrate as it can form explosive mixtures with potassium and other oxidizing agents.

  • Valdecoxib dimer

    CAS:
    Valdecoxib dimer is a drug product that has been custom synthesized to meet the customer's requirements. It is an analytical standard and is available in high purity. Valdecoxib dimer has been shown to be metabolized through a number of metabolic transformations, including hydrolysis by esterases or glucuronidases, oxidation by cytochrome P450 enzymes, reduction by glutathione reductase, or conjugation with glucuronic acid. Valdecoxib dimer also specifically binds to markers expressed at high levels in Mycobacterium tuberculosis strains (e.g., ESX-1 secretion system protein) and inhibits cell growth in culture. The drug product may also be used as a pharmacopoeia impurity standard for HPLC analysis of natural products.
