  • Moclobemide N-oxide

    CAS:
    Moclobemide N-oxide is a metabolite of moclobemide, an antidepressant drug. It is a white to off-white crystalline powder with a molecular formula of C14H14N2O4 and a molecular weight of 237.3. Moclobemide N-oxide is used in the treatment of depression, but it has not been approved for clinical use in the United States. Moclobemide N-oxide is extensively metabolized by cytochrome P450 enzymes, which may lead to variations in its activity among patients. The following are examples of high quality descriptions: Rifapentine is an anti-tuberculosis drug that belongs to the class of rifamycins. It is the most active of the rifamycins for the treatment of tuberculosis. Rifapentine inhibits bacterial growth by binding to DNA-dependent RNA polymerase, thereby preventing transcription and replication. The high frequency

  • Rivaroxaban

    CAS:
    Rivaroxaban is an analog of the kinase inhibitor which has been shown to have potent anticancer activity. It works by inhibiting kinases that are involved in cancer cell growth and survival. Rivaroxaban induces apoptosis in human and Chinese hamster ovary cells, leading to tumor cell death. This drug also inhibits glutathione S-transferase activity, which plays a role in the detoxification of reactive oxygen species and other electrophilic compounds. Rivaroxaban has been found to be effective against a variety of cancer types, including breast, lung, prostate, and colon cancers. It is a promising candidate for use as an anticancer therapy due to its ability to inhibit protein kinases that are overexpressed in cancer cells.
