<p>Flurochloridone (R 40244) is a selective herbicide. Flurochloridone induces apoptosis and is regulated by mitochondrial dysfunction and oxidative stresses.</p>

<p>Methyl mycophenolate impurity E is a reactive, propargylamine-containing, monosodium salt with immunosuppressive properties. It is used in the treatment of cancer by inhibiting the production of white blood cells, which are needed to fight infection. Methyl mycophenolate impurity E has shown antitumor activity and can be used for the treatment of some types of cancer. It is metabolized in vivo to methyl mycophenolate and inhibits protein synthesis by alkylating DNA.</p>

<p>Ellipticine is a powerful cancer drug with different actions, IC50: 0.27-1.48 μM for leukemia, breast cancer, neuroblastoma, glioblastoma.</p>

<p>Des[2-[(2-hydroxyethyl)amino]ethyl] mitoxantrone is a research and development impurity standard for synthesis. It is a synthetic, high purity compound with a CAS number of 89991-52-6. The chemical is not found in nature and does not have any natural metabolites. Des[2-[(2-hydroxyethyl)amino]ethyl] mitoxantrone has been shown to be metabolized by the liver into various metabolites that have been identified through analysis of urine samples. The metabolite of des[2-[(2-hydroxyethyl)amino]ethyl] mitoxantrone may be used as an analytical standard for HPLC methods.</p>

<p>Mycophenolic acid lactone (MPA) is an analytical standard for HPLC, used as a reference material in drug development. It is also a metabolite of mycophenolate mofetil and mycophenolic acid, which are used to treat immunodeficiency disorders. MPA is not active by itself but it can be converted into the active form, mycophenolic acid, by esterases. MPA has been shown to have anti-inflammatory activities and can inhibit the production of prostaglandins in animals. Mycophenolic acid lactone is a metabolite of drugs that are used for the treatment of immunodeficiency disorders, such as mycophenolate mofetil and mycophenolic acid. The chemical structure of MPA is closely related to that of these drugs and it has been shown to have similar anti-inflammatory properties in animal studies.</p>

<p>Camptothecin (CPT) belongs to the alkaloid group of natural products and is a specific DNA topoisomerase I (Topo I) inhibitor (IC50=679 nM) with specificity.</p>

<p>Triacetyl aloe-emodin (impurity A) is an impurity found in the Triacetyl Aloe-Emodin HPLC standard, which is a drug product. It is not approved for use as a drug and should be used only for research and development purposes. The impurity can be custom synthesized or purchased from a specialty chemical supplier. Impurities are not typically found in the final drug product but can occur during synthesis or purification of the API. This impurity is not present in any pharmacopoeia and has no known biological activity. The CAS number of this impurity is 25395-11-3.</p>

<p>Tetrabromobisphenol A is an activator of the hepatic interferon pathway in rats.</p>

<p>Ethacridine acts as an inhibitor of poly (ADP-ribose) glycohydrolase (PARG) and functions as an activator of transcriptional coactivators. It induces apoptosis in thyroid cancer cells and promotes the differentiation of thyroid follicular cells.</p>

<p>Epirubicin, a doxorubicin derivative, is an antineoplastic, inhibits topoisomerase, DNA/RNA synthesis, and Foxp3, reducing T cell activity.</p>

<p>Phacolysine is a chemical compound. Phacolysine is used in ophthalmologic eye lotions.</p>
