<p>Doxorubicin impurity 15 is a natural product that is used as an analytical reference standard in pharmacopoeia. It has been synthesized for use in drug development and research and development, and is available as a high-purity HPLC standard. Doxorubicin impurity 15 has a CAS number of 131086-18-5.</p>

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

<p>Mitoxantrone is an anticancer drug that is used to treat various types of cancer. Mitoxantrone is a prodrug, which means it needs to be metabolized by the body to become active. The main metabolic pathway for mitoxantrone involves hydrolysis of the 2-hydroxyethyl piperazine impurity and formation of N-desmethylmitoxantrone, which is a metabolite that has been found to be more potent than the parent compound in inhibiting DNA synthesis. This impurity standard is used as a reference substance for quality control purposes during drug development. Mitoxantrone can also be synthesized with high purity and custom synthesis services are available upon request.</p>

<p>Doxorubicin Dimer Impurity-1 is a drug product that is used as an HPLC standard. It is a metabolite of doxorubicin and has been shown to inhibit DNA synthesis in vitro. This impurity has been detected in the drug product using HPLC, and the purity of this impurity is greater than 98%. Doxorubicin Dimer Impurity-1 is a synthetic compound that has not been found in natural sources. It has been shown to be metabolized by human enzymes, such as esterases, glucuronidases, glutathione reductase, cytochrome P450 enzymes, and glucuronic acid conjugates. Doxorubicin Dimer Impurity-1 may also have anti-inflammatory properties due to its ability to inhibit prostaglandin synthesis.</p>
