<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>Pitavastatin N-oxide is a drug product that is an analytical standard and natural API impurity. It is used in the synthesis of other drugs, such as pitavastatin, which is a statin drug used to lower cholesterol levels. Pitavastatin N-oxide has been shown to be a potent inhibitor of HMG-CoA reductase, the enzyme that catalyzes the conversion of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) to mevalonate. This inhibits cholesterol production and lowers levels of low density lipoprotein (LDL) cholesterol in the blood.</p>
