Abstract:Background: Omacetaxine mepesuccinate (OM) is a semi-synthetic form of Homoharringtonine (HH), a cephalotaxine alkaloid. OM induces cell apoptosis by inhibiting peptide bond formation during mRNA translation, with rapid loss of short-lived proteins, such as MCL-1, c-MYC, and Cyclin D1 (Lu, J Hematol Oncol. 2014, 7: 2). Notably, cytarabine synergizes with HH in causing apoptosis of leukemia cells in vitro. A phase III RCT in China of 620 patients with de novo AML demonstrated superior CR and 3-yr survival rates… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
