Description: Miltefosine is an orally- and topically-active alkyl-phosphocholine compound with potential antineoplastic activity. Miltefosine targets cellular membranes, modulating cell membrane permeability, membrane lipid composition, phospholipid metabolism, and mitogenic signal transduction, resulting in cell differentiation and inhibition of cell growth. This agent also inhibits the anti-apoptotic mitogen-activated protein kinase (MAPK) pathway and modulates the balance between the MAPK and pro-apoptotic stress-activated protein kinase (SAPK/JNK) pathways, thereby inducing apoptosis. As an immunomodulator, miltefosine stimulates T-cells, macrophages and the expression of interleukin 3 (IL-3), granulocyte-macrophage colony stimulating factor (GM-CSF), and interferon gamma (INF-gamma). Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

Additional Information

Miltefosine (INN, trade names Impavido and Miltex) is a phospholipid drug. Chemically it is a derivative of alkylphosphocholine compounds discovered in the early 1980s. It was developed in the late 1980s as an anticancer drug by German scientists Hansjörg Eibl and Clemens Unger. Simultaneously but independently it was found that the drug could kill Leishmania parasites, and since the mid-1990s successful clinical trials were conducted. The drug became the first (and still the only prescribed) oral drug in the treatment of leishmaniasis. It is now known to be a broad-spectrum antimicrobial drug, active against pathogenic bacteria and fungi, as well as human trematode Schistosoma mansoni and its vector host, the snail Biomphalaria alexandrina. It can be administered orally and topically. In the target cell, it acts as an Akt inhibitor. Therefore, it is also under investigation as a potential therapy against HIV infection (
