What is Idroxioleic acid?

Plain description, key identifiers and synonyms

2-hydroxyoleic acid is a 2-hydroxy fatty acid that is oleic acid which carries a hydroxy group at position 2. It is an orally bioavailable synthetic hydroxylated fatty acid which modulates the lipid content of cancer cell membranes and induces cell cycle arrest and apoptosis in several cancer cell lines. It has a role as an antineoplastic agent, an antihypertensive agent and an apoptosis inducer. It is a 2-hydroxy fatty acid, a hydroxy monounsaturated fatty acid and a long-chain fatty acid. It is functionally related to an oleic acid. It is a conjugate acid of a 2-hydroxyoleate.

Pharmacology

Idroxioleic Acid is an orally bioavailable, synthetic analog of the fatty acid oleic acid, with potential antitumor activity. Upon administration,idroxioleic acid activates sphingomyelin synthase (SMS), thereby increasing the concentration of sphingomyelin (SM) and diacylglycerol (DAG) in the tumor cell membrane and decreasing membrane levels of phosphatidylethanolamine (PE) and phosphatidylcholine (PC). This restores the normal, healthy levels and ratios of membrane lipids.

By restoring normal membrane lipid structure and composition, this agent inhibits membrane-protein associated signaling and the aberrant activity of signaling pathways in certain tumor cells, including the Ras/MAPK and PI3K/AKt pathways. This inhibits tumor cell proliferation, induces tumor cell differentiation, and eventually can cause cell death.
