Palmitic Acid methyl ester

Palmitic Acid methyl ester (CAS No.: 112-39-0) is a naturally occurring fatty acid methyl ester widely studied in biomedical research for its immunomodulatory, anti-inflammatory, and antifibrotic properties. It functions in part through inhibition of IκB phosphorylation, thereby influencing NF-κB signaling pathways and leading to reduced expression of pro-inflammatory mediators such as TNF-α and nitric oxide. This compound modulates macrophage activity, suppresses LPS-induced activation in Kupffer cells and peritoneal macrophages, and inhibits phagocytic function in macrophage-like cell lines, highlighting its role in regulating innate immune responses. Additionally, it has been reported to antagonize muscarinic receptors and to exert protective effects in models of ischemia/reperfusion injury, suggesting broader pharmacological relevance. In vitro studies generally demonstrate activity in the nanomolar to micromolar range depending on the assay system and cell type. Palmitic Acid methyl ester is commonly employed in studies investigating inflammatory signaling, immune cell function, and fibrosis-related pathways, as well as in exploratory drug discovery efforts targeting immune and inflammatory disorders, with experimental concentrations or dosing regimens varying according to specific model systems and research objectives.
