| Description | 2-Bromopalmitic acid (18263-25-7) inhibits?protein S-palmitoylation.1 Blocks palmitic acid-induced increase in cAMP levels in human primary melanocytes expressing the melanocortin-1 receptor which undergoes an essential palmitoylation as a prerequisite for receptor signaling.2 | | Chemical Properties | WHITE CRYSTALLINE POWDER | | Uses | 2-Bromopalmitic Acid is used in preparation of substituted purines and their analogs for inhibiting the expression of a pattern recognition receptor. | | Definition | ChEBI: A bromo fatty acid that is hexadecanoic (palmitic) acid carrying a single bromo substituent at position 2. | | General Description | PPARδ (peroxisome proliferator-activated receptor, delta isoform) acts as a transcription factor for gene expression as well as playing a role in lipid metabolism regulation; activity of this receptor is ligand-regulated. 2-Bromohexadecanoic acid is a metabolically stable analoge of the fatty acid palmitic acid that has been shown to be a natural ligand for the PPARδ receptor. 2-Bromohexadecanoic acid has also been used in studies of fatty acid oxidation, palmitoylation, and glucose uptake. | | Biochem/physiol Actions | 2-Bromohexadecanoic acid is a PPARδ agonist. It has also been shown to inhibit fatty acid oxidation, inhibit DHHC-mediated palmitoylation, and promote glucose uptake in rat cardiac cells and the insulin-sensitive murine fibroblast line A31-IS. | | Purification Methods | Recrystallise the acid from pet ether (b 60-80o, charcoal) and finally from EtOH. The ethyl ester has b 177-178o/2mm, d28 1.0484, n D 1.4560. [IR: Sweet & Estes J Org Chem 21 1426 1956, Beilstein 2 IV 1184.] | | References | 1) Tsukamoto et al.
