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

2-Bromopalmitic Acid is used in preparation of substituted purines and their analogs for inhibiting the expression of a pattern recognition receptor.

ChEBI: A bromo fatty acid that is hexadecanoic (palmitic) acid carrying a single bromo substituent at position 2.

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.

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.]
