2-chloro Palmitic acid is a monochlorinated form of palmitic acid . It is produced in a myeloperoxidase (MPO) and time-dependent manner in neutrophils stimulated by phorbol 12-myristate 13-acetate (PMA; ). 2-chloro Palmitic acid (10 μM) induces neutrophil extracellular trap (NET) formation (NETosis) in human neutrophils, increasing DNA release from neutrophils, colocalization of MPO with extracellular DNA (ecDNA), and trapping of E. coli. It increases COX-2 protein levels in human coronary artery endothelial cells (HCAECs) when used at a concentration of 50 μM and increases production of P-selectin, von Willebrand factor, and angiopoietin-2 in HCAECs, as well as neutrophil and platelet adherence, when used at a concentration of 10 μM. 2-chloro Palmitic acid (10-50 μM) also induces apoptosis in THP-1 cells and primary human monocytes and increases caspase-3 activity in THP-1 cells.
2-chloro Palmitic Acid, an inflammatory lipid mediator, interferes with protein palmitoylation,induces ER-stress markers, reduced the ER ATP content, and activates transcription and secretion of IL-6 as well as IL-8.2-chloro Palmitic Acid disrupts the mitochondrial membrane potential and induces procaspase-3 and PARP cleavage.2-chloro Palmitic Acid can across blood-brain barrier (BBB) and compromises ER- and mitochondrial functions in the human brain endothelial cell line hCMEC/D3.
体外研究
2-chloro Palmitic Acid (2-ClHA; 10 μM; 4, 6 h) results phosphorylation of eIF2α starting 4 h post treatment, while total eIF2α levels remained unchanged incubation of hCMEC/D3 cells. 2-chloro Palmitic Acid increases expression of ATF4, a target gene of eIF2α.
2-chloro Palmitic Acid (25 μM, 30 min) induces a decrease in the FRET ratio signal of ERAT by 40%, indicating significantly diminished [ATP]ER in cells that were treated with 2-chloro Palmitic Acid.
