DL-Palmitoylcarnitine (chloride) is a long-chain acylcarnitine with both intracellular and extracellular roles. Within the cell, palmitoylcarnitine is transported into mitochondria to deliver palmitate for fatty acid oxidation and energy production. Exogenously added DL-palmitoylcarnitine alters calcium mobilization in many cell types. It also affects endothelial and epithelial tight junctions, reducing resistance and increasing permeability while decreasing cell viability.
Palmitoyl-DL-carnitine chloride is a specific protein kinase C (PKC) inhibitor.
Palmitoyl-DL-carnitine chloride has been used to study its effect on inflammatory cytokines and calcium (Ca2+) influx, using in vitro models of prostate cancer.
Palmitoyl-DL-carnitine chloride is known to inhibit biofilm formation mediated by Pseudomonas aeruginosa and Escherichia coli. It is a phosphokinase C inhibitor.
