Description
PTK is an analog of palmitic acid in which the COOH group is replaced by trifluoromethyl ketone. In P388D1 cells, PTK inhibits iPLA
2 activity with an IC
50 value of 3.8 μM. A related compound, ATK is a less potent inhibitor of iPLA
2 with an IC
50 value of 15 μM. PTK also inhibits the activity of cPLA
2 with an IC
50 value almost identical to that of ATK.
Uses
PACOCF3 is an inductors of BLM, an artificial lipid membranes and liposome permeabilization. Phospholipase A2 inhibitor.
Definition
ChEBI: Palmityl Trifluoromethyl Ketone is an alpha-haloketone.
Biological Activity
Phospholipase A 2 inhibitor. Can also alter Ca 2+ signaling in renal tubular cells.
