PRGL493 is a potent and selective long-chain acyl-CoA synthetase 4 (ACSL4) inhibitor. PRGL493 blocks cell proliferation and tumor growth in both breast and prostate cellular and animal models.
PRGL493 inhibits formation of arachidonoyl-CoA (AA-CoA) from arachidonic acid in, as well as the proliferation and migration of, PC3 and MDA-MB-231 cancer cells when used at a concentration of 50 μM. PRGL493 (5 μM) reduces production of progesterone induced by 8-Br-cyclic AMP (8-Br-cAMP) in MA-10 Leydig tumor cells.
PRGL493 inhibits tumor growth in a PC3 mouse xenograft model when administered at a dose of 0.25 mg/kg.

ACSL4 coordinates metabolic and cell cycle reprogramming to promote endometrial cancer progression.
