CT-2584 (166981-13-1; free base) is a cytotoxic agent that alters phospholipid biosynthesis via inhibition of CTP:choline-phosphate cytidylyltransferase causing an increase in phosphatidylinositol with decreasing levels of phosphatidylcholine.1?The altered phospholipid metabolism caused by CT-2584 results in a loss of lamellar structure and membrane integrity (especially in mitochondria and endoplasmic reticulum). CT-2584 was active against a wide range of tumor cell lines including multi-drug resistant lines.2
