Usage And Synthesis

Description

BMS-303141 (943963-47-8) is a potent and selective ATP citrate lyase (ACL) inhibitor, IC50=0.13 μM. Inhibits lipid biosynthesis, IC50=8 μM in HepG2 cells.1,2Reduces weight gain, lowers plasma cholesterol, triglycerides and glucose in high-fat-fed mice.2A novel tool compound for exploring the potential of ACL inhibition as a target for metabolic disorders such as obesity and dyslipidemia.2Impairs proliferation or induces death in androgen-depleted castration resistant prostate cancer cells.3Reduces cell cycle progression in iBN cells.4

Uses

BMS-303141 has been used for inhibition of ATP citrate lyase in breast cancer cell lines.

Definition

ChEBI: 3,5-dichloro-2-hydroxy-N-(2-methoxy-5-phenylphenyl)benzenesulfonamide is a member of biphenyls.

Biochem/physiol Actions

BMS-303141 is a potent inhibitor of ATP citrate lyase (ACL). BMS-303141 inhibits lipid synthesis in HepG2 cells with an IC50 of 8 μM, and lowers plasma triglycerides in a murine hyperlipdemia model.

storage

Store at -20°C

Background

The small-molecule BMS-303141 is a potent inhibitor of ATP-citrate lyase. ACL catalyzes the formation of cytosolic acetyl-CoA and oxaloacetate in the cytosol, which is the key step for fatty acid and cholesterol biosynthesis. BMS-303141 also weakly inhibits acetyl-CoA carboxylase isoforms ACC1 and ACC2. Treatment of high-fat fed mice with BMS-303141 reduced weight gain and decreased levels of plasma cholesterol, triglycerides, and glucose. BMS-303141 treatment of prostate cancer cells impaired cell proliferation or induced death in androgen-depleted, castration-resistant prostate cancer cells. Hepatocellular carcinoma cells responded to treatment with BMS-303141, reducing cell proliferation and promoting apoptosis. BMS-303141 is thought to induce endoplasmic reticulum stress and activate the p-eIF2α/ATF4/CHOP pathway to promote apoptosis. The combined treatment of a mouse xenograft model with BMS-303141 and a protein kinase inhibitor reduced tumor volume and weight.
