Application

CI 976 has been used as an acyl-coenzyme A: cholesterol acyltransferase (ACAT) inhibitor:
  • to analyze its anti-hepatitis C virus (HCV) activity in Huh7.5.1 cells
  • to treat Neuro-2a cells to test its effect on plasma membrane integrated density of α4-SEPβ2 or α6-SEPβ2β3 nicotinic acetylcholine receptors (nAChRs)
  • to study its effects on the anti-angiogenic activity of pyripyropenes in human umbilical vein endothelial cells

Biochem/physiol Actions

CI-976, a new trimethoxy fatty acid anilide, is a potent and specific inhibitor of liver and intestinal acyl coenzyme A; cholesterol acyltransferase (ACAT) in vitro. CI-976 decreased non-high density lipoprotein (HDL)-cholesterol and increased HDL-cholesterol in rats with pre-established dyslipidemia. High performance gel chromatographic separation of plasma lipoproteins also revealed that CI-976, but not CL 277,082, lowered low density lipoprotein (LDL)-cholesterol and elevated HDL-cholesterol.

1. A novel ACAT (acyl-CoA: cholesterol acyltransferase) inhibitor, HL-004, exhibited a strong inhibitory effect on the hepatic and intestinal ACAT, but was less effective on the adrenal ACAT in vitro. 2. HL-004 selectively decreased serum VLDL cholesterol, and inhibited hepatic

Previous studies have shown that inhibition of a Golgi-complex-associated lysophospholipid acyltransferase (LPAT) activity by the drug CI-976 stimulates Golgi tubule formation and subsequent redistribution of resident Golgi proteins to the endoplasmic reticulum (ER). Here, we show that CI-976 stimulates tubule

A series of N-alkyl-N-biphenylylmethyl-N'-arylurea and related derivatives represented by 1 have been prepared and evaluated for their ability to inhibit acyl-CoA:cholesterol O-acyltransferase in vitro and to lower plasma cholesterol levels in cholesterol-fed rats in vivo. Linking of two phenyl groups

Acyl CoA: cholesterol acyltransferase (ACAT) inhibitors are known to inhibit cholesterol absorption and are under investigation to reduce hypercholesterolemia. These studies examine the effect of an ACAT inhibitor 2,2-dimethyl-N-(2,4,6-trimethoxyphenyl)-dodecanamide (PD128042) on the uptake, metabolism and secretion of cholesterol by the

We studied the effect of NTE-122 (trans-1,4-bis[[1-cyclohexyl-3-(4-dimethylamino phenyl) ureido]methyl]cyclohexane), a novel acyl-CoA:cholesterol acyltransferase (ACAT) inhibitor, on intracellular cholesterol esterification and the secretion of apolipoprotein B100 (apoB)-containing lipoprotein and bile acids in the human hepatoma cell line HepG2. NTE-122 markably inhibited
