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 is a potent and specific inhibitor of liver and intestinal acyl coenzyme A:cholesterol acyltransferase (ACAT) in vitro.
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.

R-755 (N-(2,6-diethylphenyl)-N'-[3-(2-methylphenyl)-6,7-dihydro-5H-cyclopenta[f[l]benzothiophen-2-yl]urea), a novel acyl-CoA:cholesterol acyltransferase (ACAT) inhibitor, has been characterized in vitro, ex vivo and in vivo. R-755 potently inhibited ACAT activities, with IC50 values from 2.5 to 64 nM, in rabbit intestinal microsomes and several cell lines (CaCo-2

Recent studies have suggested that formation of Golgi membrane tubules involves the generation of membrane-associated lysophospholipids by a cytoplasmic Ca2+-independent phospholipase A2 (PLA2). Herein, we provide additional support for this idea by showing that inhibition of lysophospholipid reacylation by a

In the course of our search for anti-angiogenic substances, pyripyropenes A (1), B (2), and D (3) were re-discovered as selective anti-proliferative substances against human umbilical vein endothelial cells (HUVECs) from a marine-derived fungus of Aspergillus sp. Pyripyropenes showed potent

FR129169 (FR) (N-(1,2-diphenylethyl)-2-octyloxyphenylacetamide) has been found to inhibit acyl-CoA:cholesterol acyltransferase (ACAT) activities in intestinal microsomes of rats and rabbits and the liver homogenate of rats with IC50 values of around 1.0 x 10(-7) M. The inhibitory activity was 2-3 times
