چکیده

GERI-BP001 compounds, new inhibitors of acyl-CoA:cholesterol acyltransferase (ACAT), were isolated from a culture broth of Aspergillus fumigatus F37 by acetone extraction, EtOAc extraction, SiO2 column chromatography, and reverse phase HPLC. GERI-BP001 M, A, and B inhibit ACAT activity in an enzyme assay system using rat liver microsomes by 50% at concentrations of 42, 94, and 40 microM, respectively.

Gliocladium sp. FO-1513 was found to produce novel inhibitors of acyl-CoA: cholesterol acyltransferase (ACAT). Twoactive compounds, designated glisoprenins A and B, were isolated from the culture broth of the producing strain by a conventional method. The IC50 values of glisoprenins A and B for ACATactivity were 46 and 61fiM in an enzyme assay using rat liver microsomes, and 1.2 and 0.57 /^M in...

Penicillium griseofulvum F1959, high-production strain of pyripyropene a, specific inhibitor of acyl-CoA: cholesterol acyltransferase 2.

Acyl-coenzyme A: cholesterol acyltransferase (ACAT) catalyzes cholesterol esterification and plays an important role in the intestinal absorption of cholesterol, hepatic production of lipoproteins, and accumulation of cholesteryl ester within cells. During the course of screening to find ACAT inhibitors from microbial sources, the present authors isolated pyripyropene A from Penicillium griseof...

Pyripyropenes, novel ACAT inhibitors produced by Aspergillus fumigatus. IV. Structure elucidation of pyripyropenes M to R.

Six new pyripyropenes, M to R, were isolated from the ethyl acetate extracts of the jar fermentation broth of Aspergillus fumigatus FO-1289-2501. Structural elucidation indicated that all the pyripyropenes have the same pyridino-alpha-pyrone sesquiterpene core as pyripyropenes A to L. Among them pyripyropene M showed the most potent inhibition against acyl-CoA : cholesterol acyltransferase acti...
