Działania biochem./fizjol.

Hymeglusin is a specific β lactone inhibitor of eukaryotic hydroxymethylglutaryl-CoA synthase (HMGCS), a key enzyme in the cholesterol biosynthetic pathway. Unlike other fungal metabolites, Hymeglusin inhibits mevalonate biosynthesis by acting on HMG-CoA synthase, while other fungal metabolites such as Lovastatin (Mevinolin) and Compactin act as specific competitive inhibitors of the HMG-CoA reductase. Inhibition results from covalent modification of the active Cys129 residue by the enzyme by the formation of a thioester adduct in the active site. Hymeglusin show no inhibitory effect against fatty acid synthetase purified from Sacharomyces serevisiae. Hymeglusin was found to block the growth of Enterococcus faecalis. After removal of the inhibitor from the culture medium, a growth curve inflection point is observed. Upon Hymeglusin inactivation, enzyme activity is restored at a rate that is 8-fold faster for human HMGCS than for the bacterial enzyme (mvaS). Structural studies explain these differences. Hymeglusin was also found to inhibit the replication of the dengue live virus (DEN-2 NGC virus) in K562 cells. Lovastatin inhibits DEN-2 NGC live virus replication in human peripheral blood mononuclear cells.

Simple and efficient syntheses of 1233A analogs were developed and the inhibitory activity of the analogs against hydroxymethylglutaryl coenzyme A (HMG-CoA) synthase was determined. Study of the structure-activity relationships revealed that not only the geometry in beta-lactone moiety but also

A beta-lactone isolated from Fusarium sp. has been shown to be a potent specific inhibitor of the enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) synthase [(S)-3-hydroxy-3-methylglutaryl-CoA acetoacetyl-CoA-lyase (CoA-acetylating), EC, 4.1.3.5] from rat liver. The structure of this beta-lactone, termed L-659,699, is (E,E)-11-[3-(hydroxy-methyl)-4-oxo-2-oxytanyl]-3,5,7-trimethyl-2,4

Structural analogs of 1233A, a microbial metabolite inhibiting 3-hydroxy-3- methylglutaryl coenzyme A (HMG-CoA) synthase, were designed and synthesized. The 2-oxetanone moiety was left intact. All analogs prepared were tested for inhibition of HMG-CoA synthase activity and sterol synthesis in mouse

3-Hydroxy-3-methylglutaryl CoA synthase (HMGS) catalyzes the first committed step in the mevalonate metabolic pathway for isoprenoid biosynthesis and serves as an alternative target for cholesterol-lowering and antibiotic drugs. We have determined a previously undescribed crystal structure of a eukaryotic HMGS
