Quantitation of plasma mevalonic acid using gas chromatography-electron capture mass spectrometry.
Circulating concentrations of mevalonic acid (MVA) change in parallel with, and may be used as a marker of cholesterol biosynthesis. Plasma MVA levels have been quantified using a sensitive and specific capillary gas chromatography-electron capture mass ...

HMG-CoA reductase is not the site of the primary defect in phytosterolemia
Phytosterolemia is an autosomal recessive disorder characterized by the excessive absorption, reduced excretion, and consequent high tissue and plasma levels of plant sterols, by the presence of tendon xanthomas, and by premature atherosclerosis. Low HMG-

The 4G/5G PAI-1 polymorphism influences the endothelial response to IL-1 and the modulatory effect of pravastatin [PDF]
BACKGROUND: Increased plasminogen activator inhibitor (PAI-1) levels lead to impaired fibrinolytic function associated with higher cardiovascular risk. PAI-1 expression may be regulated by different inflammatory cytokines such as interleukin-1alpha (IL-1)

Origin of esterified cholesterol transported in the very low density lipoproteins of human plasma
In two subjects the specific activity of esterified cholesterol in plasma lipoprotein subfractions was measured for up to 9 hr after an intravenous injection of [3H]mevalonic acid.

The role of circulating mevalonate in nephrotic hypercholesterolemia in the rat.
The cause of the hypercholesterolemia that characterizes the nephrotic syndrome has never been adequately explained. The present study examines the possibility that enhanced availability of the cholesterol precursor, mevalonic acid, to the liver in the ...

古来より紫色素は洋の東西を問わず高貴な色として尊ばれてきた。本稿では東洋とヨーロッパで主に流通しているムラサキ科植物を取り上げて基原植物や歴史的な背景を検証した。特にムラサキは日本における自生分布が広く、8~10世紀には各地で栽培が行われ大量の紫根が朝廷へ上納されていた状況について述べた。紫根に含有する紫色素である shikonin は日本で単離構造決定されたのでそれらに付いても言及した。さらにムラサキ科植物の shikonin や光学異性体の alkannin 等の生合成経路についても述べた。又 ...

Short, Enantioselective Synthesis of Mevalonic Acid
A new enantioselective synthesis of mevalonic acid that is short, flexible, scalable to gram amounts, and uses readily available starting materials is reported. Enantioselective homoallylic epoxidation of isoprenol followed by enantiomeric enrichment gave the key epoxide intermediate.
