生化/生理作用

胡芦巴(Trigonella foenum-graecum)种子中的 4-羟基异亮氨酸(HIL) 是一种潜在的促胰岛素分泌性(抗糖尿病)和抗肥胖氨基酸。HIL 刺激胰腺细胞葡萄糖依赖性胰岛素分泌。HIL 激活胰岛素受体底物相关的磷酸肌醇 3(PI3)激酶活性。HIL 可降低甘油三酯、游离脂肪酸和胆固醇的血浆水平。
(4S)-4-羟基-L-异亮氨酸(HIL)是一种非蛋白源 α由细菌异亮氨酸双加氧酶(s)活性产生的氨基酸。为了解其促胰岛素的(抗糖尿病)和抗肥胖作用,目前(2S,3R,4S)-HIL 正在研究中。

We report the characterization of a new insulinotropic compound, 4-hydroxyisoleucine. This amino acid has been extracted and purified from fenugreek seeds, which are known in traditional medicine for their antidiabetic properties. 4-Hydroxyisoleucine increases glucose-induced insulin release, in the concentration range

Fenugreek (Trigonella foenum graecum L) is a plant traditionally used for the treatment of diabetes. It contains an unusual amino acid, 4-hydroxyisoleucine, demonstrated to have insulinotropic and antidiabetic properties in animal models. Here we examine the effect of 4-hydroxyisoleucine on

We determined the enzymatic characteristics of an industrially important biocatalyst, α-ketoglutarate-dependent l-isoleucine dioxygenase (IDO), which was found to be the enzyme responsible for the generation of (2S,3R,4S)-4-hydroxyisoleucine in Bacillus thuringiensis 2e2. Depending on the amino acid used as the substrate

Trigonella foenum-graecum, commonly known as fenugreek, is an annual herbaceous plant. From the seeds of T. foenum-graecum an unusual amino acid, 4-hydroxyisoleucine 5, has been isolated, which significantly decreased the plasma triglyceride levels by 33% (P<0.002), total cholesterol (TC) by

4-Hydroxyisoleucine (HIL) found in fenugreek seeds has insulinotropic and anti-obesity effects and is expected to be a novel orally active drug for insulin-independent diabetes. Here, we show that the newly isolated strain Bacillus thuringiensis 2e2 and the closely related strain
