In-vivo and in-vitro study of mechanism of action of 4 hydroxyisoleucine as an amino acid derived from fenugreek seed with anti-diabetic and properties
type: CreativeWork
description: Diabetes is a progressive multi-factorial metabolic syndrome with serious short and long term complications affecting many of organs with high increasing prevalence in the world. Using herbs and their derivatives for treating diabetes has a long history in many traditional cultures across the world. Molecules and compounds were isolated from herbs are the basis of many therapeutics which we are using in medicine for treating a variety of health conditions. The seeds of fenugreek, Trigonella foenum graecum, commonly used as a spice in Middle Eastern countries and widely used in South Asia and Europe, are known to have anti-diabetic properties. In 1979, Hardman identified an unusual amino acid (2S, 3R, 4S) 4-hydroxyisoleucine (4HO-Ile) in a fenugreek seed extract as an active compound in fenugreek seed. It was so far found only in fenugreek seed, which is responsible for its anti-diabetic properties. Studies on 4-hydroxyisoleucine effects on type 2 diabetes and insulin resistant animal models revealed that it has anti-diabetic properties of enhancing insulin secretion under hyperglycaemic conditions, and increasing insulin sensitivity. Unfortunately, the available published researches for 4-hydroxyisoleucine are limited and its mechanism of actions is not clear. Here we describe for the first time the anti-diabetic activity of 4-hydroxyisoleucine in a model of type 1 diabetes as all the previous works focused on 4-hydroxyisoleucine activity in type 2 diabetes and insulin resistant condition. Treatment of streptozotocin-treated type 1 diabetes rats, where levels of insulin are much reduced, by 65%, compared to normal animals, with daily doses of 4-hydroxyisoleucine at 50 mg/kg/day for four weeks could reduce plasma glucose in the diabetic group. Moreover the high levels of lipids (cholesterol, HDL, III LDL and triglyceride) and uric acid in the diabetic rats, could be restored to levels found in non-diabetic controls by the treatment with 4-hydroxyisoleucine. These res…
