Description

4-Hydroxyisoleucine is an orally active amino acid that can be isolated from fenugreek seeds. 4-Hydroxyisoleucine displays insulinotropic and antidiabetic properties[1].

In Vitro

4-Hydroxyisoleucine (20 μM, 6 h) decreases the level of iRhom2, TACE, TNF-α and MCP-1 in RAW264.7 macrophages and 3 T3-L1 adipocytes with LPS (HY-D1056) induction[2].
4-Hydroxyisoleucine (20 μM, 6 h) increases the product of M1 macrophage IL-6 and decreases the product of M2 macrophage IL-10 in the co-culture system with LPS (HY-D1056) stimulation[2].
4-Hydroxyisoleucine (0-25 μM, 16 h) increases glucose uptake and surface GLUT4myc level in L6-GLUT4myc myotubes in a concentration-dependent manner[3].
4-Hydroxyisoleucine (0-25 μM, 16 h) stimulates GLUT4myc translocation via PI-3-K/AKT-dependent mechanisms in L6-GLUT4myc myotubes[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis[3]

Cell Line: L6-GLUT4myc
Concentration: 25 μM

Didn’t effect mRNA levels of IRS-1, AKT, GSK3b, or GLUT4 in L6-GLUT4myc myotubes.
In Vivo

4-Hydroxyisoleucine (50 mg/kg, p.o., daily, 8 weeks) inhibits the increase in serum glucose in the fructose-fed rat model of metabolic syndrome[1].
4-Hydroxyisoleucine (200 mg/kg, p.o., 8 weeks) improves dyslipidemia and reduces lipid ectopic accumulation in C57BL/6 mice[4].
4-Hydroxyisoleucine (200 mg/kg, p.o., 8 weeks) decreases the expression of proinflammatory cytokine (IL-6, PAI-1, IL-1β, NF-κB, TNF-α, and MCP-1) and the proportion of proinflammatory M1 macrophages in C57BL/6 mice[4].
4-Hydroxyisoleucine (50 mg/kg, i.g., daily, 14 days) restores high levels of lipids (cholesterol, HDL, LDL and triglycerides) and uric acid in type 1 diabetic rat to that of nondiabetic controls level[5].

Animal Model: Fructose-fed rat[1]
Dosage: 50 mg/kg
Administration: Oral gavage (p.o.), daily, 8 weeks
Result: Decreased the levels of glucose and ALT.
Reduced 80% of fructosehe-induced AST release to 151 ± 45 U/mL.
Animal Model: Type 2 diabetic rat[1]
Dosage: 50 mg/kg
Administration: i.g., daily, 14 days
Result: Restored the level of HDL-cholesterol to levels comparable to controls.
Animal Model: Male C57BL/6 mice[4]
Dosage: 50-200 mg/kg
Administration: Oral gavage (p.o.), 8 weeks
Result: Decreases the body weights of mice in a dose-dependent manner.
Decreased blood glucose levels and fasting plasma insulin content in mice.
Decreased the expression of TLR4, inhibited the phosphorylation of JNK, and increased the production of IκB-α.
Animal Model: Type 1 diabetic rat[5]
Dosage: 50 mg/kg
Administration: i.g., daily, 14 days
Result: Improved appearance and heavy ocular vascularization.
Reduced the blood glucose from 500 mg/dl to 330 mg/dl.
Decreased the levels of lipid markers (TG, LDL and HDL) and uric acid.
Didn’t increase the level of inculin compared with untreated diabetic controls.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
