2-Hydroxyisobutyric acid
2-Hydroxyisobutyric acid (2-HIBA) is a selective modulator of the Insulin/IGF-1 pathway and the p38 MAPK pathway, which reduces reactive oxygen species (ROS) and fat accumulation in Caenorhabditis elegans. 2-Hydroxyisobutyric acid promotes β-oxidation and inhibits fatty acid synthesis by upregulating SKN-1/NRF2 and downregulating SREBP-1c transcription factors. 2-Hydroxyisobutyric acid has anti-aging and lipid-lowering effects, and can be used to study metabolic diseases such as obesity and diabetes. 2-Hydroxyisobutyric acid is also a renewable precursor of methacrylate through 2-HIB-CoA mutase-mediated biosynthesis[1][2].
