General description
Isobutyric acid is a carboxylic acid used as a building block in the production of active pharmaceutical ingredients (APIs).
Application
Isobutyric acid can be used:
- to synthesize butyl isobutyrate via esterification with n-butanol using lipases
- as a precursor for Methacrylic acid (MAA) through catalytic oxidative dehydrogenation. It can be produced through fermentative pathways

Birth by Caesarean (C)-section impacts early gut microbiota colonization and is associated with an increased risk of developing immune and metabolic disorders. Moreover, alterations of the microbiome have been shown to affect neurodevelopmental trajectories. However, the long-term effects of C-section

Matrix metalloproteinases (MMPs) degrade extracellular matrix components, and overexpression of these enzymes contributes to tissue destruction in arthritis. Of particular importance are the collagenases, MMP-1 and MMP-13, which have high activity against the interstitial collagens in cartilage. In this study

Histone deacetylase inhibitors (HDACi) have neuroprotective effects under various neurodegenerative conditions, e.g., after optic nerve crush (ONC). HDACi-mediated protection of central neurons by increased histone acetylation has not previously been demonstrated in rat retinal ganglion cells (RGCs), although epigenetic changes
