Isovaleric acid

3-Methylbutanoic acid is an antimicrobial agent that belongs to the group of isovaleric acids. It is a product of β-oxidation and has been shown to inhibit the growth of bacteria by reacting with their surface. 3-Methylbutanoic acid inhibits bacterial growth by binding to the pyrazole ring in DNA and altering its conformation, preventing DNA replication. This reaction occurs at a rate comparable to that of other fluoroquinolones, such as ciprofloxacin, levofloxacin, and norfloxacin. 3-Methylbutanoic acid has been shown to have antibacterial activity against both Gram-positive and Gram-negative bacteria, particularly those that are resistant to erythromycin or lincomycin.
