Background

4-Hydroxyphenylacetic acid is a phenolic acid with anti-inflammatory and anti-steatotic activities.^1,2 It is formed via microbial metabolism of aromatic amino acids and polyphenolic compounds, including flavonoid glycosides, by gut microbiota.^3,4,5 4-Hydroxyphenylacetic acid (100 mg/kg) inhibits seawater instillation-induced increases in TNF-α, IL-1β, and IL-6 levels in lung tissue and white blood cell numbers in bronchoalveolar lavage fluid (BALF) and prevents lung edema in a rat model of acute lung injury.¹ It reverses hepatic steatosis in a mouse model of high-fat diet-induced obesity when administered via a subcutaneous implant at a dose of 350 ?g/day for two weeks.² Levels of 4-hydroxyphenylacetic acid are increased and decreased in serum and urine, respectively, in rats fed a high-fat diet.³ Serum levels of 4-hydroxyphenylacetic acid are increased in patients with stage III pancreatic cancer.⁶
