4-ethylphenyl sulfate
4-Ethylphenyl sulfate is a microbiota-derived metabolite structurally related to p-cresol (4-methylphenol) and classified as a uremic toxin. Elevated serum concentrations have been detected in chronic renal failure patients, suggesting potential utility as a biomarker for renal function. In murine models of autism induced by maternal immune activation (MIA), serum levels of 4-ethylphenyl sulfate significantly increased. Administration to healthy mice induced anxiety-like behaviors and amplified startle sensitivity without affecting pre-pulse inhibition, indicating involvement in behavioral and neurological modulation. This compound serves as a promising research tool for studying gut microbiota-brain interactions in autism-spectrum disorders and renal dysfunction.
