N-Acetyltaurine
Based on 1 Customer Validation
N‑acetyltaurine is an orally active endogenous sulfonate that is synthesized from taurine and acetate in the renal cortex. N‑acetyltaurine supports bacterial growth as a sole fixed nitrogen or carbon source. N‑acetyltaurine buffers acetyl moieties of mitochondrial acetyl‑CoA in skeletal muscle. N‑acetyltaurine reduces food intake and body weight in obese and lean wild‑type mice in a GFRAL‑dependent manner. N‑acetyltaurine can be used for the research of diet‑induced obesity, hyperacetatemia and diabetes.

N‑acetyltaurine (100 μM; 1 h) is hydrolyzed into taurine and acetate by recombinant mouse PTER protein, and shows high hydrolytic activity in HEK293T cells overexpressing PTER but no activity in PTER‑KO HEK293T cells[2].
N‑acetyltaurine is synthesized from taurine and acetate in mouse renal cortex homogenate and in primary human skeletal muscle cells[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
N-acetyltaurine (15-50 mg/kg; i.p.; daily; 7 days) reduces body weight and food intake in healthy chow-fed male mice[2].
N-acetyltaurine (15 mg/kg; i.p.; daily; 7 days) reduces body weight and food intake in DIO male mice[2].
N-acetyltaurine (15 mg/kg; i.p.; daily; 7 days) reduces body weight and food intake in DIO male Mc4r KO mice, indicating the effects of N-acetyltaurine do not require functional MC4R receptors[2].
N-acetyltaurine (50-500 mg/kg; p.o.; daily; 7 days) administered orally to DIO male mice reduces body weight and food intake in a dose-dependent manner, with significant effects observed at doses of 150 mg/kg and 500 mg/kg daily for 7 days, and achieves measurable plasma levels following oral gavage[2].
N-Acetyltaurine levels were increased in response to Triacetin (HY-B0896)-induced hyperacetatemia[5].
N-Acetyltaurine levels were significantly increased in response to endogenous hyperacetatemia from Streptozotocin (HY-13753)-induced diabetes[5].
