We have previously demonstrated that N-acetylleucine amide, a derivative of L-leucine, inhibits leucine-induced p70(S6k) activation in a rat hepatoma cell line. In the present study, we investigated whether N-acetylleucine amide is capable of inhibiting amino acid-mTOR signaling. N-Acetylleucine amide caused cell cycle arrest at G1 stage in Jurkat cells, a human leukemia T cell line, concomitant with the inhibition of serum-induced p70(S6k) activation and p27 degradation. Treatment of Jurkat cells with this compound also exhibited dephosphorylation of retinoblastoma protein. These effects are similar to the inhibitory effects of rapamycin on amino acid-mTOR signaling pathway and suggest that N-acetylleucine amide acts as a rapamycin-like reagent to inhibit cell cycle progression in Jurkat cells.
