H-Leu-Ser-Lys-Leu-OH (LSYL) is a latency-associated peptide at the amino terminus of LAP, with inhibitory effect on TGF-β1 activation. H-Leu-Ser-Lys-Leu-OH, binding with KRFK (HY-P3970), can block the signal transduction of TGF-β1, and prevent the progression of hepatic damage and fibrosis[1].

Target	TGF-β1[1]
In Vitro	H-Leu-Ser-Lys-Leu-OH (LSKL) 也可以阻断 TSP-1 对 TGF-β1 的激活，并降低 KRFK 肽对 TGF-β1 的激活[1]。
In Vivo	H-Leu-Ser-Lys-Leu-OH (LSKL) (100 μg/0.5 mL; 腹腔注射; 每日给药，共 4 周; 并伴随着 DMN 的处理) 能够保护二甲基亚硝胺 (DMN) 处理 (10 mg/kg; 腹腔注射; 每周连续3天给药, 共 4 周) 导致的大鼠肝萎缩。H-Leu-Ser-Lys-Leu-OH 还可以预防肝损伤和纤维化的进展[1]。
