| Description | Z-FY-CHO (Z-Phe-Tyr-CHO) is a selective histone L (Cat L) inhibitor that promotes autophagy, reduces the accumulation of P62, and blocks the activation of caspase-3 and PARP. |
| In vitro | Cell death induced by 6-OHDA was reduced using Z-FY-CHO (10 μM, 1 h pretreatment).Z-FY-CHO inhibited the increase in CTSL protein expression in 6-OHDA-treated SH-SY5Y cells.Z-FY-CHO treatment resulted in an increase in LC3-II expression and a decrease in P62 expression was decreased, indicating enhanced autophagic activity. In addition, Z-FY-CHO blocked the activation of caspase-3 and PARP. [1] The radiosensitization of U251 cells was significantly improved by using the specific cathepsin L inhibitor Z-FY-CHO (10 μM) or transfection with cathepsin L shRNA. Both inhibition and knockdown of cathepsin L in U251 cells enhanced radiation-induced DNA damage and G2/M phase cell cycle arrest. Also, inhibition or knockdown of cathepsin L increased radiation-induced apoptosis as evidenced by elevated Bax levels and decreased Bcl-2 levels. [2] |
| In vivo | In an ovariectomized mouse model of osteoporosis, intraperitoneal injection of Z-FY-CHO (2.5-10 mg/kg) for 4 weeks was able to dose-dependently reduce bone weight loss.Z-FY-CHO acts as an inhibitor of bone resorption by inhibiting collagen degradation. [3] |
