ZLDI-8 is a Notch activating/cleaving enzyme ADAM-17 inhibitor and inhibits the cleavage of Notch protein. ZLDI-8 decreases the expression of pro-survival/anti-apoptosis and epithelial-mesenchymal transition (EMT) related proteins. ZLDI-8 is also a competitive and irreversible tyrosine phosphatase (Lyp) inhibitor with an IC50 of 31.6 μM and a Ki of 26.22 μM. ZLDI-8 inhibits the growth of MHCC97-H cells with an IC50 of 5.32 μM.
体外研究
ZLDI-8 (0.03-30 μM; 6-72 hours; MHCC97-H cells) treatment reduces cell viability in a time- and dose-dependent manner.
ZLDI-8 (1-10 μM; 6-72 hours; MHCC97-H cells) significantly decreases the level of NICD and the accumulation of NICD in the nucleus. ZLDI-8 could also reduce the expression of pro-survival/anti-apoptosis regulators, Survivin and cIAP1/2. And also increases the expression of epithelial marker E-Cadherin and reduced mesenchymal markers N-Cadherin and Vimentin.
ZLDI-8 enhances chemotherapy effects on tumor cell proliferation blockage, induction of apoptosis and cell-cycle arrest by inhibiting Notch pathway and blocking chemical resistance.
