Aim To explore the signaling pathway of matrine derivative ZS10 in inhibiting proliferation and inducing apoptosis of BEL-7402 cells. Methods ZS10 was synthesized by organic synthesis. The inhibitory effect of ZS10 on the proliferation of BEL-7402 cells was analyzed by MTT method at the time of 24 h, 48 h and 72 h, respectively, and IC50 was calculated. DAPI staining was used to observe the state of BEL-7402 cells. Clone formation method was used to observe the colony formation of BEL-7402 cells, flow cytometry was used to observe the cell cycle arrest and apoptosis of BEL7402 cells, and Western blot was used to detect the expression level of PI3K/AKT pathway and related proteins. Results MTT results showed that the IC50 was(6.62±1.11)μmol·L-1; DAPI staining showed that the cell state changed significantly with the increase of drug concentration, and the results of colony formation showed that ZS10 significantly inhibited the colony formation of BEL-7402 cells. The results of flow cytometry showed that ZS10 induced S phase arrest and cycle apoptosis of BEL-7402 cells. Western blot showed that ZS10 at the concentration of 0～8 μ mol·L-1 could regulate the PI3K/AKT pathway and its related proteins in a dose-dependent manner. Compared with the control group, the expression of PI3K, AKT, P-AKT and anti-apoptotic protein Bcl-2 significantly decreased, the expression of pro-apoptotic protein Bax significantly increased, the expression of Cyclin D1 and CDK2 significantly decreased, and the expression of EGFR and N-cadherin, Vimentin significantly decreased in the treatment group. The expression of E-cadherin increased. Conclusions Matrine derivative ZS10 can inhibit the growth and proliferation of hepatocellular carcinoma cell line BEL-7402. © 2023 Publication Centre of Anhui Medical University.
