Synergistic effects of CP-25 and 5-fluorouracil on the hepatocellular carcinoma in vivo and in vitro through regulating activating mitochondrial pathway

Paeoniflorin-6'-O-benzene sulfonate (CP-25) has therapeutic potential for the treatment of hepatocellular carcinoma (HCC). 5-Fluorouracil (5-Fu) has been a conventional chemotherapeutic agent for HCC. Unfortunately, the nonspecific cytotoxicity and multidrug resistance caused by long-term use l...

Sumario:Paeoniflorin-6'-O-benzene sulfonate (CP-25) has therapeutic potential for the treatment of hepatocellular carcinoma (HCC). 5-Fluorouracil (5-Fu) has been a conventional chemotherapeutic agent for HCC. Unfortunately, the nonspecific cytotoxicity and multidrug resistance caused by long-term use limited the clinical efficacy of 5-Fu. This study was aimed to investigate whether the combination of CP-25 and 5-Fu could generate synergistic effect in inhibiting HCC. The experiments on the diethylnitrosamine (DEN) -induced mice showed that compared with applying single drugs, the combination of CP-25 and 5-Fu presented stronger inhibition in tumor nodule and volume. Meanwhile, CP-25 and 5-Fu activated the intrinsic mitochondrial apoptosis pathway induced by P53, inhibited anti-apoptotic B-cell lymphoma (Bcl-2), induced the pro-apoptotic Bcl-2-associated X protein (Bax), Cytochrome-C and caspases. In addition, the synergistic effect was also validated in Bel-7402 and HepG-2 cells in vitro. This research not only provides a novel and effective combination strategy for the therapy of HCC but also provides an experimental basis for the development of CP-25 and 5-Fu compound preparation.
