IPM712, a vanillin derivative as potential antitumor agents, displays better antitumor activity in colorectal cancers cell lines.

Colorectal cancer (CRC), a major health threat in the world, ranks third in incidence and second in mortality among cancers. Chemotherapy, an important treatment for colorectal cancer, have be limited in the clinic due to the resistance and side effect. Studies have shown that PI3K-related regulatory pathways play a colossal role in colorectal cancer. Therefore, it is a good strategy to find a new drug which works by affecting the PI3K signaling pathway. In this paper, we obtained a new vanillin derivative (IPM712) by modifying the structure of IPM711 and tested its anticancer activity in vitro and toxicity in vivo. Results showed that IPM712 has a better anticancer activity than 5-Fu in HCT116 and SW480 cell lines. Furthermore, IPM712 can inhibit cell proliferation, migration and induce the apoptosis by affecting PI3K-related protein expression. Acute toxicity experiments show that IPM712 has no significant toxicity at therapeutic concentrations. Based on these results, IPM712 is a promising anticancer drug candidate for human colorectal cancer therapy.
