Development of Anti-metastatic Drugs Based on Banned Imide-Polyamine Conjugates and Their Application in The Treatment of Liver Cancer

Abstract

The purpose of this study was to develop an anti-metastasis drug based on a banned imide-polyamine conjugate and to explore its application in the treatment of liver cancer. First, we designed and synthesized a series of forbidden imide-polyamine conjugates and evaluated their inhibitory effects on the migration and invasion capacity of HCC cells by cell assay. The results showed that these compounds were able to significantly reduce the metastatic ability of HCC cells. Further mechanistic studies revealed that these compounds are able to inhibit the metastasis of HCC cells by interfering with intracellular signaling pathways and affecting cytoskeletal reorganization. These compounds also showed promising anti-HCC metastatic effects in animal models. To further optimize the structure and activity of these compounds, we optimized their structures using computer-aided design techniques. Through molecular docking and molecular dynamics simulations, we found a number of compounds with higher activity and selectivity. These optimized compounds further validate their anti-metastatic effect in cellular experiments and have less effect on normal cells, showing better biocompatibility. We also explored the mechanism of action of these compounds in HCC treatment. These compounds were found to be able to induce apoptosis in HCC cells and to inhibit their proliferation. At the same time, they can also promote the autophagy and cell cycle arrest of HCC cells, thus inhibiting the development of HCC in many ways. The forbidden imide-polyamine conjugates developed in this study have the potential to serve as novel anti-HCC metastasis agents. In the future, we will continue to optimize the structure and activity of these compounds and conduct clinical trials to validate their efficacy and safety. In addition, we will further explore the mechanisms of these compounds in order to provide new strategies for the prevention and treatment of HCC.
