Cationic Amphiphilic Dendrons with Anticancer Activity.

Cancer has become the leading cause of human death worldwide, and there is an urgent need to design and develop new oncology drugs. In this study, we report series of cationic amphiphilic dendrons with different hydrophobic alkyl chains (Cn) and different generations (Gx) and demonstrate their use for anticancer applications. The results revealed that lower-generation dendrons (G1) with a longer hydrophobic alkyl chain (C12 and C18) have stronger antitumor activity. Among these dendrons, a lead candidate C12-G1 was identified that demonstrated excellent broad-spectrum antitumor activity in 7 cancer cell lines including highly metastatic tumor cells, while simultaneously, hemolysis was negligible. Mechanistic studies showed that C12-G1 could lead to cytoplasmic leakage and induce cancer cell necrosis through membrane disruption. In addition, C12-G1 showed potent inhibition of tumor growth in a B16-F10 melanoma model. In conclusion, these findings demonstrate that the cationic amphiphilic dendron might be a promising agent for anticancer application.
