Aminated fullerene has significant anti-tumor effects, and the newly synthesized TAPC-4 can inhibit tumor cell proliferation by blocking cell cycles, reversing epithelial-mesenchymal transition, and suppressing tumor cell mobility. TAPC-4 can also be excreted from the body and has a wide safety margin. Molecular dynamics simulations reveal that the amphiphilic molecular structure and terminal amino groups promote the targeting of TAPC-4 to specific proteins, which may alter the translation and expression of related genes, and thus play an anti-tumor role.
Malignant proliferation and metastasis are the hallmarks of cancer cells. Aminated [70]fullerene exhibits notable antineoplastic effects, promoting it a candidate for multi-targeted cancer drugs. It is an urgent need to reveal the structure-activity relationship for antineoplastic aminated fullerenes. Herein, three amphiphilic derivatives of [60]fullerene with clarified molecular structures are synthesized: TAPC-4, TAPC-3, and TCPC-4. TAPC-4 inhibits the proliferation of diverse tumor cells via G0/G1 cell cycle arrest, reverses the epithelial-mesenchymal transition, and abrogates the high mobility of tumor cells. TAPC-4 can be excreted from the organism and achieves an in vivo inhibition index of 75.5% in tumor proliferation and 87.5% in metastatic melanoma with a wide safety margin. Molecular dynamics simulations reveal that the amphiphilic molecular structure and the ending amino groups promote the targeting of TAPC-4 to heat shock protein Hsp90-beta, vimentin, and myosin heavy chain 9 (MYH9), probably resulting in the alteration of cyclin D1 translation, vimentin expression, and MYH9 location, respectively. This work initially emphasizes the dominant role of the amphiphilic structure and the terminal amino moieties in the antineoplastic effects of aminated fullerenes, providing fundamental support for their anti-tumor drug development.
