Résumé
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death, but effective therapeutic strategies are limited. Transcriptional factor c-Myc plays an oncogenic role in tumorigenesis and is an attractive target for HCC treatment. However, targeted therapy against c-Myc remains challenging. Herein, by conjugating VH032 with an optimized DNA sequence that recognized c-Myc complex, we discovered oligonucleotide-based proteolysis targeting chimeras (PROTACs), termed as MP-16 and MP-17, which effectively induced degradation of c-Myc. Mechanically, MP-16 or MP-17 directly interacted with c-Myc complex to form VHL/PROTAC/c-Myc ternary complex, and triggered c-Myc degradation by recruiting ubiquitin-proteasome system, suppressing cell proliferation of HCC cells. In mice model, MP-16 or MP-17 significantly inhibited HCC tumor growth and exhibited promising drug safety. This work provided novel oligonucleotide PROTACs that degraded c-Myc, giving a new lead structure for HCC therapy.
