生物活性:
Antitumor agent-81 (compound 5a) is a low cytotoxic P62-RNF168 agonist that promotes the interaction of P62 with RNF168. Antitumor agent-81 induces a decrease in RNF168-mediated H2A ubiquitination and impairs homologous recombination-mediated DNA repair. Antitumor agent-81 also inhibits mice xenograft tumor growth in a dose-dependent manner.

体外研究:
Antitumor agent-81 (0-20 μM; 72 h) exhibits antiproliferative activity in cells of the most common cancer types.Antitumor agent-81 (1, 2, 5 μM; 24 h) compromises HR (homologous recombination)-mediated DSB repair in HCT-116 cells.Antitumor agent-81 tethers the interaction between P62 and RNF168 in HCT-116 cells.Antitumor agent-81 inhibits the catalytic activity of RNF168 and RNF168 E3 ligase activity in HCT-116 cells.
