Among these, compound 10 h demonstrated the most potent antiproliferative effect (IC50 = 4.05 ± 0.67 μM), significantly outperforming the reference drug 5-fluorouracil (IC50 = 17.43 ± 4.66 μM), while exhibiting minimal toxicity toward normal liver L02 cells (IC50 > 40 μM). In vivo, 10 h significantly suppressed tumor growth in a HepG2 xenograft model without overt toxicity. Collectively, these findings establish 10 h as a highly potent and selective anticancer lead compound, acting via DNA damage-induced S-phase arrest and mitochondrial-mediated apoptosis, and highlight its potential for further development as a liver cancer therapeutic.
