Novel 1,2,3-triazole-based compound triggers apoptosis through DNA damage response involving ATM/ATR signaling in liver cancer cells. (PubMed, Biochem Pharmacol)
1,2,3-Triazole-substituted cabotegravir analogues, i.e., KJ-9, have been developed as lead structures to explore their potential as antitumor agents. After KJ-9 treatment, ROS were suppressed by the addition of the antioxidant N-Acetylcysteine (NAC), leading to increased levels of p-AKT and reduced levels of p-ATM, p-ATR, p-p53, cleaved caspase-3, and γ-H2AX. These findings suggest that KJ-9 promotes oxidative stress, which further inhibits AKT activation while activating the ATM/ATR pathway, leading to p53 accumulation, sustained DNA damage responses, G2/M-phase cell cycle arrest, and apoptosis in both HepG2 cells and HCCLM3 cells.
