Purpose: This study aimed to investigate the efficiency of our chemically synthesized TT-00420, a novel spectrum-selective multiple protein kinase inhibitor, in cultured cells and animal models of gallbladder Cancer (GBC) and explore its potential mechanism.
Methods: Multiple GBC models were established to assess the anti-tumor efficiency, toxicity, and pharmacokinetics of TT-00420. Integrated transcriptomic, proteomic and phosphoproteomic analysis was conducted to identify potential downstream effectors of TT-00420. Western blotting, qRT-PCR, nuclear-cytoplasm separation, and immunofluorescence were performed to confirm the multi-omic results and explore the molecular mechanism of TT-00420. Immunohistochemistry was used to detect FGFR1 and p-FGFR1 expression levels in GBC samples. Autodock software was utilized to investigate the potential binding mode between the TT-00420 and the human FGFR1.
Results: We found that TT-00420 exerted potent growth inhibition of GBC cell lines and multiple xenograft models. Treatment of mice with 15 mg/kg TT-00420 via gavage displayed a half-life of 1.8 h in the blood and rapid distribution to the liver, kidneys, lungs, spleen, and tumors at 0.25 h, but no toxicity to these organs over 2 weeks. Multi-omic analysis revealed c-Jun as a potential downstream effector after TT-00420 treatment. Mechanistically, TT-00420 showed rigorous ability to block FGFR1 and its downstream JNK-JUN (S63/S73) signaling pathway, and induce c-Jun S243-dependent MEK/ERK reactivation, leading to FASLG-dependent tumor cell death. Finally, we found that FGFR1 and p-FGFR1 expression was elevated in GBC patients and these levels correlated with decreased patient survival.
Conclusions: TT-00420 shows potent antitumor efficacy and may serve as a novel agent to improve GBC prognosis.
