PH11
- CAS No.: 1627843-95-1
- Formula:C22H22N6O5
- Molecular Weight:450.45
IUPAC Name: methyl 2-((4-((3,4,5-trimethoxyphenyl)amino)imidazo[1,2-a][1,3,5]triazin-2-yl)amino)benzoate
InChIKey: HOGIPROMEUJZIJ-UHFFFAOYSA-N
SMILES: O=C(C1=C(NC2=NC3=NC=CN3C(NC4=CC(OC)=C(C(OC)=C4)OC)=N2)C=CC=C1)OC
Biological Activity: PH11 is a novel focal adhesion kinase (FAK) inhibitor that rapidly induces apoptosis in TRAIL-resistant PANC-1 cells when combined with TRAIL, but has no effect on normal human fibroblasts. The study found that PH11 downregulates c-FLIP through inhibition of FAK and phosphatidylinositol-3-kinase (PI3K)/AKT pathways, thereby restoring the TRAIL apoptotic pathway, suggesting that this combination therapy may provide an attractive therapeutic strategy for the safe and effective treatment of pancreatic cancer. PH11 selectively inhibits c-FLIP expression by modulating upstream signaling pathways and may represent an innovative therapeutic strategy. Although further work is needed to fully elucidate the mechanism of PH11-induced TRAIL sensitization, we believe that our results will provide a new approach to target c-FLIP without the risk of interfering with caspase-8 processing, which could potentially lead to TRAIL resistance. This study also suggests a role for the FAK/AKT signaling pathway in regulating c-FLIP expression in TRAIL-induced apoptosis, and this understanding will provide important clues to control the resistance mechanism to optimize the potential of TRAIL-based pancreatic cancer treatment.
