AG-1296

Interventions utilizing a range of inhibitors at the in vitro level, including the PDGFR-β inhibitor AG1296, the PI3K inhibitor LY294002, the AKT inhibitor MK2206, and the FAK inhibitor Y15, demonstrated that E. multilocularis protoscoleces protein (EmP) induces angiogenesis through PDGFR/PI3K/AKT/FAK signaling pathway. Our findings provide new perspectives on how E. multilocularis infection triggers pathological angiogenesis in the host liver, and may provide a novel anti-angiogenic therapeutic strategy against E. multilocularis infection.

With inhibition of PDGFRα and PDGFRβ using AG1295 or AG1296, VM formation in gastric cancer cells decreased (P <0.05), but the number of VM structures increased while LOX was added (P < 0.05). LOX partially promotes the formation of VM in gastric cancer through the PDGF-PDGFR signaling pathway.

To conclude, tyrphostin AG1296 is a promising compound in the treatment of alveolar RMS. Undoubtedly, a better knowledge of receptor pathomechanism of tyrosine kinases may contribute to developing new, more effective ways of RMS treatment.
