The clinical benefit of combination therapy is significant,but it is not easy to define the mechanism of complexity and diversity.Previous studies illustrate that phillygenin(Phi)binds in the allosteric inhibit pocket of protein kinase B(AKT),and swertiamarin(Swe)acts on the pleckstrin homology(PH)domain of AKT.However,the combined synergistic effect of relieving the inflammatory response has yet to be elucidated.Based on high sensitivity,specificity and fast-responsibility fluorescent sensors,the Förster resonance energy transfer(FRET)technique offers a route to provide clear insights into physiological and pathological processes.In the study,molecular docking,the fluorescent probes of Phi and Swe for FRET were designed and synthesized.FRET analysis shown that Swe and Phi concurrently acted on the PH do-main and allosterically inhibited pocket of AKT,respectively.The combination of Swe and Phi significantly increased the heat stability of AKT and decreased protease-induced degeneration.In lipopolysaccharides(LPS)-induced mice and cells,the combination arrested AKT activation,nuclear factor kappa-B(NF-κB)phosphorylation,and the expression of tumor necrosis factor-α(TNF-α),interleukin(IL)-6 and IL-8.In conclusion,FRET revealed Phi and Swe concurrently targeted AKT on different domains and the combi-nation of Phi and Swe enhanced the anti-inflammatory effect.
