Harringtonolide is a potent RACK1 inhibitor (IC50=39.66 μM in A375 cells). Harringtonolide inhibits the epithelial-mesenchymal transition (EMT) process and cell proliferation by affecting the interaction between FAK and RACK1. Harringtonolide has plant growth inhibitory, antiviral, anti-inflammatory, and antiproliferation activities[1].
Harringtonolide (0-50 μM; 24 hours) exhibits good antiproliferation activity in A375 cells with IC50 of 39.66 μM[1].
Harringtonolide (0-20 μM; 1 hour) restrains the proteolysis of RACK1 by Pronase, and protects temperature-dependent degradation of RACK1[1].
Harringtonolide (0-4 μM; 24 hours) suppresses the phosphorylation of FAK dose-dependently and inhibits Src and STAT3, the downstream proteins of FAK[1].
Harringtonolide (0-4 μM; 24 hours) dose-dependently inhibits the RACK1–FAK interaction in A375 cells[1].
