JI051 is a stabilizer for the Hes1-PHB2 interaction, interacts with a cancer-associated protein chaperone prohibitin 2 (PHB2), induces cell-cycle arrest by inhibiting the Notch downstream effector gene Hes1. Anti-cancer activity[1].
JI051 causes G2/M cell-cycle arrest[1].JI051 (0.1-10 µM, 24 hours) significantly inhibits cell proliferation of HEK293 cells, with an EC50 of 0.3 μM[1]. Cell Proliferation Assay[1] Cell Line: HEK293 cells
