PI3Kα/HDAC6-IN-1

PI3Kα/HDAC6-IN-1 (compound 21j) is a dual inhibitor of PI3Kα and HDAC6, with IC50 values of 2.9 nM and 26 nM, respectively. It hinders AKT (Ser473) phosphorylation and promotes the accumulation of acetylated α-tubulin without affecting acetylated histones H3 and H4. The compound exhibits potent anti-cancer efficacy, inhibiting the L-363 cell line with an IC50 of 0.17 μM [1].
