Mean of compounds from four biological replicates. All the compounds were added after 3h of reverse co‐transfection and used at the final concentration of 5 µM for approximately 30 h. Mean of DMSO from 64 biological replicates (32 replicates per each 384‐well plate). Data are reported as Z‐score values.
