When the mean natural log EC50 values of LIMKi for these 6 cell lines were compared to CRT0105950 and CRT0105446 EC50 values for the 27 neuroblastoma cell lines from the screen, both LIMKi and CRT0105950 were significantly more effective than CRT0105446 but were not different from each other (Figure 10B), consistent with their rank order of potencies for inhibition of cofilin phosphorylation, tubulin acetylation and matrix invasion (Figure 7). Here, CFL1 is linked to neuroblastoma.
