At 24, 48 and 72 h of treatment with 0.01 and 1 μM of Perhexiline , NDM29 ncRNA expression level in SH-SY5Y cells is progressively increased, reaching a peak after 48 hours of treatment. Perhexiline treatment increases the susceptibility of NB cells to antiblastic treatments. Co-administration of Perhexiline maleate potentiates the efficacy of cisplatin to reduce the in vitro clonogenic potential of NB cells.

The co-administration of Perhexiline and cisplatin yields a clear enhancement of antitumor effects, resulting in a significantly improved progression-free survival as compared with mice treated with DMSO. Perhexiline favors NB cell transition to differentiated phenotype.
