Biological Activity
Perhexiline maleate is a potent carnitine palmitoyltransferase 1 (CPT 1) inhibitor with IC50s of 77 and 148 μM for rat heart and liver CPT 1, respectively.
In Vitro
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[2].
In Vivo
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[2].
Target
IC50: 77 μM (Rat heart CPT 1), 148 μM (Rat liver CPT 1)[1]
Cell Assay
The effect of antitumoral drugs on neuroblastoma cell survival is evaluated using the MTT assay. Approximately 24 hours after plating, cells are exposed to Perhexiline maleate (0.01 μM) for 48 hours at 37°C. Cytotoxicity is expressed as the percentage of cells surviving in relation to untreated cells[2].
Animal Administration
Mice: In protocol a, 21 mice are divided in 4 groups: control vehicle group: DMSO; cisplatin (3 mg/kg/dose) treated group; Perhexiline (1 mg/kg/dose) treated group and; Perhexiline (1 mg/kg/dose) and cisplatin (3 mg/kg/dose) treated group. In protocol b, 20 mice are divided in 4 groups: control vehicle group: DMSO; Perhexiline (3 mg/kg/dose) treated group; cisplatin (5 mg/kg/dose) treated group; Perhexiline (3 mg/kg/dose) and cisplatin (5 mg/kg/dose) treated group[2].
