Using Chemistry to Target Neuroblastoma

Neuroblastoma is a cancer of the neural crest almost exclusively seen in childhood. While children with single, small primary tumors are often cured with surgery alone, the 65% of children with neuroblastoma whose disease has metastasized have less than a 50% chance of surviving five years after diagnosis. Innovative pharmacological strategies are critically needed for these children. Efforts to identify novel targets that afford ablation of neuroblastoma with minimal toxicity to normal tissues are underway. Developing approaches to neuroblastoma include those that target the catecholamine transporter, ubiquitin E3 ligase, the ganglioside GD2, the retinoic acid receptor, the protein kinases ALK and Aurora, and protein arginine N-methyltransferases. Here, as examples of the use of chemistry to combat neuroblastoma, we describe targeting of the protein arginine N-methyltransferases and their role in prolonging the half-life of the neuroblastoma oncoprotein N-Myc, redox signaling in neuroblastoma, and develo...
