Neuroblastoma (NB), the most common extracranial malignant childhood tumor accounts for about 15% of cancer-related deaths in children. Despite the intensive treatment of patients with high-risk scarification of NB, clinical outcomes indicate tumor recurrence greater than 50% and late severe adverse effects. Oxazolidinones are 5-membered heterocyclic compounds with antibacterial activity against resistant bacterial strains. Structural modifications around the oxazolidinone moiety have resulted in derivatives with anti-cancer properties against proliferation, motility, and invasion of breast cancer cells. This study aimed to examine the anti-cancer potential of novel oxazolidinones against a model of a neuroblastoma cell line. Newly synthesized and characterized triazolyl-oxazolidinone derivatives were incubated with neuroblastoma Kelly cells. The anti-proliferation and anti-progression effects of the compounds were evaluated by MTT, and adhesion with migration assays. The 5-nitrofuroyl glycinyl-oxazolidinone containing 4-methyltriazolyl group demonstrated the most potent activity with an IC50=6.52 μM. Furthermore, the D-isomer of 5-nitrothiophenecarbonyl alaninyl containing derivative reduced the adhesion to fibronectin by 56.34%, while the D-isomer of 5-nitrofuroyl alaninyl derivative reduced the migration of Kelly cells by 29.14%. The presence of the 4-methyltriazolyl moiety seems to enhance the anti-proliferative property of triazolyl-oxazolidinone derivatives, as demonstrated by PH-145. There is little or no effect of the stereochemistry of the alanine side-chain on the antiproliferative effect, as demonstrated by the 5-nitrofuroyl D- and L-alaninyl containing derivatives with similar IC50 values. The observed differences in the inhibition of adhesion and migration by the oxazolidinones on Kelly cells provide a new therapeutic approach that needs further investigation.
