Effective inhibitors of cancer cell migration and invasion can potentially lead to clinical applications as a therapy to block tumor metastasis, the primary cause of death in cancer patients. To this end, we have designed and synthesized a series of thiazole derivatives that showed potent efficacy against cell migration and invasion in metastatic cancer cells. The most effective compound, 5k, was found to have an IC50 value of 176 nM in the dose-dependent transwell migration assays in MDA-MB-231cells. At a dose of 10 μM, 5k also blocked about 80% of migration in HeLa and A549 cells and 60% of invasion of MDA-MB-231 cells. Importantly, the majority of the derivatives exhibited no apparent cytotoxicity in the clonogenic assays. The low to negligible inhibition of cell proliferation is a desirable property of these antimigration derivatives because they hold promise of low toxicity to healthy cells as potential therapeutic agents. Mechanistic studies analyzing the actin cytoskeleton by microscopy demonstrate that compound 5k substantially reduced cellular f-actin and prevented localization of fascin to actin-rich membrane protrusions. These results suggest that the antimigration activity may result from impaired actin structures in protrusions that are necessary to drive migration.
