Natural product-inspired [3 + 2] cycloaddition-based spirooxindoles as dual anticancer agents: synthesis, characterization, and biological evaluation by in vitro and in silico methods†

Abstract

Breast and colorectal cancers are the most common tumors, with high recurrence and low survival rates. We designed and synthesized a series of spirooxindole pyrrolidinyl derivatives, which were further evaluated for anti-proliferative activity using MDA-MB-468 and HCT 15 cell lines. The best inhibitor of this class, compound 6f, showed a very good inhibition potency, both on the MDA-MB-468 and HCT 15 cells as confirmed by molecular docking and molecular dynamic studies that predicted its binding mode into the active site of the targets. In summary, this study provided a new anti-proliferative derivative 6f which is worthy of further research.
