  • Substituted spirooxindoles
    Patent number: 9822128
    Abstract: The substituted spirooxindoles are MDM2-p53 inhibitors bearing a benzylidine (styryl) arm and have a complex fused ring system ideally suited for binding to the MDM2 protein, thereby interrupting its protein-protein interaction (PPI). Sixteen compounds, designated 4a-4p, were synthesized in a simple smooth method using an asymmetric 1,3-dipolar reaction as the key step. Testing showed that the compounds exhibit anti-cancer activity against various forms of cancer cells affecting humans.
