The synthesis, the enantiomeric separation, and the characterization of new simple spiroketal derivatives have been performed. The synthesized compounds have shown a very high anticancer activity. Cell proliferation assay showed that they induce a remarkable inhibition of cell proliferation in all cell lines treated, depending on culture time and concentration. The compounds have also shown a potent nanomolar human telomerase inhibition activity and apoptosis induction. CD melting experiments demonstrate that spiroketal does not affect the G-quadruplex (G4) thermal stability. Docking studies showed that telomerase inhibition could be determined by a spiroketal interaction with the telomerase enzyme.
