Trigeminal star-like platinum complexes induce cancer cell senescence through quadruplex-mediated telomere dysfunction†
Abstract
Two trigeminal star-like platinum complexes were synthesized to induce the formation of human telomere G-quadruplex (hTel G4) with extremely high selectivity and affinity. The induced hTel G4 activates strong telomeric DNA damage response (TDDR), resulting in telomere dysfunction and cell senescence.
