Mechanistic studies of the anticancer activity of an octahedral hexanuclear Pt(II) cage
The cellular response evoked by a hexanuclear platinum complex, Pt6L4(1), is reported. Compound 1, a 3-nm octahedral cage formed by self-assembly of six Pt(II) centers and four 2,4,6-tris(4-pyridyl)-1,3,5-triazine ligands (L), exhibits promising in vitro potency against a panel of human cancer cell...

Summary: | The cellular response evoked by a hexanuclear platinum complex, Pt6L4(1), is reported. Compound 1, a 3-nm octahedral cage formed by self-assembly of six Pt(II) centers and four 2,4,6-tris(4-pyridyl)-1,3,5-triazine ligands (L), exhibits promising in vitro potency against a panel of human cancer cell lines. Unlike classical platinum-based anticancer agents, 1 interacts with DNA in a non-covalent, intercalative manner and promotes DNA condensation. In cancer cells, 1 induces DNA damage, upregulates p53, its phosphorylated form phospho-p53 and its downstream effector, p21, as well as both apoptosis and senescence.
