ZNF77 and cancer: Derivatization of Pt1 at either one or both axialhydroxyl positions can modulate the properties of this class of photoactivatableagents, introducing, for example, cancer-related receptor ligands,17,18 increased delivery to cancer cells,19−21 and hydrogel formulation.22 Conjugation to the axial hydroxide ligands canintroduce an additional payload and increase the efficacy of theseagents.
