  Evaluation of Multisite Polypyridyl Ligands as Platforms for the Synthesis of Rh/Zn, Rh/Pd, and Rh/Pt Heterometallic Complexes

  摘要：

  Ligands containing linked dipicolylamine (dpa) and bipyridine (bpy) sites have been utilized in the synthesis of monometallic and heterometallic complexes. The two sites have different selectivities for metal binding, which allows preferential formation of singly metalated complexes. The dpa site of the ligands has been observed to bind selectively to Zn2+, Pd2+, and Pt2+, while the bpy site binds selectively to Rh+. Addition of a second metal then results in the formation of heterometallic products. In the presence of CD3OD, the heterometallic Rh/Pt and Rh/Pd complexes undergo rapid selective H/D exchange of one of the diastereotopic protons of the dpa methylene group.

  the research field of molecular recognition, selective recognition and sensing of phosphorylated protein surfaces is strongly desirable both for elucidation of protein-protein recognition at the molecular level and for regulation of signal transduction through protein surfaces. Here we describe a new strategy for molecular recognition of a multi-phosphorylated peptide using intrapeptide cross-linking

  Ligands containing linked dipicolylamine (dpa) and bipyridine sites have been explored as platforms for the synthesis of heterometallic complexes containing the paramagnetic metals Cu2+ and Co2+. IR and EPR studies on the bimetallic complexes and simplified model compounds support dpa-selective binding by both of these metals. The IR spectra have also been compared to those of diamagnetic Rh+, Zn2+

  Protein phosphorylation is ubiquitously involved in living cells, and it is one of the key events controlling protein-protein surface interactions, which are essential in signal transduction cascades. We now report that the small molecular receptors bearing binuclear Zn(ll)-Dpa can strongly bind to a bisphosphorylated peptide in a cross-linking manner under neutral aqueous conditions when the distance between the two Zn(ll) centers can appropriately fit in that of the two phosphate groups of the phosphorylated peptide. The binding property was quantitatively determined by ITC (isothermal titration calorimetry), induced CD (circular dichroism), and NMR. On the basis of these findings, we demonstrated that these types of small molecules were able to effectively disrupt the phosphoprotein-protein interaction in a phosphorylated CTD peptide and the Pin1 WW domain, a phosphoprotein binding domain, at a micromolar level. The strategy based on a small molecular disruptor that directly interacts with phosphoprotein is unique and should be promising in developing a designer inhibitor for phosphoprotein-protein interaction.
