Synthesis, structural characterization and anion binding studies of palladium macrocycles with hydrogen-bonding ligands.
The reactions between [Pd(P-P)(OTf)2] (where P-P=dppp or dppf) and two different bipyridyl ligands (=1,3-bis(4-pyridylmethyl)urea and=1,3- bis(pyridinylmethyl)benzenedicarboxamide) containing hydrogen-bonding units have been studied. The X-ray crystal structures of three of these assemblies have been solved showing them to be the [2+2] metallo-macrocycles [Pd(P-P)(n)]2(OTf)4 [P-P=dppp, n=1, ();...
متن کاملAcylthioureas as anion transporters: the effect of intramolecular hydrogen bonding.
Small molecule synthetic anion transporters may have potential application as therapeutic agents for the treatment of diseases including cystic fibrosis and cancer. Understanding the factors that can dictate the anion transport activity of such transporters is a crucial step towards their application in biological systems. In this study a series of acylthiourea anion transporters were synthesis...
متن کاملBinding biomolecules with designed, hydrogen- bonding receptors
An approach to the design of artificial receptors is described involving the fusion of several sixmembered rings, preorganizing nitrogen and oxygen hydrogen bonding sites. A hexagonal lattice chemosensor extracts the blood metabolite creatinine into water and acts as a chromogenic reagent for this clinical analyte. Another receptor binds urea via six hydrogen bonds, forming a complex that is st...
متن کاملHydrogen Bonding Penalty upon Ligand Binding
Ligand binding involves breakage of hydrogen bonds with water molecules and formation of new hydrogen bonds between protein and ligand. In this work, the change of hydrogen bonding energy in the binding process, namely hydrogen bonding penalty, is evaluated with a new method. The hydrogen bonding penalty can not only be used to filter unrealistic poses in docking, but also improve the accuracy ...
متن کاملVery long-range effects: cooperativity between anion-pi and hydrogen-bonding interactions.
The interplay between two important non-covalent interactions involving aromatic rings (namely anion-pi and hydrogen bonding) is investigated. Very interesting cooperativity effects are present in complexes where anion-pi and hydrogen bonding interactions coexist. These effects are found in systems where the distance between the anion and the hydrogen-bond donor/acceptor molecule is as long as ...
