چکیده

Single crystal X-ray diffraction studies on the water soluble, synthetic tetrapeptide Tyr(1)-Aib(2)-Tyr(3)-Val(4) with a non-coded amino acid residue (Aib: [small alpha]-amino isobutyric acid) reveal that the peptide adopts an "S"-shaped molecular structure which self-assembles to form a supramolecular triple helix using various non-covalent interactions including water mediated hydrogen bonds in the solid state.

Evidences for supramolecular organization of nucleopeptides: synthesis, spectroscopic and biological studies of a novel dithymine L-serine tetrapeptide.

This work concerns a dithymine tetrapeptide, which can be seen as a new analogue of a dinucleoside monophosphate, made of both unfunctionalized and thymine-containing L-serine units alternated in the sequence. The new nucleopeptide was obtained on the solid phase by two different synthetic strategies. The first one is suitable to easily realize nucleopeptides with homonucleobase sequences, obta...

Surface-grafted Europium and Erbium Complexes of the 12-Tungstosilicate Heteropolyoxometalate: A Synthetic and Structural Investigations

The hydrothermal synthesis of two new inorganic-organic hybrid materials in which PDA (PDA = 1,10-phenanthroline-2,9-dicarboxylate) is connected to a well-defined Keggin-type polyoxometalate anion (POM) and a Ln(III) cation (POM = [SiW12O40]4−; Ln = Eu3+ (1), Er3+ (2)), are reported. These hybrids are characterized by elemental analyses, IR spectra and single-crystal X-ray diffraction. Single-c...

Facile resolution of racemic terbutaline and a study of molecular recognition through chiral supramolecules based on enantiodifferentiating self-assembly.

An effective resolving agent, (2S, 3S)-di-O-(p-toluoyl) tartaric acid(4), was screened using a 'family' approach to yield direct resolution of (R)-terbutaline (1) with high optical purity and yield. Molecular recognition was studied by X-ray crystallographic analyses of the single crystals of the pair of diastereomeric salts. The more-soluble salt formed a sheet supramolecular structure, and th...

A water soluble and air-stable tripalladium cluster.

Complexation of 2,7-dipyridin-2-ylnaphthyridine (bpnp) with a mixture of (PhCN)(2)PdCl(2) and Pd(2)(dba)(3) resulted in the formation of a water soluble and air-stable tripalladium cluster [Pd(3)(bpnp)(2)Cl(2)]Cl(2), which was characterized by NMR spectroscopic and X-ray crystallographic analyses.
