Abstract
Multivalent carbohydrate-protein interactions are essential for many biological processes. Convenient characterization for multivalent binding property of proteins will aid the development of molecules to manipulate these processes. We exploited the polyproline helix II (PPII) structure as molecular scaffolds to adjust the distances between glycan ligand attachment sites at 9, 18, and 27 Å on a peptide scaffold. Optimized fluorous groups were also introduced to the peptide scaffold for immobilization to the microarray surface through fluorous interaction to control the orientation of the helical scaffolds. Using lectin LecA and antibody 2G12 as model proteins, the binding preference to the 27 Å glycopeptide scaffold, matched the distance of 26 Å between its two galactose binding sites on LecA and 31 Å spacing between oligomannose binding sites on 2G12, respectively. We further demonstrate this microarray system can aid the development of inhibitors by transforming the selected surface-bound scaffold into multivalent ligands in solution. This strategy can be extended to analyze proteins that lacking structural information to speed up the design of potent and selective multivalent ligands.

Abstract
Carboxyalkyl derivative of the intercalating agent imidazo[4,5-b]phenazine was used for the postsynthetic oligonucleotide modification. Model pentadecathymidylate-imidazophenazine conjugate was prepared from 5'-aminoalkyl-modified (dT)(15) by using phosphonium coupling reagent BOP in the presence of 1-hydroxybenzotriazole. Spectral-fluorescent properties of the conjugate were studied. The attachment of the dye was found to increase the thermal stability of (dT)(15) duplex with poly(dA) by more than 4°C, probably by the intercalation mechanism.

Abstract
Two diastereomeric series of hybrid γ,γ-peptides derived from conveniently protected derivatives of (1R,2S)- and (1S,2R)-3-amino-2,2-dimethylcyclobutane-1-carboxylic acid and cis-4-amino-L: -proline joined in alternation have efficiently been prepared through convergent synthesis. High-resolution NMR experiments show that these compounds present defined conformations in solution affording very compact structures as the result of intra and inter residue hydrogen-bonded ring formation. (R,S)-cyclobutane containing peptides adopt more twisted conformations than (S,R) diastereomers. In addition, all these γ-peptides have high tendency to aggregation providing vesicles of nanometric size, which were stable when allowed to stand for several days, as verified by transmission electron microscopy.

Abstract
The synthesis of new substituted prolines carrying at C-4 a second alpha-amino acid residue is reported. The amino acid, L-cysteine or L-selenocysteine, is linked to the proline ring through the sulfur or the selenium atom, respectively. The products were prepared with different stereochemistry at C-4, in few and clean high-yielding steps, with suitable protections for solid phase applications. The introduction of both sulfur and selenium atoms at C-4 of the proline ring seems to enhance significantly the cis geometry at the prolyl amide bond.
