Synthesis and evaluation of RGD peptidomimetics aimed at surface bioderivatization of polymer substrates
摘要:
Several RGD peptidomimetics have been prepared, in a convergent way, from the common ortho-amino-tyrosine template (O-substituted with an anchorage-arm or a methyl group, and alpha N-substituted with a fluorine tag for XPS analysis), and various omega-aminoacid derivatives. The most flexible compounds have shown a biological activity similar to that of the peptide reference (RGDS) in the platelet aggregation test. The compound 16a could be fitted (by modelisation) with DMP 728 and c(RGDfV), two cyclic peptides that are good ligands of integrins. The compound 16b has been covalently fixed on the surface of a poly(ethylene terephthalate) membrane used as support for mammalian cell cultivation. (C) 1998 Elsevier Science Ltd.

Glucose-responsive insulin conjugates that contain one or more trisaccharides are provided. Such insulin conjugates may display a pharmacokinetic (PK) and/or pharmacodynamic (PD) profile that is responsive to the systemic concentrations of a saccharide such as glucose or alpha-methylmannose, even when administered to a subject in need thereof in the absence of an exogenous multivalent saccharide-binding molecule.

acid with relatively shorter side-chain methylenes. The dye specificity in terms of induction of the intense fluorescence was also investigated using hemicyanines (stilbazoliumetc.), cyanine, carbocyanine, thiacarbocyanines, and azo dye. The amphiphile with the shortest octanoyl-β-alanyl double-chain alkyl groups, longer side-chain, and shorter spacer was found to show increased sensitivity to alkali
A systematic understanding of gelation self-assembly: solvophobically assisted supramolecular gelation via conformational reorientation across amide functionality on a hydrophobically modulated dipeptide based ambidextrous gelator, N-n-acyl-(<scp>l</scp>)Val-X(OBn), (X = 1,ω-amino acid)

Gelator backbone conformational flexibility plays an important role in a supramolecular self-assembly which is synergistically assisted by solvophobic interaction leading to a gelation of three sets of hydrophobically modulated dipeptidic gelators.
