(antigen)-NC41 (antibody) complex to design a low molecular weight compound that mimics the binding function of the macromolecular antibody. The components of recognition between the antibody and the protein antigen have been analyzed from the energy-refined crystal complex. From this analysis, four amino acid residues on the antibody binding surface, which make direct contact with the active-site loop 368-370

In the field of peptide synthesis, the key to a successful access to synthetic targets lies on a pertinent combination of protectinggroups. Their choice is directed by their selective removal conditions. We present here the behavior of some of the most usedprotectinggroups in peptide chemistry under experimental cleavage conditions, combining MgI2 with MW irradiation, using 2‐Me‐THF as a green solvent

The cyclic peptide 1, containing a 2,7-disubstituted naphthalene spacer, was designed to mimic an exposed Ω-loop present in interleukin-1α, an important mediator of immune and inflammatory responses. The synthesis of this cyclic peptide was accomplished via solution phase fragment condensation methodology. The three dimensional characterization using 2D-NMR techniques revealed it to be an excellent
