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
