The conformationally restricted, spatially defined macrocyclic ring system of formula (I) is constituted by three distinct molecular parts: Template A, conformation Modulator B and Bridge C. Macrocycles described by this ring system I are readily manufactured by parallel synthesis or combinatorial chemistry in solution or on solid phase. They are designed to interact with a variety of specific biological target classes, examples being agonistic or antagonistic activity on G-protein coupled receptors (GPCRs), inhibitory activity on enzymes or antimicrobial activity. In particular, these macrocycles show inhibitory activity on endothelin converting enzyme of subtype 1 (ECE-1) and/or the cysteine protease cathepsin S (CatS), and/or act as antagonists of the oxytocin (OT) receptor, thyrotropin-releasing hormone (TRH) receptor and/or leukotriene B4 (LTB4) receptor, and/or as agonists of the bombesin 3 (BB3) receptor, and/or show antimicrobial activity against at least one bacterial strain. Thus they are showing great potential as medicaments for a variety of diseases.

first total synthesis of YM-280193, a cyclic depsipeptide that inhibits the ADP-induced aggregation of human platelets, is described. The monomer and dipeptide fragments were prepared using conventional chemistry and subsequently assembled by Fmoc-solid-phase peptide synthesis (Fmoc-SPPS). A late-stage novel bis-alkylation–elimination of cysteine on-resin was employed to introduce the unnatural N-methyldehydroalanine

The present invention provides compounds and pharmaceutical compositions for inhibiting N-acylethanolamine acid amidase (NAAA). Inhibition of NAAA is contemplated as a method to sustain the levels of palmitoylethanolamide (PEA) and oleylethanolamide (OEA), two substrates of NAAA, in conditions characterized by reduced concentrations of PEA and OEA. The invention also provides methods for treating inflammatory diseases and pain, and other disorders in which decreased levels of PEA and OEA are associated with the disorder.

identified unique features in the macrocyclic structures responsible for binding to the target protein correlating with inhibitory activity. While all novel compounds were devoid of effects on Gi and Gs proteins, no inhibitor surpassed the biologicalactivity of FR. This raises the question of whether depsipeptides such as FR already represent valuable chemical tools for specific inhibition of Gq and, at
