Starting from pyroglutamic acid, 4‐substituted‐5‐vinylprolines were stereoselectively prepared and used as building blocks for the synthesis of conformationally well‐defined diproline analogs, which are of interest as proline‐derived modules (ProMs) for the construction of PPII‐helix secondary‐structure mimetics acting as inhibitors of relevant protein‐protein interactions.
A practical and scalable synthesis of a Fmoc‐protected tricyclic dipeptide mimetic (6), that is, a 1,4‐diaza‐tricyclo‐[8.3.03, 7]‐tridec‐8‐ene derivative resembling a rigidified di‐L‐proline in a polyproline type II (PPII) helixconformation, was developed. The strategy is based on a Ru‐catalyzed ring‐closing metathesis of a dipeptide (4) prepared by PyBOP coupling of cis‐5‐vinylproline tert‐butylester

The invention relates to compounds of general formula (I), which can be used particularly as structural mimetics of proline-rich peptides and are therefore capable of binding PRM binding domains (proline-rich motif binding domains) of proteins. The invention also relates to the use of said compounds as pharmaceutical active agents and the use of these pharmaceutical active agents for treating bacterial diseases, neurodegenerative diseases and tumours.
The present invention relates to chemical compounds that can in particular be used as structural mimetics of proline-rich peptides. The compounds of the present invention are capable of selectively inhibiting ena/VASP-EVH1-mediated protein-protein interactions. The invention further relates to the use of said compounds as pharmaceutical agents and to the use of the pharmaceutical agents to treat tumor diseases. The chemical compounds of the present invention can significantly inhibit the chemotaxis and motility of invasive tumor cells and can therefore be used in the treatment and/or prevention of tumor metastases.

The invention relates to compounds that can be used, in particular, as structural mimetics of proline-rich peptides and are correspondingly able to bond with proline-rich-motif binding domains (PRM domains) of proteins. The invention further relates to the use of these compounds as pharmaceutically active agents, as well as the use of the pharmaceutically active agents for the treatment of bacterial, neurodegenerative and tumor diseases.
