## Title
1-substituted pyrrolidin-2-ones and use thereof as peptide deformylase inhibitors

## Abstract

The present invention relates to compounds of formula (I).




These compounds are a novel type of peptide deformylase (PDF) inhibitors, and are therefore of great interest especially as new antibiotics.

## Background
This application is a U.S. National Phase filing of PCT/EP2006/005369 filed Jun. 6, 2006, the contents of which are incorporated herein by reference.
The present invention relates to new inhibitors of peptide deformylase (PDF). These compounds are of great interest in particular as antibiotics.
Peptide deformylase is a bacterial metalloenzyme which contains iron. It is detectable in all bacteria and plays a vital role in bacterial metabolism. During protein synthesis, peptide deformylase catalyses the removal of the formyl group from the N-terminus of bacterial proteins. Without the enzyme, bacteria cannot produce any functioning proteins. Peptide deformylase is the point of application of a new class of antibiotics, which are called peptide deformylase inhibitors.
It is the aim of the present invention to prepare new inhibitors of peptide deformylase that are obtainable synthetically in a simple manner.
The present invention relates to compounds of formula (I),

The pharmaceutical compositions according to the present invention contain at least one compound of formula (I) as active ingredient and optionally carriers and/or adjuvants.
The prodrugs (e.g. R. B.

Compounds of formula (I) are of great interest, according to the invention, especially as inhibitors of metalloproteinases (in particular PDF). The usage of these active ingredients in the production of medicaments to prevent and/or treat diseases, especially those conveyed by PDF, is also an object of the present invention. In general, compounds of formula (I) are administered using known, acceptable methods, either singly or in combination with any other therapeutic agent. Administration may be effected e.g. in one of the following ways: orally, e.g. as dragées, coated tablets, pills, semi-solids, soft or hard capsules, solutions, emulsions or suspensions; parenterally, e.g. as an injectable solution; rectally as suppositories; by inhalation, e.g. as a powder formulation or spray, transdermally or intra-nasally. To produce such tablets, pills, semi-solids, coated tablets, dragées and hard gelatin capsules, the therapeutically employable product may be mixed with pharmacologically inert, inorganic or organic carriers for medicaments, e.g. with lactose, sucrose, glucose, gelatin, malt, silica gel, starch or derivatives thereof, talc, stearic acid or salts thereof, dry skimmed milk and the like. To produce soft capsules, carriers for medicaments, such as vegetable oils, petroleum, animal or synthetic oils, wax, fat, polyols, may be used. To produce liquid solutions and syrups, carriers for medicaments, such as water, alcohols, aqueous salt solution, aqueous dextrose, polyols, glycerol, vegetable oils, petroleum, animal or synthetic oils, may be used. For suppositories, carriers for medicaments, such as vegetable oils, petroleum, animal or synthetic oils, wax, fat and polyols, may be used. For aerosol formulations, compressed gases that are appropriate for this purpose may be used, such as oxygen, nitrogen and carbon dioxide. The pharmaceutically acceptable agents may also contain preserving and stabilizing additives, emulsifiers, sweeteners, aromatics, salts to modify the osmotic pressure, buffers, coating additives and antioxidants.
Compounds of formula (I) may be produced by reacting compounds of formulae X—[CR1R2]n—NH2 (II), R3—CO—R4 (III) and R5—CH2—CO—COOEt (IV), whereby the radicals are defined as above.


EXAMPLES
General Procedure:
50 μl of a 0.2 M solution of amine (II) in ethanol:dichloromethane (1:1) were dispensed onto a 96-well plate. 50 μl of a 0.2 M solution of the aldehyde (R3=H) or ketone (III) in ethanol:dichloromethane (1:1) were added. The plate was shaken for 20 mins at room temperature. Subsequently, 50 μl of a 0.2 M solution of the keto acid (IV) in ethanol:dichloromethane (1:1) were dispensed. The plate was shaken over night at room temperature and the solvent subsequently evaporated.
The following compounds were produced in accordance with the general procedure, using appropriate starting materials, and were identified by mass spectrometry. All compounds were investigated for their activity as PDF inhibitors (for the assay, see D. Chen et al. Antimicrobial Agents and Chemotherapy, January 2004, pp. 250-261) and had IC50 values ranging between 1 nmol and 50 μmol.
