Abstract

The present invention relates to novel amide derivatives of N-urea substituted amino acids, processes for preparing them, pharmaceutical compositions containing them and their use as pharmaceuticals as modulators of the N-formyl peptide receptor like-1 (FPRL-1) receptor.

First claim

What is claimed is:

1. A method of treating rheumatoid arthritis in a subject in need of such treatment, the method comprising administering to the subject a therapeutically effective amount of a compound of Formula II:

wherein:
a is 1 and b is 0;
R 1 is optionally substituted C 1-8 alkyl, optionally substituted C 3-8 cycloalkyl, optionally substituted heterocycle, optionally substituted C 6-10 aryl, optionally substituted C 3-8 cycloalkenyl, —NR 11 R 12 or
—OR 13 ;

R 2 is optionally substituted C 1-8 alkyl or optionally substituted C 6-10 aryl;
R 3 is hydrogen, optionally substituted C 1-8 alkyl, halogen, —COOR 15 , —OR 13 , —NR 11 R 12 , NO 2 , optionally substituted heterocycle, optionally substituted C 3-8 cycloalkyl, optionally substituted C 6-10 aryl or optionally substituted C 3-8 cycloalkenyl;
R 4 is hydrogen, optionally substituted C 1-8 alkyl, halogen, —COOR 15 , —OR 13 , —NR 11 R 12 , NO 2 , optionally substituted heterocycle, optionally substituted C 3-8 cycloalkyl, optionally substituted C 6-10 aryl or optionally substituted C 3-8 cycloalkenyl;
R 5 is halogen;
R 6 is hydrogen, optionally substituted C 1-8 alkyl, halogen, —COOR 15 , —OR 13 , —NR 11 R 12 , NO 2 , optionally substituted heterocycle, optionally substituted C 3-8 cycloalkyl, optionally substituted C 6-10 aryl or optionally substituted C 3-8 cycloalkenyl;
R 7 is hydrogen, optionally substituted C 1-8 alkyl, halogen, —COOR 15 , —OR 13 , —NR 11 R 12 , NO 2 , optionally substituted heterocycle, optionally substituted C 3-8 cycloalkyl, optionally substituted C 6-10 aryl or optionally substituted C 3-8 cycloalkenyl;
R 8 is hydrogen, optionally substituted C 1-8 alkyl or optionally substituted C 6-10 aryl;
R 9 is hydrogen;
R 10 is hydrogen;
R 11 is hydrogen or optionally substituted C 1-8 alkyl, provided that R 11 is not

R 12 is hydrogen;
R 13 is hydrogen or optionally substituted C 1-8 alkyl; and
R 15 is hydrogen or optionally substituted C 1-8 alkyl;
or an enantiomer, diastereomer, tautomer, hydrate or solvate thereof;
or a pharmaceutically acceptable salt of the foregoing;
provided that the compound is not:

2. The method of claim 1 , wherein:
R 1 is optionally substituted C 1-8 alkyl, —NR 11 R 12 or —OR 13 ;
R 2 is optionally substituted C 1-8 alkyl;
R 3 is hydrogen, optionally substituted C 1-8 alkyl, halogen, —COOR 15 , —OR 13 or —NR 11 R 12 ;
R 4 is hydrogen, optionally substituted C 1-8 alkyl, halogen, —COOR 15 , —OR 13 or —NR 11 R 12 ;
R 6 is hydrogen, optionally substituted C 1-8 alkyl, halogen, —COOR 15 , —OR 13 or —NR 11 R 12 ;
R 7 is hydrogen, optionally substituted C 1-8 alkyl, halogen, —COOR 15 , —OR 13 or —NR 11 R 12 ; and
R 8 is hydrogen or optionally substituted C 1-8 alkyl.

3. The method of claim 2 , wherein:
R 1 is —OR 13 ;
R 2 is unsubstituted C 1-8 alkyl;
R 3 is hydrogen;
R 4 is hydrogen;
R 6 is hydrogen;
R 7 is hydrogen; and
R 8 is hydrogen.

4. The method of claim 1 , wherein the compound is selected from:

and enantiomers, diastereoisomers, tautomers, hydrates and solvates thereof;
and pharmaceutically acceptable salts of the foregoing.

5. A method of treating rheumatoid arthritis in a subject in need of such treatment, the method comprising administering to the subject a therapeutically effective amount of a compound having the following structure:

or a pharmaceutically acceptable salt thereof.

6. The method of claim 1 , 4 or 5 , wherein the subject is a human.
