The present invention relates to novel cycloalkylalkane-carboxamides of the formula I
where the substituents have the following meanings:
A is C3-C6-cycloalkyl;
R1 is C1-C6-alkyl or C2-C6-alkenyl;
R2, R3 and R4 are hydrogen or, independently of this meaning, have one of the meanings of the radical R1;
n is 0 or 1;
Y is cyano or halogen;
w is phenyl, naphthyl or heteroaryl.
The present invention relates to compounds of formula (I) and the use of these compounds as pharmaceuticals, e.g. in preventing or treating a CXCR2 receptor mediated condition or disease.

A hit-to-lead optimisation programme was carried out on the Novartis archive screening hit, pyrimidine 2-((2,6-dichlorobenzyl)thio)-5-isocyano-6-phenylpyrimidin-4-ol 4, resulting in the discovery of CXCR2 receptor antagonist 24(2,3-difluorobenzyl)thio)-6-(2-(hydroxymethyl)cyclopropyl)-5-isocyanopyrimidin-4-ol 24. The SAR was investigated by systematic variation of the aromatic group at c-6, the linker between c-2 and the halogenated ring, and the c-5 nitrile moiety. (C) 2014 Elsevier Ltd. All rights reserved.
