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.
