    Abstract:
    The CXCR2 SAR of a series of bicyclic antagonists such as the 2-aminothiazolo[4,5-d]pyrimidine 3b was investigated by systematic variation of the fused pyrimidine-based heterocyclic cores. Replacement of the aminothiazole ring with a 2-thiazolone alternative led to a series of thiazolo[4,5-d]pyrimidine-2(3H)-one antagonists with markedly improved biological and pharmacokinetic properties, which are suitable pharmacological tools to probe the in vivo effects of CXCR2 antagonism combined with the associated CCR2 activity.
