A series of 3,4- and 3,5-disubstituted phenyl-containing cyclobutenedione analogues were synthesized and evaluated as CXCR2 receptor antagonists. Variations in the disubstitution pattern of the phenyl ring afforded new compounds with potent CXCR2 binding affinity in the low nanomolar ranges. Moreover, two potent compounds 19 and 26 exhibited good oral pharmacokinetic profiles.
合成了一系列的3,4-和3,5-二取代的含苯基环丁烯二酮类似物,并将其评估为CXCR2受体拮抗剂。苯环解离模式的变化提供了在低纳摩尔范围内具有有效CXCR2结合亲和力的新化合物。此外,两种有效的化合物19和26表现出良好的口服药代动力学特征。
