AZD5122, N-(2-(2,3-difluorobenzylthio)-6-((2R,3R)-3,4-dihydroxybutan-2-ylamino)pyrimidin-4-yl)azetidine-1-sulfonamide was under investigation as a potential chemokine receptor CXCR2 antagonist for the treatment for inflammatory diseases. To gain a better understanding of the human pharmacokinetic profile, an exploratory phase I IV microtracer study was conducted using carbon-14 radiolabelled AZD5122. [14C]AZD5122 was carbon-14 labelled in the pyrimidine ring in five steps in an overall radiochemical yield of 19% from [14C]thiourea. The absolute oral bioavailability of AZD5122 was assessed in healthy subjects by an oral administration of AZD5122, followed by a concomitant intravenous [14C]AZD5122 microdose.
AZD5122,N-(2-(2,3-二氟苄硫基)-6-((2R,3R)-3,4-二羟基丁-2-基氨基)嘧啶-4-基)氮杂环丁烷-1-磺酰胺正在研究作为潜在的趋化因子受体 CXCR2 拮抗剂,用于治疗炎症性疾病。为了更好地了解人体药代动力学特征,使用碳 14 放射性标记的 AZD5122 进行了探索性 I IV 期微量示踪剂研究。 [14C]AZD5122 通过五个步骤在嘧啶环上进行碳 14 标记,[14C]硫脲的总放射化学产率为 19%。通过口服 AZD5122,然后同时静脉注射 [14C]AZD5122 微剂量,在健康受试者中评估 AZD5122 的绝对口服生物利用度。
