5-(4-Methyl-piperazin-1-yl)-pent-2-ynoic acid [4-(3-chloro-4-fluoro-phenylamino)-pyrido[3,4-d]pyrimidin-6-yl]-amide, PD0205520, was under investigation as a potential inhibitor of the tyrosine kinase (TK) activity of the epidermal growth factor receptor (EGFR) for cancer treatment. Both radio- and stable-isotope-labeled compounds were required for drug absorption, distribution, metabolism and excretion (ADME) and quantitative mass spectrometry bio-analytical studies. PD0205520 I4C-labeled in the pyrimidine ring system was prepared in seven steps in an overall radiochemical yield of 26% from [14C]thiourea. PD0205520 2H-Iabeled in the piperazine ring was synthesized in four steps in a 32% overall yield. Copyright © 2005 John Wiley & Sons, Ltd.
5-(4-甲基-哌嗪-1-基)-2-炔丁酸 [4-(3-氯-4-氟-苯基氨基)-吡啶[3,4-d]嘧啶-6-基]-酰胺,PD0205520,正在研究作为癌症治疗中表皮生长因子受体(EGFR)酪氨酸激酶(TK)活性的潜在抑制剂。药物吸收、分布、代谢和排泄(ADME)以及定量质谱生物分析研究需要放射性和稳定同位素标记的化合物。PD0205520在嘧啶环系统中的碳-14标记化合物通过七个步骤合成,整体放射化学产率为26%,原料为[14C]硫脲。PD0205520在哌嗪环中的氘标记化合物通过四个步骤合成,整体产率为32%。版权所有 © 2005 John Wiley & Sons, Ltd.
