  • Syntheses of [14C] and [2H4]PD0205520, an inhibitor of the tyrosine kinase activity of the epidermal growth factor receptor

    日期:2005.6
    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.

    The bromination by N-bromosuccinimide of various mesitylene derivatives, to produce arybnethyl bromides or bromoarylrnethyl bromides was compared in different reaction conditions. These compounds are intermediates in the synthesis of seylmethylisothiouronium labrnde salts, achieved by the quantitative addition of thiourea to the methyl bromide derivatives. The final products are potent inhibitors of
    在不同的反应条件下,比较了N-溴琥珀酰亚胺对各种均三甲苯衍生物的溴化反应,生成了亚芳基溴化溴或溴代芳基溴化乙基溴。这些化合物是通过将硫脲定量添加到甲基溴衍生物中而合成的甲基化异甲基脲盐化合物的中间体。最终产物是跨膜阳离子转运的有效抑制剂,因此对药理特性可能引起关注。证明了掺入对于用作亲和标记和化学计量研究很重要的放射性碳。

    the levo isomer of tetramisole. It is a broad spectrum anthelmintic which is used extensively as a veterinary drug for food producing animals. Metabolism and environmental studies necessitated the synthesis of 14C-labelled levamisole (6) and of its major metabolite (12). 14C-Tetramisole was obtained in two steps from 14C-thiourea. Resolution via salt formation and crystallization afforded 14C-levamisole

    Condensation of thiourea 1 with diethyl malonate 2 in the presence of sodium methoxide furnished 4,6-dihydroxy-2-mercaptopyrimidine 3. Compound 3 on methylation with diazomethane followed by oxidation with H5IO6/CrO3 in ethyl acetate gave 4,6-dimethoxy-2-methylsulphonylpyrimidine 5. Compound 5 on condensation with 2-mercapto-6-chlorobenzoic acid in the presence of a phase transfer catalyst, tetrabutylammonium bromide and sodium carbonate gave the title compound – pyrithiobac-sodium 6 with an overall yield of > 35% starting from thiourea. Following the above standardized procedure, using [14C]-thiourea in lieu of thiourea, 14C labelled product 6, was synthesized with an overall radiochemical yield > 30% (with respect to [14C]-thiourea) for further evaluations of environmental fate of 6, in soils and plants.
