  Short and efficient syntheses of analogues of way-100635: new and potent 5-HT1A receptor antagonists

  摘要：

  Simple syntheses of four new and potent analogues of the 5-HT1A receptor ligand, WAY-100635 are described, namely the 6-(pyridinyl)-bromo-, the 6-(pyridinyl)-fluoro-, the pyrimidine- and the 5-(pyridinyl)-bromo-analogues. The first three analogues were obtained by aromatic nucleophilic substitution of the 2,6-dihalogenopyridine (activated or not as an N-oxide) or of the 2-chloropyrimidine with the corresponding amine nucleophile as a key step. The fourth analogue, the 5-(pyridinyl)-bromo-analogue, was synthesized from the 2-amino-5-bromopyridine via a progressive elongation of the skeleton. The four compounds described are all full antagonists and show good in vitro binding affinities (K-i). (C) 2001 Elsevier Science Ltd. All rights reserved.

  6b-d). Comparative radiolabelling of these precursors with fluorine-18 (positron-emitting isotope, 109.8 min half-life) clearly demonstrated that only ortho-fluorination in this pyridine series, and not meta-fluorination, is of interest for the preparation of a radioligand by nucleophilic heteroaromatic substitution. 6-[(18)F]Fluoro-WAY-100635 ([(18)F]5a) can be efficiently synthesized in one step, either

  近年来，人们在设计，合成和药理表征5-HT（1A）受体拮抗剂WAY-100635的放射性氟化衍生物上进行了大量工作，以利用PET在人脑中体内研究这些受体。合成了WAY-100635的（吡啶基-6）-氟和（吡啶基-5）-氟类似物（6-氟和5-氟WAY-100635，5a / 6a）以及相应的氯，溴-和硝基衍生物作为标记的前体（5b-d和6b-d）。这些前体与氟18的比较放射性标记（发射正电子的同位素，半衰期为109.8分钟）清楚地表明，只有这种吡啶系列中的邻位氟化而不是间位氟化对通过亲核试剂制备放射性配体感兴趣杂芳族取代。6-[（（18F）] Fluoro-WAY-100635（[（18F）] 5a）可以一步有效地从相应的6-溴前体中合成（使用常规方法在145摄氏度下加热10分钟）或来自相应的6-硝基前体（使用100 W微波活化1分钟）。通常，使用15-25 mCi（0.55-0.92 GBq）的6-[（（18）F]
