  10-Substituted 11-Oxygenated (R)-Aporphines:  Synthesis, Pharmacology, and Modeling of 5-HT_1A Receptor Interactions

  摘要：

  Derivatives of the selective serotonin 5-HT1A receptor agonist (R)-11-hydroxy-10-methylaporphine (2) having various substituents in the C10-position or at the nitrogen have been synthesized from natural morphine or 6-O-acetylcodeine, respectively. The C10-substituents were introduced using efficient Stille or Suzuki cross-coupling reactions. The compounds were evaluated for their affinities to 5-HT1A and dopamine (DA) D-1 and D-2A receptors in vitro. All compounds tested displayed low (micromolar) affinities to D-1 and D-2A receptors. In addition, changes in steric bulk and/or electronic properties of the C10-substituent as compared to a C10-methyl group, as well as substitution of the N-methyl group for a hydrogen or a larger N-alkyl group, produced a marked decrease in the affinities to 5-HT1A receptors. Selected compounds that displayed moderate to high affinities to 5-HT1A receptors were evaluated for their ability to stimulate 5-HT1A receptors in vivo. The evaluated compounds behaved as agonists at 5-HT1A receptors, except for the N-propyl analogue of 2, (R)-11-hydroxy-10-methyl-N-propylnoraporphine (23), which displayed weak DA receptor agonism at the doses tested. Hence, the substitution pattern of 2 (a C10-methyl, a C11-hydroxy, and an N-methyl group) appears to be optimal for potent interaction of 10,11-disubstituted (R)-aporphines with 5-HT1A receptors. Modeling of ligand-5-HT1A receptor interactions was performed in an attempt to rationalize the observed affinity data. The binding site model suggests the presence of a ''methyl pocket'' in the 5-HT1A receptor binding site. The C11-methoxy-substituted aporphines appear to have a different binding mode compared to 2, implying a different accessibility of these compounds to the ''methyl pocket''.

  (R)-(−)-2-[11C]Methoxy-N-n-propylnorapomorphine ([11C]MNPA ([11C]2)) is an agonist radioligand of interest for imaging D2/D3 receptors in vivo. Here we sought to develop an improved radiosynthesis of this radioligand. Reference 2 was synthesized in nine steps with an overall yield of about 5%, starting from codeine. Trimethylsilyldiazomethane proved to be a practical improvement in comparison to diazomethane in the penultimate methylation step. A protected precursor for radiolabeling ((R)-(−)-2-hydroxy-10,11-acetonide-N-n-propylnoraporphine, 4) was prepared from (R)-(−)-2-hydroxy-N-n-propylnorapomorphine (1) in 30% yield. [11C]2 was prepared from 4 via a two-step one-pot radiosynthesis. The first step, methylation of 4 with [11C]methyl triflate, occurred in quantitative radiochemical yield. The second step, deprotection of the catechol moiety with HCl and heat, yielded 60–90% of [11C]2 giving an overall incorporation yield from [11C]methyl triflate of 60–90%. In a typical run more than 1 GBq of [11C]2, was produced from carbon-11 generated from a 10-min proton irradiation (16 MeV; 35 µA) of nitrogen–hydrogen target gas. The radiochemical purity of [11C]2 was > 99% and specific radioactivity at the time of injection was 901±342 GBq/µmol (n=10). The total synthesis time was 35–38 min from the end of radionuclide production. The identity of [11C]2 was confirmed by comparing its LC-MS/MS spectrum with those of reference 2 and (R)-(−)-10-methoxy-2,11-dihydroxy-N-n-propylnoraporphine.

  (R)-(-)-2-[11C]甲氧基-N-正丙基去甲吗啡（[11C]MNPA ( [11C]2)）是一种激动剂放射性配体，可用于体内 D2/D3 受体成像。在此，我们试图开发一种改进的放射性配体的放射合成方法。参考 2 由可待因开始，分九步合成，总产率约为 5%。在倒数第二个甲基化步骤中，与重氮甲烷相比，三甲基硅基重氮甲烷被证明是一种切实可行的改进。用于放射性标记的受保护前体（(R)-(-)-2-羟基-10,11-丙酮-N-正丙基去甲吗啡，4）是由(R)-(-)-2-羟基-N-正丙基去甲吗啡（1）制备的，收率为 30%。[11C]2是通过两步一步放射合成法从4制备的。第一步，用[11C]甲基三酸酯对 4 进行甲基化，放射性化学收率为定量。第二步，用盐酸和加热对儿茶酚分子进行脱保护，可获得 60-90% 的 [11C]2 ，因此[11C]三氯甲烷的总掺入率为 60-90%。在一次典型的运行中，通过对氮氢靶气进行 10 分钟质子辐照（16 MeV; 35 µA）产生的碳-11，生成了超过 1 GBq 的[11C]2。[11C]2的放射化学纯度大于99%，注入时的比放射性为901±342 GBq/µmol（n=10）。从放射性核素生产结束算起，总合成时间为 35-38 分钟。通过比较[11C]2 与参考 2 和(R)-(-)-10-甲氧基-2,11-二羟基-N-正丙基去甲吗啡的 LC-MS/MS 图谱，确认了[11C]2 的身份。Copyright © 2009 John Wiley & Sons, Ltd.
