  Synthesis and SAR Studies of 2-Oxoquinoline Derivatives as CB2 Receptor Inverse Agonists

  摘要：

  The highly CB2 selective cannabinoid receptor inverse agonist, 7-methoxy-2-oxo-8-pentyloxy-1,2-dihydroquinoline-3-carboxylic acid N-benzo[1,3]dioxol-5-ylmethyl)amide (JTE-907; 9b), served as the lead compound for investigating the structure-activity relationships of its analogues and in the search for more potent and effective CB2 receptor inverse agonists. A series of aromatic amides of 7-methoxy-2-oxo-8-pentyloxy-1,2-dihydroquinoline-3-carboxylic acid 6 was synthesized, and the CB2 receptor activities of the compounds were determined by a [S-35]GTP(gamma)S-binding assay using membranes of CHO cells stably transfected with the human CB2 receptor. As a result, all the compounds were defined as full CB2 receptor inverse agonists, and additionally, except for two 3,4-dihydroxyphenylalkylamides, they were found to be equally potent as SR144528.

  family of potential antitumor agents, and cannabinoid receptor 2 (CB2) is believed to be over-expressed in tumor cells. This study was designed to develop new radioligands for imaging of CB2 receptor in cancer using biomedical imaging technique positron emission tomography (PET). Carbon-11-labeled 2-oxoquinoline and 2-chloroquinoline derivatives, [11C]6a–d and [11C]9a–d, were prepared by O-[11C]methylation

  最近有人提出将大麻素作为潜在的抗肿瘤药物的新家族，并且认为大麻素受体2（CB2）在肿瘤细胞中过表达。这项研究旨在利用生物医学成像技术正电子发射断层扫描（PET）开发用于癌症中CB2受体成像的新型放射性配体。碳11标记的2-氧喹啉和2-氯喹啉衍生物[ 11 C] 6a - d和[ 11 C] 9a - d是通过使用[ 11 C] CH对相应的前体进行O- [ 11 C]甲基化制备的3OTf在基本条件下并通过简化的固相萃取（SPE）方法进行分离，以[ 11 C] CO 2为基础，以40％至50％的放射化学收率进行了分离，并将衰变校正为轰击结束（EOB）。EOB的总合成时间为15–20分钟，放射化学纯度> 99％，合成结束时的比活（EOS）为111–185 GBq /μmol。放射性配体结合试验表明，化合物6f，6b和9f表现出强大的体外结合亲和力，纳摩尔摩尔K i值，对CB2的选择性至少100-2000倍。
