  Evaluation of Quinazoline Analogues as Glucocerebrosidase Inhibitors with Chaperone Activity

  摘要：

  Gaucher disease is a lysosomal storage disorder (LSD) caused by deficiency in the enzyme glucocerebrosidase (GC). Small molecule chaperones of protein folding and translocation have been proposed as a promising therapeutic approach to this LSD. Most small molecule chaperones described in the literature contain an iminosugar scaffold. Here we present the discovery and evaluation of a new series of GC inhibitors with a quinazoline core. We demonstrate that this series can improve the translocation of GC to the lysosome in patient-derived cells. To optimize this chemical series, systematic synthetic modifications were performed and the SAR was evaluated and compared using three different readouts of compound activity: enzymatic inhibition, enzyme thermostabilization, and lysosomal translocation of GC.

  A mild and highly efficient catalytic amination procedure for chloroheteroarenes at ambient temperature using the Pd/PTABS catalytic system is reported. The protocol is selective for the amination of chloroheteroarenes using secondary amines such as piperidine, pyrrolidine, and several others. The exceptional mildness of the developed protocol is beneficial for the synthesis of a crucial Buparlisib

  据报道，在室温下使用Pd / PTABS催化体系进行的氯杂芳烃温和高效的催化胺化程序。该方案对于使用仲胺（例如哌啶，吡咯烷和其他几种胺）进行氯杂芳烃的胺化反应具有选择性。所开发方案的非凡温和性，对于关键的布氏替尼中间体的合成以及以竞争性收率进行阿格列汀的正式合成都是有益的。
