  摘要：

  数十年来，烟酸已在临床上用于控制血清脂蛋白。烟酸降低极低密度脂蛋白（VLDL）-胆固醇、低密度脂蛋白（LDL）-胆固醇和脂蛋白-a（LPa），对升高高密度脂蛋白（HDL）-胆固醇也有效。然而，烟酸在临床使用中具有多种副作用。最显着的是上半身和面部强烈的皮肤血管舒张“潮红”。我们发现吡喃并嘧啶二酮系列是烟酸受体激动剂。该系列中一种有效的烟酸受体激动剂 {5-(3-cyclopropylpropyl)-2-(difluoromethyl)-3 H- pyrano[2,3 - d ]pyrimidine-4,7-dione}，可减少狗的潮红副作用被识别。

• Discovery of triazolopyrimidine-based PDE8B inhibitors: Exceptionally ligand-efficient and lipophilic ligand-efficient compounds for the treatment of diabetes

  PDE8B is a cAMP-specific isoform of the broader class of phosphodiesterases (PDEs). As no selective PDE8B inhibitors had been reported, a high throughput screen was run with the goal of identifying selective tools for exploring the potential therapeutic utility of PDE8B inhibition. Of the numerous hits, one was particularly attractive since it was amenable to rapid deconstruction leading to inhibitors with very high ligand efficiency (LE) and lipophilic ligand efficiency (LLE). These triazolopyrimidines were optimized for potency, selectivity and ADME properties ultimately leading to compound 42. This compound was highly potent and selective with good bioavailability and advanced into pre-clinical development. (C) 2012 Elsevier Ltd. All rights reserved.
