  SAR studies of C2 ethers of 2H-pyrano[2,3-d]pyrimidine-2,4,7(1H,3H)-triones as nicotinic acid receptor (NAR) agonist

  摘要：

  Based on in house screening lead compound 1 for the NAR project, SAR studies have been focused on the modification of the C2 ethers of the pyrimidinedione core structure. In this effort, an unpredictable SAR trend was overcome in the alkyl ether and arylalkyl ether series to identify compound 24 with improved in vitro activity compared to nicotinic acid. More consistent and predictable SAR was achieved in the propargyl ether series. Lead compound 41 was identified with good in vitro and in vivo activity in rat, and much improved rat PK profile.

  cutaneous vasodilation “flushing” on the upper body and face. We discovered a pyranopyrimidinedione series to be nicotinic acid receptor agonists. A potent nicotinic acid receptor agonist from this series 5-(3-cyclopropylpropyl)-2-(difluoromethyl)-3H-pyrano[2,3-d]pyrimidine-4,7-dione}with reduced flushing side effect in dogs was identified.

  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。
