制备方法与用途

用途

2-甲基-1,3-苯并恶唑-6-羧酸是苯并恶唑类化合物的一种。由于其良好的杀菌和生物活性，这种化合物在医药、农药、生物化学、染料及荧光增白等领域得到了广泛应用。

制备

在装有温度计、球形冷凝器和磁力恒温搅拌器的100mL三颈瓶中加入3-羧酸邻氨基苯酚。开启磁力搅拌，然后通过油浴加热至适当温度。缓慢滴加乙酸，并添加溴化四丁基铵（TBAB）。将混合物逐渐升温至100℃，并维持此温度反应4小时。反应结束后，趁热过滤去除杂质，收集滤液进行分馏，得到在177-179℃的浅黄色油状液体，即为2-甲基-1,3-苯并恶唑-6-羧酸。

  SB-334867 的二芳基脲类似物作为食欲素 1 受体拮抗剂

  摘要：

  作为我们开发 OX1-CB1 二价配体计划的一部分，我们需要更好地了解食欲素拮抗剂的基本构效关系 (SAR)。合成了一系列 SB-334867 类似物，并在钙动员测定中进行了评估。SAR 结果表明，2-甲基苯并恶唑部分可以被双取代的 4-氨基苯基取代而不会失去活性，并且缺电子系统通常在 1,5-萘啶部分用于 OX1 拮抗剂活性。特别是，较大的潜在接头如正己基的取代提供了化合物33与先导化合物 SB-334867 相比，对 OX1 受体具有同等活性。这些化合物在开发靶向orexin-1受体及其潜在异源二聚体的配体方面应该具有价值。
