An electrochemical synthesis of 2-aminobenzoxazoles from 2-aminophenols and isothiocyanates was successfully developed in a one-pot fashion. Using inexpensive and widely available NaI and NaCl co-operatively in catalytic amounts, our electrosynthesis approach provided various 2-aminobenzoxazole products in moderate to high yields in an open-flask type undivided cell without using any external supporting
以一锅法成功开发了由 2-氨基苯酚和异硫氰酸酯电化学合成 2-氨基苯并恶唑。我们的电合成方法以催化量合作使用廉价且广泛可用的 NaI 和 NaCl,在不使用任何外部支持电解质和碱的情况下,在开放式烧瓶型未分隔电池中以中等至高产率提供各种 2-氨基苯并恶唑产品。该协议可用于以中等产率从相应的 2-苯硫酚合成 2-氨基苯并噻唑。该协议有很多好处。它不含金属且具有高度可扩展性,并在温和条件下使用廉价的介质和乙醇/水作为环保溶剂。
Synthesis and evaluation of benzoxazole derivatives as 5-lipoxygenase inhibitors
5-Lipoxygenase (5-LOX) is important enzyme in the biosynthesis of leukotrienes, and is a potential target in the treatment of asthma and allergy. We designed and synthesized a series of benzoxazoles and benzothiazoles as 5-LOX inhibitors. Fourteen compounds prepared showed the inhibition of LTC4 formation with IC50 value of 0.12-23.88 mu M. Also two compounds 2d and 2g showed improved airway hypersensitiveness. (C) 2010 Elsevier Ltd. All rights reserved.

Provided are a novel medicament for suppressing or preventing the metastasis of a malignant tumor such as carcinoma, a novel treatment or prevention method for suppressing or preventing the metastasis of a malignant tumor, etc. The medicament comprises a non-peptidic angiotensin type 2 receptor agonist as an active ingredient. In the medicament, the non-peptidic angiotensin type 2 receptor agonist may be, for example, a sulfonyl malonamide compound. The medicament may be a medicament for use in combination with an anticancer agent and/or an antitumor agent.
