paper, the discovery of 11H-dibenz[b,e]azepines (morphanthridines) and dibenz[b,f][1,4]oxazepines is described as extremely potent agonists of the TRPA1 receptor. This has led to the discovery that most of the known tear gases are potent TRPA1 activators. The synthesis and biological activity of a number of substituted morphanthridines and dibenz[b,f][1,4]oxazepines have given insight into the SAR around
TRPA1通道可以被认为是刺激性化学物质的关键生物传感器。在本文中,发现11 H- dibenz [ b,e ]氮杂卓(吗啡啶)和dibenz [ b,f ] [1,4]恶氮杂卓的发现被描述为TRPA1受体的强效激动剂。这导致发现大多数已知的催泪瓦斯都是有效的TRPA1活化剂。许多取代的吗啡啶和二苯并[ b,f ] [1,4]奥氮平的合成和生物学活性已经使此类TRPA1激动剂周围的SAR有了更深入的了解,EC 50值范围从1μM到0.1 nM。化合物6和32可以认为它是迄今为止已知的最有效的TRPA1激动剂,目前已成功使用6种激动剂作为TRPA1拮抗剂发现中的筛选工具。配体(例如6和32)作为药理学工具的使用可能有助于TRPA1通道的基础知识,并促进TRPA1拮抗剂的开发,以作为涉及TRPA1活化的疾病(包括哮喘和疼痛)的潜在治疗方法。
