Design, synthesis and Structure–activity relationship studies of new thiazole-based free fatty acid receptor 1 agonists for the treatment of type 2 diabetes
The free fatty acid receptor 1 (FFA1/GPR40) has attracted interest as a novel target for the treatment of type 2 diabetes. Several series of FFA1 agonists including TAK-875, the most advanced compound terminated in phase III studies due to concerns about liver toxicity, have been hampered by relatively high molecular weight and lipophilicity. Aiming to develop potent FFA1 agonists with low risk of
Palladium-Catalyzed Benzylation of Heterocyclic Aromatic Compounds
作者:David Lapointe、Keith Fagnou
DOI:10.1021/ol901689q
日期:2009.9.17
Broadly applicable palladium-catalyzed heteroarene benzylation reactions are described with a focus on the most challenging heterocyclic classes under traditional benzylation techniques such as sulfur-containing heterocycles and those bearing functional groups that would be incompatible with reactions requiring Lewis acids and/or strong bases.

Through the introduction of an aryl chloride substituent, the selectivity of palladium-catalyzeddirectarylation may be diverted to provide alternative regioisomeric products in high yields. In cases where low reactivity is typically observed, the presence of the carbon−chlorine bond can serve to enhance reactivity and provide superior outcomes. From a strategic perspective, the C−Cl bond is easily

both histamine-stimulated and dcAMP-stimulated uptake of amino[14C]pyrine. These compounds inhibited the H+K+-sensitive ATPase enzyme in isolated gastric microsomes. A direct correlation existed between inhibition of 14C uptake, in vivo antisecretory activity, and inhibition of the H+K+-ATPase enzyme. The more potent antisecretory compounds 18, 32, and 47 were also the more potent enzyme inhibitors
制备了一系列结构Ⅱ和Ⅲ的杂环(芳氧基)烷基胺,发现它们具有胃的抗分泌活性。在制备的各种取代的噻唑,苯并恶唑和苯并噻唑中,噻唑18,苯并恶唑32和苯并噻唑47在幽门结扎的大鼠模型中表现出与雷尼替丁体内相当的胃抗分泌能力。在分离的兔壁系统中,一系列噻唑,苯并恶唑和苯并噻唑在抑制组胺刺激和dcAMP刺激的氨基[14C]嘌呤摄取方面也表现出与雷尼替丁相似的效价。这些化合物抑制了分离的胃微粒体中的H + K +敏感ATPase。抑制14C摄取与体内抗分泌活性之间存在直接关系,和抑制H + K + -ATPase。更有效的抗分泌化合物18、32和47也是更有效的酶抑制剂。这些数据表明,在这些系列化合物中,负责观察到的体外和体内胃抗分泌活性的机制是抑制H + K +-敏感性ATPase的结果。
