The design, synthesis and SAR studies of novel 4,5,6,7-tetrahydropyrazolopyrazines as metabotropic glutamate receptor 5 (mGluR5) negative allosteric modulators (NAMs) are presented in this letter. Starting from a HTS hit compound (1, IC50=477nM), optimization of various groups led to the synthesis of a potent mGluR5 NAM (32, IC50=75nM) with excellent rat PK profile and good brain penetration. This
这封信介绍了作为代谢型谷氨酸受体5(mGluR5)负变构调节剂(NAM)的新型4,5,6,7-四氢吡唑并吡嗪的设计,合成和SAR研究。从HTS命中化合物(1,IC50 = 477nM)开始,各种基团的优化导致合成了有效的mGluR5 NAM(32,IC50 = 75nM),具有出色的大鼠PK谱和良好的脑渗透性。该化合物在小鼠悬浮液模型(MED:30mg / kg)中产生了口服抗抑郁药样作用。

AbstractThis study aimed at describing a simple and facile synthesis of pyrazolyl/isoxazolyl 1,3,4-oxadiazole derivatives from the synthetic intermediates pyrazolyl/isoxazolyl carboxylates adopting conventional and ultrasound irradiation methods. In fact ultrasound-promoted synthesis led to the formation of title compounds in higher yields and in shorter reaction times when compared with conventional
摘要本研究旨在描述采用常规和超声辐照方法从合成中间体吡唑基/异恶唑基羧酸盐中简单,轻松地合成吡唑基/异恶唑基1,3,4-恶二唑衍生物的方法。实际上,与常规方法相比,超声促进的合成导致标题化合物的形成,产率更高,反应时间更短。所有化合物均通过IR,1 H NMR,13表征1 H NMR和质谱。评价合成的化合物的抗氧化和抗炎活性。生物测定结果表明,发现一些标题化合物比标准药物更有效。在所有测试的化合物中,呋喃基/吡啶基连接的吡唑基/异恶唑基甲氧基苯基磺酰基甲基恶二唑被鉴定为潜在的抗氧化剂和抗炎剂。 图形概要
