signaling in association with the N-methyl-d-aspartate receptor (NMDAR). We describe the synthesis of 1H-pyrazolo[3,4-b]pyridines and their utility as mGluR5 positive allosteric modulators (PAMs) without inherent agonist activity. A facile and convergent synthetic route provided access to a structurally diverse set of analogues that contain neither the aryl-acetylene-aryl nor aryl-methyleneoxy-aryl elements
代谢型谷氨酸受体5(mGluR5的)是用于治疗精神分裂症的有吸引力的靶点,因为它在与所述关联调节谷氨酸能信号传导作用Ñ甲基d天冬氨酸受体(NMDAR)。我们描述了1 H-吡唑并[3,4- b吡啶及其作为mGluR5阳性变构调节剂(PAM)的用途,无固有的激动剂活性。简便易行的合成路线提供了结构上多样化的类似物集合的途径,这些类似物既不包含芳基-乙炔基-芳基也不包含芳基-亚甲氧基-芳基元素,这是文献中描述的主要结构基序。结合研究表明,我们新化学型的成员在MPEP和CPPHA mGluR5变构位点不参与受体。SAR研究在第一个非MPEP位点PAM 1 H-吡唑并[3,4- b ]吡啶31(BMT-145027)达到高潮,以提高临床前啮齿动物学习和记忆模型的认知度。
