attributed to its specific and selective inhibition of monoamine oxidase B (MAO-B). Further, HT-0411 was shown to improve 24 h memory in rodents in a contextual fear conditioning model. This report describes the lead optimization of a series of 5-(1-methyl-5-(trifluoromethyl)-1H-pyrazol-3-yl) thiophene-2-carboxamides that were identified as novel, potent, and selective inhibitors of MAO-B.

果蝇的初步工作小鼠证明,转录因子环状单磷酸腺苷(cAMP)响应元件结合蛋白(CREB)是记忆形成的主要控制基因。还发现CREB与记忆之间的关系在其他物种中也是如此,包括海狸鼠和大鼠。因此,众所周知的是,CREB激活在记忆增强中起着中心作用,并且CREB在记忆形成过程中被激活。基于这些发现,进行了利用CRE-萤光素酶(CRE-Luci)SK-N-MC细胞系的表型高通量筛选活动,以鉴定可通过次适量的福司高林增强CRE启动子转录激活的化合物。 。在筛选活动中发现了许多未知作用机制的小分子命中物,包括HT-0411。后续研究表明,HT-0411对CREB的激活归因于其对单胺氧化酶B(MAO-B)的特异性和选择性抑制。此外,在上下文恐惧条件模型中,HT-0411被证明可以改善啮齿动物的24 h记忆能力。本报告介绍了一系列5-(1-甲基-5-(三氟甲基)-1H-吡唑-3-基)噻吩-2-甲酰胺被确定为M
