β-Secretase (BACE1, β-site APP cleaving enzyme) is one of the most challenging therapeutic targets in the field of Alzheimers disease (AD) research. This enzyme catalyses the formation of neuronal amyloid β (Aβ) plaques, whose increased production is a key event in the initial pathogenesis of AD. As a consequence, many BACE1 inhibitors have been developed by several research groups. In the present work, after an analysis of tetraline derivatives reported in a Takeda patent, we designed and synthesized some analogues, making appropriate structural modifications, in order to try to improve the bioavailability features and the activities of Takeda compounds. All the new derivatives were tested on BACE1 with the TR-FRET (Time Resolved-Fluorescence Resonance Energy Transfer) technology and one of them showed a promising inhibitory activity value.
β分泌酶(BACE1,β位点APP裂解酶)是阿尔茨海默病(AD)研究领域最具挑战性的治疗靶点之一。这种酶催化神经元淀粉样β(Aβ)斑块的形成,而淀粉样β斑块的生成增加是阿尔茨海默病最初发病机制中的一个关键事件。因此,一些研究小组开发了许多 BACE1 抑制剂。在本研究中,我们在分析了武田专利中报道的四氢萘衍生物后,设计并合成了一些类似物,并对其结构进行了适当的修改,以尝试改善武田化合物的生物利用特性和活性。所有新衍生物都通过 TR-FRET(时间分辨荧光共振能量转移)技术对 BACE1 进行了测试,其中一种衍生物显示出了良好的抑制活性值。
