[EN] CYCLIC AMIDE DERIVATIVES AS INHIBITORS OF 11 - BETA - HYDROXYSTEROID DEHYDROGENASE AND USES THEREOF [FR] DÉRIVÉS D'AMIDE CYCLIQUES À UTILISER EN TANT QU'INHIBITEURS DE 11-BÊTA-HYDROXYSTÉROÏDE DÉSHYDROGÉNASE ET UTILISATIONS DE CEUX-CI
Fischer-type indolization of N-aryl-C-cyclopropyl hydrazones generated in situ followed by chemoselective reduction using tert-butyl iodide as an anhydrous HI generator was developed. This protocol provides indoles bearing carboxylic acid derivative units. A series of control experiments indicated the HI-mediated formation and reduction of spirocyclopropyl indolenines. Anhydrous HI functions as a Brønsted
开发了原位产生的N-芳基-C-环丙基腙的 Fischer 型吲哚化,然后使用叔丁基碘作为无水 HI 发生器进行化学选择性还原。该协议提供了带有羧酸衍生物单元的吲哚。一系列对照实验表明 HI 介导的螺环丙基二氢吲哚的形成和还原。无水 HI 可作为布朗斯台德酸和还原剂,促进不稳定反应中间体和碘化混合物在平衡状态下的成功转化。
Discovery and Optimization of Tetrahydroisoquinoline Derivatives To Enhance Lysosome Biogenesis as Preclinical Candidates for the Treatment of Alzheimer’s Disease
More than 55 million individuals are suffering from Alzheimer’s disease (AD), while the effective therapeutic strategies remain elusive. Our previous study identified a lysosome-enhancing lead compound LH2–051 with a tetrahydroisoquinoline scaffold through a novel dopamine transporter-cyclin-dependent kinase 9-transcription factor EB (DAT-CDK9-TFEB) regulation mechanism to promote TFEB activation and
