inhibitors of guinea pig liver transglutaminase. The most effective inhibitors evaluated can be sorted into two subclasses: substituted cinnamoyl benzotriazolyl amides and the 3-(substituted cinnamoyl)pyridines, referred to more commonly as azachalcones. Kinetic evaluation of both of these subclasses revealed that they display reversible inhibition and are competitive with acyldonor TGase substrates at IC50

A series of cinnamic acid/4-aminoquinoline conjugates conceived to link, through a proper retro-enantio dipeptide, a heterocyclic core known to prevent hemozoin formation, to a trans-cinnamic acid motif capable of inhibiting enzyme catalytic Cys residues, were synthesized as potential dual-action antimalarials. The effect of amino acid configuration and the absence of the dipeptide spacer were also

ring systems with highly 3D character and are currently underrepresented in fragment screening libraries. A nuclear magnetic resonance (NMR) fragment screen identified 1,4-acylthiazepanes as new BET (bromodomain and extraterminal domain) bromodomain ligands; however, an efficient and readily diversified synthesis for library development has not been reported. Here we report a one-pot synthesis using
1,4-Thiazepanes 和 1,4-thiazepanones 代表具有高度 3D 特征的七元环系统,目前在片段筛选库中代表性不足。核磁共振 (NMR) 片段筛选将 1,4-酰基硫氮杂环鉴定为新的 BET(溴结构域和末端外结构域)溴结构域配体;然而,用于库开发的高效且易于多样化的合成尚未见报道。在这里,我们报告了使用 α,β-不饱和酯和 1,2-氨基硫醇形成 1,4-噻嗪酮作为具有高 3D 特征的 1,4-噻嗪酮的前体的一锅法合成。该反应在合理的时间(0.5-3 小时)内以良好的产率进行,并且可以耐受范围广泛的 α,β-不饱和酯。几个 1, 4-噻嗪类通过两步转化合成,并使用蛋白质观察 19F NMR 表征为新的 BET 溴结构域配体。这种合成应该可以方便地访问各种 3D 片段以筛选库。

biologically evaluation system well in highthroughput based on SPR technology, and identified a novel class of N, N-dibenzylcinnamamide (DBC) compounds as α-syn ligands through the assay. These compounds were proved to have high affinities against α-syn aggregates (KD < 10 nM), which well met the requirement of binding activity for the PET probe. These DBC compounds were firstly reported as α-syn ligands herein
