The inhibition of aldosterone synthase (CYP11B2) may be an effective treatment of hypertension and heart failure, among other ailments. Previously reported benzimidazole CYP11B2 inhibitors led the way for bioisosteric imidazopyridines that are both potent and selective over CYP11B1.
herein a supramolecular catalyst harnessing Zn⋅⋅⋅N interactions that binds to pyridine-like substrates as tight as it can be found in some enzymes. The distance and spatial geometry between the active site and the substrate binding site is ideal to target unprecedented meta-selective iridium-catalyzed C−Hbondborylations with enzymatic Michaelis–Menten kinetics, besides unique substrate selectivity and

hyperphosphorylation of tau protein in the Alzheimer’s disease (AD) pathology. A series of novel thieno[3,2-c]pyrazol-3-amine derivatives were designed and synthesised and evaluated as potential GSK-3β inhibitors by structure-guided drug rational design approach. The thieno[3,2-c]pyrazol-3-amine derivative 16b was identified as a potent GSK-3β inhibitor with an IC50 of 3.1 nM in vitro and showed accepted
摘要 糖原合酶激酶 3β (GSK-3β) 在阿尔茨海默病 (AD) 病理学中催化 tau 蛋白的过度磷酸化。设计并合成了一系列新型噻吩并[3,2 - c ]吡唑-3-胺衍生物,并通过结构指导的药物合理设计方法评估其作为潜在的GSK-3β抑制剂。噻吩并[3,2 - c ]吡唑-3-胺衍生物16b被鉴定为有效的GSK-3β抑制剂,体外IC 50为3.1 nM ,并显示出可接受的激酶选择性。在细胞水平上,16b在高达 50 μM 的浓度下对 SH-SY5Y 细胞的活力没有显示毒性,并且靶向 GSK-3β,在 Ser9 处磷酸化 GSK-3β 增加。蛋白质印迹分析表明,16b以剂量依赖性方式降低了 Ser396 位点的磷酸化 tau。此外,16b有效增加 β-catenin 以及 GAP43、N-myc 和 MAP-2 的表达,并促进分化的神经元神经突生长。因此,噻吩并[3,2 - c ]吡唑-
