  Structure-based optimization of oxadiazole-based GSK-3 inhibitors

  摘要：

  Inhibition of glycogen synthase kinase-3 (GSK-3) induces neuroprotective effects, e.g. decreases beta-amyloid production and reduces tau hyperphosphorylation, which are both associated with Alzheimer's disease (AD). The two isoforms of GSK-3 in mammalians are GSK-3 alpha and beta, which share 98% homology in their catalytic domains. We investigated GSK-3 inhibitors based on 2 different scaffolds in order to elucidate the demands of the ATP-binding pocket [1]. Particularly, the oxadiazole scaffold provided potent and selective GSK-3 inhibitors. For example, the most potent inhibitor of the present series, the acetamide 26d, is characterized by an IC50 of 2 nM for GSK-3 alpha and 17 nM for GSK-3 beta. In addition, the benzodioxane 8g showed up to 27-fold selectivity for GSK-3 alpha over GSK-3 beta, with an IC50 of 35 nM for GSK-3 alpha. Two GSK-3 inhibitors were further profiled for efficacy and toxicity in the wild-type (wt) zebrafish embryo assay to evaluate simultaneously permeability and safety. (C) 2012 Elsevier Masson SAS.

  2-Aryl-Δ-2-1,3,4-oxadiazoline-5-thione derivatives 2 were synthesized and their uv and ir spectra were studied. Correlation between σ-Hammett constants of aryl substituents and the differences in absorption maxima (Δv = v1-v2 in kK) of the electronic spectra of the deprotonated species were also evaluated. A new method for the synthesis of the 2-(amino)aryl derivatives 2v,w,x is also reported.

  owing to the emergence of SARS-CoV-2 mutants. This highlights the urgent need for the discovery of more effective drugs to combat COVID-19. As an important target for COVID-19 treatment, 3C-like protease (3CLpro) plays a crucial role in the replication of SARS-CoV-2. In our previous research, we demonstrated the potent inhibitory activities of compound A1, which contains a 2-sulfonyl-1,3,4-oxadiazole

  由严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 引起的冠状病毒病 (COVID -19) 大流行已成为重大公共卫生危机，对人类福祉构成重大威胁。尽管有疫苗，但由于 SARS-CoV-2 突变体的出现，COVID-19 仍在继续传播。这凸显了迫切需要发现更有效的药物来对抗 COVID-19。作为COVID-19治疗的重要靶点，3C样蛋白酶（3CL pro）在SARS-CoV-2的复制中发挥着至关重要的作用。在我们之前的研究中，我们证明了含有 2-磺酰基-1,3,4-恶二唑支架的化合物A1对 SARS-CoV-2 3CL pro具有有效的抑制活性。在此，我们对A1的结构优化进行了详细研究，并对构效关系进行了研究。在所测试的各种化合物中，亚砜D6 对 SARS-CoV-2 3CL pro表现出有效的不可逆抑制活性 (IC 50 = 0.030 μM) ，并对宿主半胱氨酸蛋白酶（如组织蛋白酶
