  摘要：

  摘要 根据先前的研究，制备了 66 种含有酰胺和 1,3,4-恶二唑部分的 2-苯基-4H-色酮衍生物作为潜在的端粒酶抑制剂。结果显示大多数标题化合物对端粒酶表现出显着的抑制活性。其中，一些化合物表现出最有效的端粒酶抑制活性（IC 50 < 1 µM），明显优于星形孢菌素（IC 50 = 6.41 µM）。此外，总结了清晰的构效关系，表明甲氧基的取代以及苯环上取代基的位置、类型和数量对端粒酶活性有显着影响。其中，化合物A33对端粒酶有显着的抑制作用。流式细胞仪分析表明，化合物A33可以将MGC-803细胞周期阻滞在G2/M期，并以浓度依赖性方式诱导细胞凋亡。同时，Western blotting 显示该化合物可以降低作为端粒酶片段的dyskerin 的表达。

  Optimization of a 1,3,4-oxadiazole series for inhibition of Ca2+/calmodulin-stimulated activity of adenylyl cyclases 1 and 8 for the treatment of chronic pain

  摘要：

  Adenylyl cyclases type 1 (AC1) and 8 (AC8) are group 1 transmembrane adenylyl cyclases (AC) that are stimulated by Ca2+/calmodulin. Studies have shown that mice depleted of AC1 have attenuated inflammatory pain response, while AC1 /AC8 double-knockout mice display both attenuated pain response and opioid dependence. Thus, AC1 has emerged as a promising new target for treating chronic pain and opioid abuse. We discovered that the 1,3,4-oxadiazole scaffold inhibits Ca2+/calmodulin-stimulated cyclic adenosine 3',5'-monophosphate (cAMP) production in cells stably expressing either AC1 or AC8. We then carried out structure-activity relationship studies, in which we designed and synthesized 65 analogs, to modulate potency and selectivity versus each AC isoform in cells. Furthermore, molecular docking of the analogs into an AC1 homology model suggests the molecules may bind at the ATP binding site. Finally, a prioritized analog was tested in a mouse model of inflammatory pain and exhibited modest analgesic properties. In summary, our data indicate the 1,3,4-oxadiazoles represent a novel scaffold for the cellular inhibition of Ca2+/calmodulin-stimulated AC1- and AC8 CAMP and warrant further exploration as potential lead compounds for the treatment of chronic inflammatory pain.

  66 2-phenyl-4H-chromone derivatives containing amide and 1,3,4-oxadiazole moieties were prepared as potential telomerase inhibitors. The results showed most of the title compounds exhibited significantly inhibitory activity on telomerase. Among them, some compounds demonstrated the most potent telomerase inhibitory activity (IC50 < 1 µM), which was significantly superior to the staurosporine (IC50
