  Synthesis and Biological Evaluation ofortho-ArylN-Hydroxycinnamides as Potent Histone Deacetylase (HDAC) 8 Isoform-Selective Inhibitors

  摘要：

  AbstractHistone deacetylases (HDACs) are a family of enzymes that play a crucial role in biological process and diseases. In contrast to other isozymes, HDAC8 is uniquely incapable of histone acetylation. In order to delineate its physiological function, we developed HDAC8‐selective inhibitors using knowledge‐based design combined with structural modeling techniques. Enzyme inhibitory analysis demonstrated that some of the resulting compounds (22 b, 22 d, 22 f, and 22 g) exhibited anti‐HDAC8 activity superior to PCI34051, a known HDAC8‐specific inhibitor, with IC50 values in the range of 5–50 nM. Among them, compound 22 d showed antiproliferative effects toward several human lung cancer cell lines (A549, H1299, and CL1‐5); it exhibited cytotoxicity against human lung CL1‐5 cells similar to that of SAHA yet without significant cytotoxicity for normal IMR‐90 cells. Expression profiling of HDAC isoforms in three cancer cell lines indicated that the HDAC8 level in CL1‐5 is higher than that in H1299 and CL1‐1 cells, a result consistent with the differential cytotoxicity of compound 22 d. These results suggest the effectiveness of our design concept, which may lead to a tool compound for studying the specific role of HDAC8 in cellular biological processes.

  香豆素和同异黄酮衍生物及类似物的合成：寻找新的抗真菌剂

  摘要：

  提交了一组 24 种具有香豆素和高异黄酮核心和结构类似物的合成衍生物，用于评估对各种念珠菌的抗真菌活性。肉汤微量稀释试验用于确定化合物的最低抑菌浓度 (MIC) 并验证可能的抗真菌作用机制。采用多种反应方法得到合成衍生物，得到六种新化合物。合成产物的结构通过FTIR光谱表征：1 H-NMR、13 C-NMR和HRMS。香豆素衍生物8表现出最好的抗真菌谱，表明香豆素环C-7位的戊氧基取代基可以增强生物活性。然后针对C.tropicis ATCC 13803 的生物膜对化合物8进行了评估，与生长对照组相比，在 0.268 µmol/mL 和 0.067 µmol/mL 的浓度下，生物膜的生物膜显着减少。为了更好地了解它们的抗真菌活性，化合物8和21对真菌细胞壁和质膜的作用方式进行了研究。据观察，两种化合物都没有直接与真菌质膜中的麦角甾醇或真菌细胞壁相互作用。这表明它们的生物活性是由于涉及其他药
