  Chemical Modification of the Multitarget Neuroprotective Compound Fisetin

  摘要：

  Many factors are implicated in age-related central nervous system (CNS) disorders, making it unlikely that modulating only a single factor will provide effective treatment. Perhaps a better approach is to identify small molecules that have multiple biological activities relevant to the maintenance of brain function. Recently, we identified an orally active, neuroprotective, and cognition-enhancing molecule, the flavonoid fisetin, that is effective in several animal models of CNS disorders. Fisetin has direct antioxidant activity and can also increase the intracellular levels of glutathione (GSH), the major endogenous antioxidant. In addition, fisetin has both neurotrophic and anti-inflammatory activity. However, its relatively high EC50 in cell based assays, low lipophilicity, high topological polar surface area (tPSA), and poor bioavailability suggest that there is room for medicinal chemical improvement. Here we describe a multitiered approach to screening that has allowed us to identify fisetin derivatives with significantly enhanced activity in an in vitro neuroprotection model while at the same time maintaining other key activities.

  4-(二乙氨基)苯甲醛支架的扩展探索对前列腺癌醛脱氢酶活性和抗增殖活性的影响

  摘要：

  醛脱氢酶 (ALDH) 在包括前列腺癌在内的各种肿瘤类型中过度表达，被认为是治疗干预的潜在靶点。4-(二乙氨基)苯甲醛 (DEAB) 已被广泛报道为 ALDH 同种型的泛抑制剂，在这里，我们报告了 40 种 DEAB 类似物在前列腺癌细胞中的合成、ALDH 同种型选择性和细胞效力；三种类似物（14、15和16 ）显示出对 ALDH1A3 的有效抑制活性，两种类似物（18和19）显示出对 ALDH3A1 的有效抑制活性。值得注意的是，16 种类似物显示出增加的细胞毒性（IC 50= 10–200 μM) 与 DEAB (>200 μM) 相比对三种不同的前列腺癌细胞系。类似物14和18对患者来源的原发性前列腺肿瘤上皮细胞比 DEAB 更有效，作为单一药物或与多西紫杉醇联合治疗。总之，我们的研究支持使用 DEAB 作为 ALDH 抑制剂，但也揭示了密切相关的类似物，具有更高的选择性和效力。

  The present invention relates to the dyeing of keratin materials using two colorless dye precursors, at least one of which contains a disulfide/thiol unit, said precursors reacting together chemically to form the color in situ. The process according to the invention makes it possible in the context of certain variants to solve the problems caused by the color generated during the process, while at the same time not degrading the efficacy of the coloration, and especially of the lightening effect. The colorations obtained are moreover powerful, chromatic, sparingly selective, and fast with respect to external agents such as sunlight, perspiration and especially shampoo.

  本发明涉及使用两种无色染料前体对角蛋白材料进行染色，其中至少一种含有二硫化物/巯基单元，这些前体在化学上相互反应以在原位形成颜色。根据本发明的方法使得在某些变体情况下能够解决染色过程中产生的问题，同时不降低染色的功效，特别是减淡效果。所获得的染色品不仅强大、色彩鲜艳、选择性较少，而且对于阳光、汗水和尤其是洗发水等外部因素具有快速的耐久性。
