  摘要：

  查耳酮（1,3-二苯基丙-2-烯-1-酮）和许多其他α,β-不饱和羰基化合物的亲电性质对其生物活性至关重要，而生物活性通常是基于硫醇介导的调节过程。为了更好地预测它们的生物活性，我们开发了一种简单的筛选方法，用于评估噻-迈克尔加成反应的二阶速率常数（k2）。因此，在添加半胱胺后，16 种不同装饰的羟基烷氧基查耳酮的结构-活性关系得以明确。此外，在其他天然存在的 α、β-不饱和羰基化合物中，姜黄素和肉桂醛的 k2 值得到了提高，而肉桂酸或酯类则没有反应或反应非常缓慢。

  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。

  Resveratrol and closely related stilbenoids belong to the most intensively studied biologically active compounds. This interest evoked several attempts to prepare such compounds in a convenient synthetic way. Our approach allowed obtaining largely methoxystilbenes, formed asE-isomers only (using Wittig–Horner synthesis as the key step), which were further demethylated by boron tribromide. The hydroxymethoxystilbenes (e.g. pterostilbene) were prepared using isopropyl protection, later selectively deprotected by boron trichloride. The method is suitable for preparing such compounds in a large amount. Effects of the obtained stilbene derivatives on immunobiological responses triggered by lipopolysacharide and interferon-γ were tested under in vitro conditions. Namely production of nitric oxide (NO) was investigated, and relation between the molecular structure and immunobiological activity was assessed.

  白藜芦醇及其密切相关的蒽醌类化合物属于研究最为深入的生物活性化合物之一。这种兴趣引发了几次尝试以便利的合成方式制备这类化合物。我们的方法允许获得大量的甲氧基蒽醌类化合物，仅形成E-异构体（使用Wittig-Horner合成作为关键步骤），随后通过三溴化硼进行去甲基化。羟甲氧基蒽醌类化合物（例如蓝莓素）采用异丙基保护制备，后来通过三氯化硼进行选择性去保护。该方法适用于大量制备这类化合物。在体外条件下测试了所获得的蒽醌衍生物对脂多糖和干扰素-γ引发的免疫生物学反应的影响。具体而言，研究了一氧化氮（NO）的产生，并评估了分子结构与免疫生物学活性之间的关系。

  N,N′-((4-(Dimethylamino)phenyl)methylene)bis(2-phenylacetamide) was discovered by using 3D pharmacophore database searches and was biologically confirmed as a new class of CB2 inverse agonists. Subsequently, 52 derivatives were designed and synthesized through lead chemistry optimization by modifying the rings A–C and the core structure in further SAR studies. Five compounds were developed and also

  N , N '-((4-(二甲氨基)苯基)亚甲基)双(2-苯基乙酰胺)是通过使用3D药效团数据库搜索发现的，并被生物学证实为一类新的CB 2反向激动剂。随后，在进一步的 SAR 研究中，通过修饰环 A-C 和核心结构，通过先导化学优化设计和合成了 52 种衍生物。开发了五种化合物并证实它们是 CB 2反向激动剂，具有最高的 CB 2结合亲和力（CB 2 K i为 22–85 nM，EC 50为 4–28 nM）和最佳选择性（CB 1 /CB 2235 到 909 倍）。此外，破骨细胞生成生物测定表明 PAM 化合物对破骨细胞形成有很大的抑制作用。特别是，化合物26即使在0.1 μM的低浓度下也表现出72%的抑制活性。细胞毒性试验表明，PAM 化合物对破骨细胞生成的抑制作用不是由其细胞毒性引起的。因此，这些 PAM 衍生物可作为开发新型抗骨质疏松药物的潜在先导物。
