resulting oximelibrary was screened accordingly toward the GABAtransporter subtype 1 (GAT1), a drug target for several neurological disorders. After assessing sublibraries’ activities for inhibition of reporter ligand binding, hits in active ones were directly identified. This could be achieved by recording mass transitions for the reporter ligand as well as those predicted for the library components
这项研究提出了一种有效的筛选方法,该方法基于基于质谱(MS)的结合测定(MS Binding Assays)和亲和力选择质谱(ASMS)的组合,这些筛查被定制用于筛选具有相同质谱碎片模式的结构均质文库。在具有羟胺官能团的乳酸衍生物与醛反应后,针对几种神经系统疾病的药物靶点GABA转运蛋白亚型1(GAT1)相应地筛选所得的肟库。在评估子图书馆抑制报告配体结合的活性后,直接鉴定出活性物质的命中。这可以通过在多反应监测模式下使用三重四极杆质谱仪运行的单个LC-MS / MS中记录报告配体的质量跃迁以及库组分的预测跃迁来实现。可以通过计算IC可靠地确定具有预定义亲和力的匹配来自文库成分和报道分子配体的特定结合浓度的50值。该策略的应用揭示了六个命中,其中两个命中被重新合成以进行进一步的生物学评估。因此,最好的一个在MS结合分析中显示出ap K i为7.38,在[ 3 H] GABA吸收分析中显示出pIC

derivatives, are chemically inert due to their intrinsic aromaticity and low polarity. The catalytic asymmetric dearomatization (CADA, coined by You and co-workers) of the nonactivated arenes represents a formidable challenge. We herein demonstrated an organocatalytic asymmetric dearomatizing hetero-Diels–Alderreaction of benzene derivatives. The tunable regioselectivity of this strategy allowed delivery of
非活化芳烃,如苯衍生物,由于其固有的芳香性和低极性,在化学上是惰性的。非活化芳烃的催化不对称脱芳构化(CADA,由 You 及其同事创造)是一项艰巨的挑战。我们在此证明了苯衍生物的有机催化不对称脱芳构化杂-Diels-Alder 反应。该策略的可调区域选择性允许以优异的立体选择性递送多种立体化学复杂的多环化合物和氧杂环己烷。产品的高度复杂性和三维度对其在材料科学和药物发现中的潜在应用至关重要。机理研究表明,该反应通过手性四取代亚乙烯基进行邻苯醌甲基化物 (VQM) 中间体,它非常有效地克服苯衍生物的芳香性损失以及伴随的手性转移。

Kinetic stabilization of the native state of transthyretin is an effective mechanism for preventing protein misfolding. Because transthyretin misfolding plays an important role in transthyretin amyloid diseases, inhibiting such misfolding can be used as an effective treatment or prophylaxis for such diseases. Treatment methods are disclosed.
