  摘要：

  业已表明，抑制氯离子流入并因此降低脑灰质星形细胞中主要细胞类型的细胞内氯水平的试剂在体外和体内均抑制星形胶质细胞的肿胀。在我们的实验室中，已经合成了4-[（（N-烷基-1,3-二氧杂-1H，3H-异吲哚基-5-基）氧基]链烷酸和相关衍生物，并测试了降低细胞内星形细胞氯化物水平的能力。建立了体外培养的大鼠星形胶质细胞模型。通常，具有氮取代基（例如相对小的烷基）的衍生物在0.1 mM和/或0.5 mM的水平上具有活性，而较大的取代基（例如环戊基和环己基）的活性较低。芳环上的卤素取代没有增强活性。

  Discovery of a Potent Small Molecule IL-2 Inhibitor through Fragment Assembly

  摘要：

  Using a site-directed fragment discovery method called tethering, we have identified a 60 nM small molecule antagonist of a cytokine/receptor interaction (IL-2/IL2Ralpha) with cell-based activity. Starting with a low micromolar hit, we employed a combination of tethering, structural biology, and computational analysis to design a focused set of 20 compounds. Eight of these compounds were at least 5-fold more active than the original hit. One of these compounds showed a 50-fold enhancement and represents the highest affinity inhibitor reported against this protein-protein target class. This method of coupling selected fragments with a low micromolar hit shows great potential for generating high-affinity lead compounds.

  A series of [(3-aryl-1,2-benzisoxazol-6-yl)oxy]acetic acids was synthesized and tested for diuretic activity in saline-loaded mice and in conscious, water-loaded dogs. The structural requirements for good diuretic activity in both mice and dogs were found to be very specific. In summary, the compounds with the best diuretic activity (13i, 13q, and 13ff) were substituted with a 2-fluorophenyl group

  合成了一系列的[（3-芳基-1,2-苯并恶唑-6-基）氧基]乙酸，并测试了在有盐负荷的小鼠和有意识的有水负荷的狗中的利尿活性。发现在小鼠和狗中良好的利尿活性的结构要求非常具体。总之，具有最佳利尿活性的化合物（13i，13q和13ff）在3位被2-氟苯基取代，在7位被氯或溴取代。发现化合物13ff [[7-溴-3-（2-氟苯基）-1，2-苯并恶唑-6-基]氧基]乙酸（HP 522）在黑猩猩中具有中等尿酸尿酸，因此被选择用于进一步开发。
