  Factor Xa inhibitors based on a 2-carboxyindole scaffold: SAR of neutral P1 substituents

  摘要：

  A series of novel, highly potent 2-carboxyindole-based factor Xa inhibitors is described. Structural requirements for neutral ligands, which bind in the S1 pocket of factor Xa were investigated with the 2-carboxyindole scaffold. This privileged fragment assembly approach yielded a set of equipotent, selective inhibitors with structurally diverse neutral P1 substituents. (C) 2004 Elsevier Ltd. All rights reserved.

  摘要：

  Sirt2 是治疗神经、代谢和年龄相关疾病（包括癌症）的靶点。在这里，我们报告了一系列基于 1,2,4-恶二唑支架的 Sirt2 抑制剂。这些化合物是有效的 Sirt2 抑制剂，通过使用 Sirt2 底物 α-tubulin-acetylLys40 肽，在个位数 μM 水平上具有活性，对 Sirt1、-3 和 -5（脱乙酰酶和脱琥珀酰酶活性）无活性高达 100 μM。它们的抑制机制对肽底物和 NAD +都没有竞争性，与 Sirt2 和 ADP-核糖复合的 1,2,4-恶二唑类似物的晶体结构揭示了它在一个尚未开发的亚腔中的方向，可用于进一步的抑制剂开发. 在白血病细胞系35和39中测试48 小时后 10 或 25 μM 诱导细胞凋亡和/或显示抗增殖作用。蛋白质印迹分析证实了 Sirt2 抑制对 NB4 和 U937 细胞的影响。我们的结果为进一步改进抑制剂提供了具有紧凑支架和结构见解的新型 Sirt2

• Discovery of 1,2,4-Oxadiazole Derivatives Containing Haloalkyl as Potential Acetylcholine Receptor Nematicides

  Plant-parasitic nematodes pose a serious threat to crops and cause substantial financial losses due to control difficulties. Tioxazafen (3-phenyl-5-thiophen-2-yl-1,2,4-oxadiazole) is a novel broad-spectrum nematicide developed by the Monsanto Company, which shows good prevention effects on many kinds of nematodes. To discover compounds with high nematocidal activities, 48 derivatives of 1,2,4-oxadiazole were obtained by introducing haloalkyl at the 5-position of tioxazafen, and their nematocidal activities were systematically evaluated. The bioassays revealed that most of 1,2,4-oxadiazole derivatives showed remarkable nematocidal activities against Bursaphelenchus xylophilus, Aphelenchoides besseyi, and Ditylenchus dipsaci. Notably, compound A1 showed excellent nematocidal activity against B. xylophilus with LC50 values of 2.4 μg/mL, which was superior to that of avermectin (335.5 μg/mL), tioxazafen (>300 μg/mL), and fosthiazate (436.9 μg/mL). The transcriptome and enzyme activity results indicate that the nematocidal activity of compound A1 was mainly related to the compound which affected the acetylcholine receptor of B. xylophilus.

  植物寄生线虫对作物构成严重威胁，由于控制难度大，导致巨大的经济损失。Tioxazafen（3-苯基-5-噻吩-2-基-1,2,4-噁二唑）是由孟山都公司开发的一种新型广谱线虫杀虫剂，对许多种线虫表现出良好的预防效果。为了发现具有高线虫杀活性的化合物，通过在tioxazafen的5位引入卤代烷基，得到了48种1,2,4-噁二唑衍生物，并对其线虫杀活性进行了系统评估。生物测定表明，大多数1,2,4-噁二唑衍生物对松材线虫、贝氏线虫和葡萄球菌线虫表现出显著的线虫杀活性。值得注意的是，化合物A1对松材线虫表现出优异的杀虫活性，其LC50值为2.4μg/mL，优于阿维菌素（335.5μg/mL）、tioxazafen（>300μg/mL）和富丝噻唑（436.9μg/mL）。转录组和酶活性结果表明，化合物A1的线虫杀活性主要与化合物影响松材线虫的乙酰胆碱受体有关。

• Antikinetoplastid activity of 3-aryl-5-thiocyanatomethyl-1,2,4-oxadiazoles

  A series of 5-thiocyanatomethyl- and 5-alkyl-3-aryl-1,2,4-oxadiazoles were synthesized and evaluated for their activity against kinetoplastid parasites. Formation of the oxadiazole ring was accomplished through the reaction of benzamidoximes with acyl chlorides, while the thiocyanate group was inserted by reacting the appropriate 5-halomethyl oxadiazole with ammonium thiocyanate. The thiocyanate-containing compounds possessed low micromolar activity against Leishmania donovani and Trypanosoma brucei, while the 5-alkyl oxadiazoles were less active against these parasites. 3-(4-Chlorophenyl)-5-(thiocyanatomethyl)-1,2,4-oxadiazole (compound 4b) displayed modest selectivity for L. donovani axenic amastigote-like parasites over J774 macrophages, PC3 prostate cancer cells, and Vero cells (6.4-fold, 3.8-fold, and 9.1-fold, respectively), while 3-(3,4-dichlorophenyl)-5-(thiocyanatomethyl)-1,2,4-oxadiazole (compound 4h) showed 30-fold selectivity against Vero cells but was not selective against PC3 cells. In a murine model of visceral leishmaniasis, compound 4b decreased liver parasitemia caused by L. donovani by 48% when given in five daily i.v. doses at 5 mg/kg and by 61 % when administered orally for 5 days at 50 mg/kg. These results indicate that aromatic thiocyanates hold promise for the treatment of leishmanial infections if the selectivity of these compounds can be improved. (C) 2004 Elsevier Ltd.
