  The cysteine protease falcipain-2 (FP-2) of Plasmodium falciparum is a principal cysteine protease and an essential hemoglobinase of erythrocytic P. falciparum trophozoites, making it become an attractive target enzyme for developing anti-malarial drugs. In this study, a series of novel small molecule FP-2 inhibitors have been designed and synthesized based on compound 1, which was identified by using structure-based virtual screening in conjunction with an enzyme inhibition assay. All compounds showed high inhibitory effect against FP-2 with IC50s of 1.46-11.38 μM, and the inhibitory activity of compound 2a was ~2 times greater than that of prototype compound 1. The preliminary SARs are summarized and should be helpful for future inhibitor design, and the novel scaffold presented here, with its potent inhibitory activity against FP-2, also has potential application in discovery of new anti-malarial drugs.

  恶性疟原虫 (Plasmodium falciparum) 半胱氨酸蛋白酶 (falcipain-2， FP-2) 是原生质型疟原虫的主要半胱氨酸蛋白酶和必须的血红蛋白酶，这使得它成为研制抗疟药物的一个有吸引力的靶标酶。在本研究中，我们基于用酶抑制法结合基于结构的虚拟筛选得到的化合物 1，设计并合成了系列新型小分子 FP-2 抑制剂。所有化合物均为 FP-2的高效抑制剂，其半抑制浓度 (IC50) 值范围为 1.46 至 11.38 μM，化合物 2a 的抑制活性是母体化合物 1 的 2倍左右。本研究概括总结的初步构效关系将有助于未来抑制剂的设计，这里展示的新骨架以其对 FP-2的强效抑制活性，在发现新型抗疟药物方面也具有潜在的应用价值。

  Obwohl die Funktion von Kainat-Rezeptoren im Hirn aktuell noch nicht vollständig geklärt ist, werden diese in der Literatur zunehmend als neue Zielobjekte bei der Entwicklung originärer Antiepileptika definiert. Die von uns synthetisierten Thienopyrimidine wurden auf eine antagonistische Wirkung an den Kainat-Rezeptor-Subtypen GluR5 und GluR6 untersucht. Die beste Wirkung erzielte ein 4-Ethoxy-thieno[2,3-d]pyrimidin mit einem IC50 von 68 μM am GluR6-Rezeptor. Thieno[2,3-d]pyrimidines as antagonists of the glutamate receptors Although the function of the kainate receptors in the brain is still not clear, they are increasingly defined as targets in the development of new classes of anti-epileptics. The thienopyrimidines described in this report were tested for their antagonistic effect at the kainate receptor subtypes GluR5 and GluR6. The highest effectiveness was obtained by a 4-ethoxy-thieno[2,3-d]pyrimidin with an IC50 = 68 μM at the GluR6 receptor.

  recombinant ExoS ADPRT domain. Herein, we report structure–activity relationships of this compound class by comparing a total of 51 compounds based on a thieno [2,3-d]pyrimidin-4(3H)-one and 4-oxo-3,4-dihydroquinazoline scaffolds. Improved inhibitors with in vitro IC50 values of 6 μM were identified. Importantly, we demonstrated that the most potent inhibitors block ADPRT activity of native full-length

  在感染期间，革兰氏阴性机会性病原体铜绿假单胞菌利用其III型分泌系统将毒素外切酶S（ExoS）转移到真核宿主细胞的细胞质中。ExoS是一种必不可少的体内毒力因子，可使铜绿假单胞菌避免吞噬作用并最终杀死宿主细胞。ExoS主要通过ADP-核糖基转移酶（ADPRT）活性引起其致病性。我们最近鉴定了具有体外IC 50的新型ExoS ADPRT抑制剂使用重组ExoS ADPRT结构域进行酶促测定时，大约20μM的核酸。在这里，我们通过比较基于噻吩并[2,3- d ]嘧啶-4（3 H）-one和4-oxo-3,4-dihydroquinazoline支架的51种化合物来报告该化合物类别的结构-活性关系。鉴定出体外IC 50值为6μM的改良抑制剂。重要的是，我们证明了最有效的抑制剂在酶促试验中能阻断铜绿假单胞菌分泌的天然全长ExoS的ADPRT活性，IC 50值为1.3μM 。该化合物类别有望成为开发新型抗菌剂的起点。
