  Inhibitors for Human Glutaminyl Cyclase by Structure Based Design and Bioisosteric Replacement

  摘要：

  The inhibition of human glutaminyl cyclase (hQC) has come into focus as a new potential approach for the treatment of Alzheimer's disease. The hallmark of this principle is the prevention of the formation of A beta(3,11(pE)-40,42), as these A beta-species were shown to be of elevated neurotoxicity and likely to act as a seeding core leading to an accelerated formation of A beta-oligomers and fibrils. Starting from 1-(3-(1H-imidazol-1-yl)propyl)-3-(3,4-dimethoxyphenyl)thiourea, bioisosteric replacements led to the development of new classes of inhibitors. The optimization of the metal-binding group was achieved by homology modeling and afforded a first insight into the probable binding mode of the inhibitors in the hQC active site. The efficacy assessment of the hQC inhibitors was performed in cell culture, directly monitoring the inhibition of A beta(3,11(pE)-40,42) formation.

  Design, Synthesis, X-ray Crystallographic Analysis, and Biological Evaluation of Thiazole Derivatives as Potent and Selective Inhibitors of Human Dihydroorotate Dehydrogenase

  摘要：

  Human dihydroorotate dehydrogenase (HsDHODH) is a flavin-dependent mitochondrial enzyme that has been certified as a potential therapeutic target for the treatment of rheumatoid arthritis and other autoimmune diseases. On the basis of lead compound 4, which was previously identified as potential HsDHODH inhibitor, a novel series of thiazole derivatives were designed and synthesized. The X-ray complex structures of the promising analogues 12 and 33 confirmed that these inhibitors bind at the putative ubiquinone binding tunnel and guided us to explore more potent inhibitors, such as compounds 44, 46, and 47 which showed double digit nanomolar activities of 26, 18, and 29 nM, respectively. Moreover, 44 presented considerable anti-inflammation effect in vivo and significantly alleviated foot swelling in a dose-dependent manner, which disclosed that thiazole-scaffold analogues can be developed into the drug candidates for the treatment of rheumatoid arthritis by suppressing the bioactivity of HsDHODH.

  Structure-activity relationships for the cyanoguanidine portion of the lead cardiac selective ATP-sensitive potassium channel (KATP) opener (3) are described. The cyanoguanidine moity appears to be optimal since increasing or decreasing the distance between the aniline nitrogen and the pendant aromatic ring attenuates anti-ischemic potency/selectivity. Similarly, unfavorable results are obtained by replacement of

  描述了先导心脏选择性ATP敏感性钾通道（KATP）开放剂（3）氰基胍部分的结构活性关系。由于增加或减少苯胺氮与侧链芳香环之间的距离会减弱抗缺血能力/选择性，因此氰基胍活性似乎是最佳的。同样，通过用其他接头（CH2，S，O）代替苯胺氮也获得了不利的结果。用甲基取代苯环会降低心脏选择性。将尿素部分限制在苯并咪唑酮或咪唑啉酮环中可保持抗缺血性，并显着改善心脏选择性。如血管舒张药和抗缺血药的药效之比所示，体外心脏选择性变化超过三个数量级。这些数据与先前的结果一致，表明对于抗缺血和血管松弛活性存在不同的结构-活性关系。由于用结构上不同的KATP阻滞剂（格列本脲，5-羟基癸酸钠，甲氧芬那酸）预处理可取消该系列化合物的抗缺血作用，因此这些化合物的抗缺血作用机制似乎仍涉及开放KATP。
