  Small Molecule Inhibitors of Dynamin I GTPase Activity:  Development of Dimeric Tyrphostins

  摘要：

  Dynamin I is a GTPase enzyme required for endocytosis and is an excellent target for the design of potential endocytosis inhibitors. Screening of a library of tyrphostins, in our laboratory, against the GTPase activity of dynamin I gave rise to a mu M potent lead, 2-cyano-3-(3,4-dihydroxyphenyl)thioacrylamide (1, IC50 70 mu M). Our initial investigations suggested that only the dimeric form of 1 displayed dynamin I GTPase inhibitory activity. Subsequent synthetic iterations were based on dimeric analogues and afforded a number of small molecules, low mu M potent, inhibitors of dynamin I GTPase, in particular, symmetrical analogues with a minimum of two free phenolic -OHs: catechol-acrylamide (9) (IC50 = 5.1 +/- 0.6 mu M), its 3,4,5-trihydroxy congener (10) (IC50 = 1.7 +/- 0.2 mu M), and the corresponding 3-methyl ether (11) (IC50 = 9 3 mu M). Increasing the length of the central alkyl spacer from ethyl to propyl (22-24) afforded essentially identical activity with IC50'S of 1.7 0.2, 1.7 0.2, and 5 +/- 1 mu M, respectively. No decrease in activity was noted until the introduction of a hexyl spacer. Our studies highlight the requirement for two free amido NHs with neither the mono-N-methyl (86) nor the bis-N-methyl (87) analogues inhibiting dynamin I GTPase. A similar effect was noted for the removal of the nitrile moieties. However, modest potency was observed with the corresponding ester analogues of 9-11: ethyl ester (90), propyl ester (91), and butyl ester (92), with IC50'S of 42 3, 38 2, and 61 2 mu M, respectively. Our studies reveal the most potent and promising dynamin I GTPase inhibitor in this series as (22), which is also known as BisT.

  sheets in Aβ fibrils, showed good potency to inhibit Aβ(1–42) fibrillization. Furthermore, compound 2 effectively dissociated the Aβ(1–42) preformed fibrils. The cytotoxicity induced by Aβ(1–42) aggregates in human neuroblastoma was reduced in the presence of 2, and feeding 2 to Aβ transgenic C. elegans rescued the paralysis phenotype. In addition, the binding and stoichiometry of 2 to Aβ(1–40) were

  阿尔茨海默氏病（AD）的病理特征之一是由淀粉样β（Aβ）原纤维组成的细胞外老年斑。用小分子阻断Aβ自组装或分解Aβ聚集体将是治疗AD的潜在治疗策略。在这项研究中，我们合成了一系列合理设计的二价化合物，并研究了它们对Aβ原纤维化的影响。由两个咖啡酸分子组成的二价酰胺（2），其丙二胺连接基的长度约为5.0Å，与Aβ纤丝中相邻β片的距离接近，显示出良好的抑制Aβ（1-42）原纤维化的能力。 。此外，化合物2有效地解离了Aβ（1-42）预形成的原纤维。在2的存在下，Aβ（1-42）聚集体在人成神经细胞瘤中诱导的细胞毒性降低，向Aβ转基因秀丽隐杆线虫喂食2可挽救麻痹性表型。此外，使用电喷雾电离-旅行波离子迁移率-质谱法证明了2与Aβ（1-40）的结合和化学计量，同时进行了分子动力学模拟以了解Aβ（1-40）-的结构。2复杂。
