  Structure–activity relationship study of novel tissue transglutaminase inhibitors

  摘要：

  Thieno[2,3-d]pyrimidin-4-one acylhydrazide derivatives were discovered as moderately potent inhibitors of TGase 2 (tissue transglutaminase) utilizing a fluorescence-based assay that measured TGase 2 catalyzed incorporation of the dansylated Lys derivative alpha-N-Boc-Lys-CH2-CH2-dansyl into the protein substrate N,N-dimethylated-casein. A SAR study revealed that the acylhydrazide thioether side-chain and the thiophene ring were critical to inhibitory activity. (c) 2005 Elsevier Ltd. All rights reserved.

  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。
