are as defined herein, as inhibitors of glutaminyl cyclase (QC, EC 2.3.2.5). QC catalyzes the intramolecular cyclization of N-terminal glutamine residues into pyroglutamic acid (5-oxo-prolyl, pGlu*) under liberation of ammonia and the intramolecular cyclization of N-terminal glutamate residues into pyroglutamic acid under liberation of water.

A series of novel hydroxyethylaminomethylbenzimidazole analogs 5a-y were synthesized and evaluated for their IL-5 inhibitory activity using pro-B Y16 cell line. Among them, 2-(((4-(cyclohexylmethoxy)-1H-benzo[d]imidazol-2-yl)methyl)amino)butan-1-ol (5e, 94.3% inhibition at 30 μM, IC50 = 3.5 μM, cLogP = 4.132) and 3-cyclohexyl-2-(((4-(cyclohexylmethoxy)-1H-benzo[d]imidazol-2-yl)methyl)amino) propan-1-ol
合成了一系列新颖的羟乙基氨基甲基苯并咪唑类似物5a-y,并使用pro-B Y16细胞系评估了它们的IL-5抑制活性。其中,2-((((4-(环己基甲氧基)-1 H-苯并[ d ]咪唑-2-基)甲基]氨基)氨基)丁丹-1-醇(5e, 30μM时94.3%抑制,IC 50 = 3.5 μM,cLogP = 4.132)和3-环己基-2-((((4-(环己基甲氧基)-1 H-苯并[ d ]咪唑-2-基)甲基]氨基)氨基)丙-1-醇(5k, 94.7%抑制30μM时,IC 50 =5.0μM,cLogP = 6.253)显示出最有效的抑制活性。SAR的基本特征(图5)表明,苯并咪唑环可被苯并咪唑环取代,以保持抑制活性。另外,羟乙基氨基甲基基团适合IL-5抑制活性。而且,碳上的疏水取代基在这些类似物的IL-5抑制活性中起重要作用。但是,N-取代的类似物没有改善抑制活性。此外,用正常的B淋巴母细胞对
