Synthesis, Biological Evaluation, and Molecular Modeling of 1-Benzyl-1H-imidazoles as Selective Inhibitors of Aldosterone Synthase (CYP11B2)
摘要:
Reducing aldosterone action is beneficial in various major diseases such as heart failure. Currently, flits is achieved with mineralocorticoid receptor antagonists, however, aldosterone synthase (CYP11B2) inhibitors may offer a promising alternative. In this study, WC used three-dimensional modeling of CYP11B2 to model the binding modes of the natural substrate 18-hydroxycorticosterone and the recently published CYP11B2 inhibitor R-fadrozole as a rational guide to design 44 structurally simple and achiral 1-benzyl-1H-imidazoles. Their syntheses, in vitro inhibitor potencies, and in silico docking are described. Some promising CYP11B2 inhibitors were identified, with our novel lead MOERAS115 (4-((5-phenyl-1H-imidazol-1-y1)methyl)benzonitrile) displaying an IC50 for CYP11B2 of 1.7 nM, and a CYP11B2 (versus CYP11B1) selectivity of 16.5, comparable to R-fadrozole (IC50 for CYP11B2 6.0 nM. Selectivity 19.8). Molecular docking of the Inhibitors in the models enabled us to generate posthoc hypotheses oil their binding modes, providing a Valuable basis for future Studies and further design of CYP11B2 inhibitors.

are defined herein. Such compounds and compositions are useful for modulating an activity of indoleamine 2,3-dioxygenase; treating indoleamine 2,3-dioxygenase (IDO) mediated immunosuppression; treating a medical conditions that benefit from the inhibition of enzymatic activity of indoleamine -2,3-dioxygenase; enhancing the effectiveness of an anti-cancer treatment comprising administering an anti-cancer agent; treating tumor-specific immunosuppression associated with cancer; and treating immunosupression associated with an infectious disease.

extensive library of analogues was prepared using the Van Leusen three-component reaction, biological evaluation of which led to the identification of two analogues (26 and 32) with favorable anti-MRSA activity (MIC ≤ 0.25 µg/mL) which also lacked cytotoxic or hemolytic properties. The screening campaign also identified two derivatives, a phenethyl-indole-imidazole 57 and a 5-phenyl-1H-imidazole 111 that
抗生素能够治愈传染病并预防免疫功能低下者的感染,因此成为现代医学拯救生命的基石。它们的大量使用导致抗生素耐药细菌的发生率急剧增加,从而迫切需要具有新作用机制的抗生素。作为我们寻找新抗菌药物的一部分,我们筛选了内部化合物库,并确定了两种 3-取代-1 H -咪唑-5-基-1 H -吲哚作为弱生长抑制剂 (MIC 16 µg/mL)耐甲氧西林金黄色葡萄球菌(MRSA)。使用 Van Leusen 三组分反应制备了一个广泛的类似物库,对其进行生物学评估,鉴定出具有良好抗 MRSA 活性 (MIC ≤ 0.25 µg/mL) 且缺乏细胞毒性的两种类似物( 26和32 )或溶血特性。筛选活动还鉴定出两种衍生物,苯乙基吲哚咪唑57和 5-苯基-1 H-咪唑111 ,它们是针对新型隐球菌的无毒选择性抗真菌剂。这些结果已确定 3-取代-1 H -咪唑-5-基-1 H -吲哚和 5-苯基-1 H -咪唑作为新的结构支架,分别作为抗
