  发现苯并咪唑衍生物作为具有葡萄糖消耗改善活性的有效和选择性醛脱氢酶 1A1 (ALDH1A1) 抑制剂

  摘要：

  醛脱氢酶 1A1 (ALDH1A1) 在许多领域发挥重要的生理和毒理学功能，如中枢神经系统、炎症、代谢紊乱和癌症。已公开 ALDH1A1 的过度表达在肥胖、糖尿病和其他疾病中发挥重要作用，表明可能需要鉴定和开发小分子 ALDH1A1 抑制剂。在此，设计、合成和评价了一系列苯并咪唑衍生物。其中，化合物21，27，29，61和65表现出优异的抑制活性对ALDH1A1带IC 50在低微摩尔范围内的值和对 ALDH1A2、ALDH1A3、ALDH2 和 ALDH3A1 的高选择性。此外，一项体外研究表明，所有五种化合物都有效地改善了 HepG2 细胞的葡萄糖消耗，其中10 µM 的61和65产生的葡萄糖消耗与1 mM 的阳性对照二甲双胍(Met)产生的葡萄糖消耗几乎相等。此外，61和65在人肝微粒体中表现出理想的代谢稳定性。所有这些结果表明61和65适合进一步研究。

  Forty-three 1,5-diheteroaryl-1,4-pentadien-3-ones were designed as potential curcumin mimics, structurally featuring a central five-carbon dienone linker and two identical nitrogen-containing aromatic rings. They were synthesized using a Horner-Wadsworth-Emmons reaction as the critical step and evaluated for their cytotoxicity and antiproliferative activities toward both androgen-insensitive and androgen-sensitive prostate cancer cell lines and an aggressive cervical cancer cell line. Most of the synthesized compounds showed distinctly better in vitro potency than curcumin in the four cancer cell lines. The structure-activity data acquired from the study validated (1E,4E)-1,5-dihereroaryl-1,4-pentadien-3-ones as an excellent scaffold for in-depth development for clinical treatment of prostate and cervical cancers. 1-Alkyl-1H-imidazol-2-yl, ortho pyridyl, 1-alkyl-1H-benzo[d]imidazole-2-yl, 4-bromo-1-methyl-1H-pyrazol-3-yl, thiazol-2-yl, and 2-methyl-4-(trifluoromethyl)thiazol-5-yl were identified as optimal heteroaromatic rings for the promising in vitro potency. (1E,4E)-1,5-Bis(2-methyl-4-(trifluoromethyl)thiazol-5-yl)penta-1,4-dien-3-one, featuring thiazole rings and trifluoromethyl groups, was established as the optimal lead compound because of its good in vitro potency and attractive in vivo pharmacokinetic profiles.

  Diabetes mellitus is a chronic metabolic disorder that affects more than 180 million people worldwide. Peroxisome proliferator activated receptors (PPARs) are a group of nuclear receptors that have been targeted by the thiazolidinedione (TZD) class of compounds for the management of type II diabetes. PPAR gamma is known to regulate adipogenesis and glucose metabolism. Another emerging target for the design of antidiabetic agents is the free fatty acid receptor 1 (FFAR1), previously known as GPR40. Agonists of this receptor were found to enhance insulin secretion in diabetic patients. It has been reported that some thiazolidinediones (TZDs) activate FFAR1 with micromolar potency. In this study, based on docking studies into the crystal structure of PPAR gamma and a homology model of FFAR1, nineteen compounds were designed, synthesized, and biologically tested for agonistic activity on both receptors. Nine compounds showed promising dual activity, with two compounds, 11a and 5b, having affinities in the low micromolar range on both targets. These molecules represent the first antidiabetic agents that could act as insulin sensitizers as well as insulin secretagogues. (C) 2015 Elsevier Masson SAS. All rights reserved.
