  新型噻唑类游离脂肪酸受体1激动剂用于2型糖尿病的设计，合成及构效关系研究

  摘要：

  游离脂肪酸受体1（FFA1 / GPR40）作为治疗2型糖尿病的新靶标已引起人们的关注。相对较高的分子量和亲脂性阻碍了包括FAK1激动剂在内的数个系列的FFA1激动剂（由于对肝毒性的担忧而在III期研究中终止的最先进的化合物）。为了通过降低亲脂性来开发具有低肝毒性风险的有效FFA1激动剂，TAK-875的中间苯基被11个极性五元杂芳族化合物所取代。随后，对SAR的系统探索和分子建模的应用导致了化合物44的鉴定，它是一种出色的FFA1激动剂，在正常和2型糖尿病小鼠中均具有强大的降血糖作用，即使在两倍摩尔的TAK-875剂量下也具有低血糖风险和肝毒性。同时，指出了两个重要发现。首先，我们的噻唑系列中的甲基占据了一个小的疏水亚口袋，与TAK-875没有相互作用。此外，激动活性显示与噻唑核心和末端苯环之间的二面角具有良好的相关性。这些结果促进了对配体结合口袋的了解，并可能有助于设计更有希望的FFA1激动剂。

The results displayed the test compounds significantly restrained ATP production of cancer cells. Overall, we have designed and synthesized a series of compounds which exhibited significant cytotoxicity against cancer cells and effectively inhibited mitochondrial energy production.

  线粒体是细胞维持必要代谢活动的关键能量生产来源。针对功能失调的线粒体特征一直是线粒体相关疾病研究的热点。对癌性线粒体代谢的研究是肿瘤治疗中持续关注的问题。在此，我们基于我们早期对线粒体靶向剂的研究，着手评估新型 TPP-噻唑衍生物家族的抗癌活性。具体而言，我们设计并合成了一系列 TPP-噻唑衍生物，并通过 MTT 测定显示大多数合成的化合物有效抑制了三种癌细胞系（HeLa、PC3 和 MCF-7）。在结构修改后，我们探索了 SAR 关系并确定了最有希望的化合物R13（IC50 of 5.52 μM) 用于进一步研究。同时，我们进行了 ATP 产生测定以评估所选化合物对 HeLa 细胞能量产生的抑制作用。结果显示测试化合物显着抑制癌细胞的ATP产生。总体而言，我们设计并合成了一系列对癌细胞具有显着细胞毒性并有效抑制线粒体能量产生的化合物。

  游离脂肪酸受体1（FFA1）已成为介导葡萄糖刺激的胰岛素分泌的有吸引力的抗糖尿病靶标。已经报道了几种FFA1激动剂，但是其中许多具有较高的亲脂性和/或分子量。在这里，我们描述了具有减少化合物2相关的亲脂性，细胞毒性和β-氧化的多重优势的砜-羧酸部分的鉴定。基于旧支架的进一步结构-活性关系研究导致发现了2-（（4-[（2'-氯-[1,1'-联苯] -3-基）甲氧基]苯基]磺酰基}乙酸（化合物20），显示出比化合物2更好的平衡在理化性质，细胞毒性特征和药代动力学性质方面。随后的体内研究表明，化合物20在正常模型和2型糖尿病模型中均能显着提高葡萄糖耐量，且无低血糖风险。与TAK-875诱发肝毒性的高风险相比，即使在较高剂量下，在化合物20的慢性毒性研究中也没有观察到明显的不良反应，例如肝和肾毒性。

  The free fatty acid receptor 1 (FFA1 or GPR40) and peroxisome proliferator-activated receptor delta (PPAR delta) have attracted a lot of attention due to their role in promoting insulin secretion and sensibility, respectively, which are two major features of diabetes. Therefore, the dual FFA1/PPAR delta agonists would increase insulin secretion and sensibility by FFA1 and PPAR delta activation. In this study, we hybrid FFA1 agonist AM-4668 with PPAR delta agonist GW501516, leading to the identification of orally bioavailable dual agonist 32, which revealed high selectivity over other PPAR delta. Moreover, compound 32 exhibited good pharmacokinetic profiles with high plasma concentration, sustained half-life and low clearance in vivo. During the hypoglycemic test, a dual agonist 32 enhanced the tolerance of ob/ob mice for glucose loading in a dose-dependent manner. Our results suggest that dual FFA1/PPAR delta agonist could be a valuable therapy for type 2 diabetes. (C) 2018 Elsevier Masson SAS. All rights reserved.

  A new series of 5-(1-benzyl-1H-1,2,3-triazol-4-yl)-4-methyl-2-arylthiazole derivatives, 6a-w have been synthesized by click reaction of substituted benzylazide, 5a-d with 5-ethynyl-4-methyl-2-substituted phenylthiazole, 4a-f. The starting compounds 4-ethynyl-2-substituted phenylthiazole (4a-f) were synthesized from the corresponding thiazole aldehyde by using the Ohira-Bestmann reagent. The structure of the synthesized compounds was determined by spectral analysis. All the synthesized compounds were screened for their preliminary antitubercular activity against Mycobacterium tuberculosis H37Ra (MTB, ATCC 25177). Most of the synthesized compounds reported good activity against M. tuberculosis H37Ra strain with IC50 range of 0.58-8.23 mu g/mL. Compounds 6g and 6k reported good antitubercular activity with MIC90 values of 4.71 and 2.22 mu g/mL, respectively. Potential antimycobacterial activity suggested that these compounds could serve as good lead compounds for further optimization and development of a newer antitubercular candidate.[GRAPHICS].
