  Synthesis and Antimicrobial Activities of Novel Series of 1-((4-Methyl-2-Substituted Thiazol-5-yl)Methyleneam INO)-2-Substituted Isothiourea Derivatives

  摘要：

  A novel series of 1-((4-methyl-2-substituted thiazol-5-yl)methyleneamino)-2-substituted isothiourea derivatives was synthesized by alkylation of (Z/E)-1-((4-methyl-2-substituted thiazol-5-yl)methylene)thiosemicarbazide with alkylhalide in acetone. All the newly synthesized compounds were characterized by spectral (IR, H-1 NMR, C-13 NMR, and mass spectrometry) methods. The newly synthesized compounds were screened for in vitro antimicrobial activity. Most of the compounds show moderate to excellent antimicrobial activity.

  Design and optimization of hybrid of 2,4-diaminopyrimidine and arylthiazole scaffold as anticancer cell proliferation and migration agents

  摘要：

  Therapeutics of metastatic or triple-negative breast cancer are still challenging in clinical. Herein we demonstrated the design and optimization of a series of hybrid of 2,4-diaminopyrimidine and arylthiazole derivatives for their anti-proliferative properties against two breast cancer cell lines (MCF-7 as human breast cancer and MDA-MB-231 as triple-negative breast cancer). More importantly, some of those compounds with potent antiproliferative activities also indicated excellent inhibitory activities against MDA-MB-231 cell migration. These results suggested that the new series of hybridation of arylthiazoles and aminopyrimidines could be identified and developed as novel highly potential anticancer agents against the triple-negative breast cancer as well as metastatic one in the future.

  The free fatty acid receptor 1 (FFA1/GPR40) has attracted interest as a novel target for the treatment of type 2 diabetes. Several series of FFA1 agonists including TAK-875, the most advanced compound terminated in phase III studies due to concerns about liver toxicity, have been hampered by relatively high molecular weight and lipophilicity. Aiming to develop potent FFA1 agonists with low risk of

  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。

  structure-activity relationship study based on the previleged scaffolds led to the discovery of 2-(4-[(2'-chloro-[1,1'-biphenyl]-3-yl)methoxy]phenyl)sulfonyl}acetic acid (compound 20), which showed a better balance than compound 2 in terms of physicochemical properties, cytotoxicity profiles and pharmacokinetic properties. Subsequent in vivo studies demonstrated that compound 20 robustly improves the

  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。
