Deep eutectic solvent mediated synthesis of 3,4-dihydropyrimidin-2(1H)-ones and evaluation of biological activities targeting neurodegenerative disorders
1 h and 1c were the most active monoamineoxidase A (MAO A) (IC50 = 0.31 ± 0.11 µM) and monoamineoxidaseB (MAO B) (IC50 = 0.34 ± 0.04 µM) inhibitors respectively. All compounds were selective AChE inhibitors and did not inhibit BChE (<29% inhibition). Compound 1 k (IC50 = 0.13 ± 0.09 µM) was the most active AChE inhibitor.
总是希望用“绿色”和“可持续”的替代反应介质替代危险且通常有害的有机溶剂。离子液体 (IL) 已成为有价值且用途广泛的液体,可在各种合成中替代大多数有机溶剂。然而,最近被称为深共晶溶剂 (DES) 的新型低熔点混合物已被用于有机合成。DES本质上不挥发,具有足够的热稳定性,还具有回收再利用的能力。因此,DES 已被用作替代反应介质来执行不同的有机反应。用于有机合成的绿色、廉价且易于处理的替代溶剂的可用性仍然稀缺,因此我们对 DES 介导的合成感兴趣。H ) 的。单胺氧化酶和胆碱酯酶是治疗阿尔茨海默病、帕金森病、抑郁症和焦虑症等各种神经系统疾病的重要药物靶点。评估了本文合成的化合物对这些酶的抑制潜力。一些化合物被发现是高效和选择性的抑制剂。化合物1 h和1c分别是最活跃的单胺氧化酶 A (MAO A) (IC 50 = 0.31 ± 0.11 µM) 和单胺氧化酶 B (MAO B) (IC

We herein reported the synthesis of dihydropyrimidines 1 and 2 on the basis of nitro and brominated salicylaldehyde derivatives by Biginellireaction in microwave conditions in the presence of cheap low toxic copper triflate. The structures of both compounds were investigated by the X-ray single-crystal diffraction method. The presence of non-covalent interactions and their impact on crystal structure
