design and synthesis of 10 novel N'-arylidene pyrazole-3-carbohydrazides are described. Compounds were pretended to act as dual agents against diabetes and oxidative stress, two correlated pathologies involved in metabolic syndrome development and progression. The antioxidant capacity was evaluated by means of DPPH and FRAP in vitro assays. It was found that compounds bearing a hydroxyl group at 4-position
在此,描述了10种新颖的N'-亚芳基吡唑-3-碳酰肼的设计和合成。化合物被认为是对抗糖尿病和氧化应激的双重药物,氧化应激是代谢综合征发展和进程的两个相关病理。抗氧化剂能力通过DPPH和FRAP体外测定来评估。发现在at部分的4-位带有羟基的化合物是有效的抗氧化剂实体,是活性最高的化合物3g(丁醛醛衍生物)。另外,确定了类似物的体内降血糖作用。关于上述,肉桂醛衍生物显示出稀缺的生物学活性,而4-羟基类似物在给药后7小时显示出较高的血糖降低。有趣的是,在降低血浆葡萄糖方面,最有效的抗氧化剂3b和3g也是活性最高的化合物,在3g的情况下,可达到减少量的80%。提出了分子对接结合姿势以对生物学结果进行合理解释,并提出羟基与CB1R的Asn287之间可能的相互作用是增强观察到的活性的重要特征。
