the cognitive and behavioral symptoms. The utility of cholinergic replacement by acetylcholinesterase (AChE) inhibitors in AD treatment has been well-documented so far. Recent studies have also demonstrated that human carbonic anhydrases (hCAs) serve as important targets for AD treatment. In an attempt to identify potent AChE and hCA inhibitors, new thiazolyl-pyrazolines (3a-k) were designed based on
阿尔茨海默氏病(AD)是痴呆症的复杂,主要和进行性形式。AD的治疗取决于认知和行为症状。迄今为止,乙酰胆碱酯酶(AChE)抑制剂可替代胆碱能在AD治疗中的作用。最近的研究还表明,人类碳酸酐酶(h CA)可以作为AD治疗的重要靶标。为了鉴定有效的AChE和h CA抑制剂,新的噻唑基-吡唑啉(3a - k)是基于噻唑和吡唑啉支架的分子杂交设计的。一种简单而通用的合成方法,由三个步骤组成,即克莱森-施密特反应,2-吡唑啉环系统的形成以及汉茨噻唑的合成,可制备化合物3a - k。通过体外和直接酶法试验对合成的衍生物的功效进行了实验验证。此外,使用SchrödingerSuite软件对化合物进行计算机筛选,以基于Glide XP评分,MM-GBSA计算和验证来识别潜在化合物的结合亲和力。体外和计算机分析结果研究表明,化合物3a,3f和3d分别由于对AChE,h CA I和h CA II的显着影响而成为该系列中最有希望的衍生物。
Identification of a new class of potent aldose reductase inhibitors: Design, microwave-assisted synthesis, in vitro and in silico evaluation of 2-pyrazolines
Aldosereductase (AR) acts as a multi-disease target for the design and development of therapeutic agents for the management of diabetic complications as well as non-diabetic diseases. In the search for potent AR inhibitors, the microwave-assisted synthesis of twenty new compounds with a 1,3-diaryl-5-(4-fluorophenyl)-2-pyrazoline moiety as a common fragment in their structure (1–20) was carried out
