new thienyl-substituted pyrazoline benzenesulfonamides were synthesized and their carbonicanhydrase (CA, EC 4.2.1.1) inhibitory activities were tested on the human (h) isoforms hCA I and hCA II. The inhibition constant (Ki) of these sulfonamides were in the range of 232.16-637.70 nM toward the slow cytosolic isozyme hCA I, and in the range of 342.07-455.80 nM toward hCA II. Many of these compounds showed

addition, bearing a 2-thienyl group at the 3-position, gave the only addition adduct at room temperature in 3 h, whereas the chalcones bearing the 2-furyl group at the 1-position gave an addition-cyclization product (1, 4-thiazepine) in the same conditions. The effect of the groups to the reaction was investigated by changing the 1- and 3-position groups. The chalcones bearing the 2-thienyl group at the 1-position

order to ascertain the binding interactions of the synthesized derivatives to the MAO-A target protein, molecular docking was employed which demonstrated the key interactions with the amino acid residues Asn181, Phe208, Tyr69, Tyr197, Tyr444 and Met445 at the binding site. In addition, the most active derivatives 2i and 2b showed some imperative conserved interactions of the PDB co-crystal ligand 2Z5X
通过使不同的芳族/杂芳族醛和酮发生反应,通过克莱森·史密特(Claisen Schmidt)缩合分两步反应,然后将生成的查耳酮与肼环合,合成了一系列3,5-二取代-2-吡唑啉衍生物(2a – 2t)使用常规方法和微波方法在碱存在下将水合。通过各种物理化学方法对合成的衍生物进行了表征,并通过红外,质谱,1 H-NMR,13 C-NMR光谱数据和元素分析确定了它们的化学结构。使用合适的动物模型评估了具有尾部悬浮试验和强迫游泳试验的抗抑郁药以及具有Elevated Plus Maze试验活性的抗焦虑药。化合物2i和2j通过减少两种试验中的固定时间来显示出显着的抗抑郁活性,而化合物2a和2b被发现具有良好的抗焦虑活性,方法是增加试验剂量下的手臂进入次数和开放手臂探索时间( 50和100 mg / kg bw),分别与标准药物丙咪嗪和地西epa相比。为了确定合成的衍生物与MAO-A靶蛋白的结合相互作

interactions of these compounds with the amino acid residues Ala68, Tyr69, Phe208, Tyr407 and Tyr444. Moreover, synthesized derivatives showed encouraging pharmacokinetic (ADME) and toxicological (neurotoxicity, carcinogenicity, mutagenicity, reproductive toxicity, irritancy and acute toxicity) parameters as predicted by computational programs. Some of these toxicity studies were further examined in wet
用常规和微波辅助合成方法,用4-硝基苯磺酰氯取代2-吡唑啉核的N1位置,以可观的产率合成了一系列的1,3,5-三取代-2-吡唑啉衍生物(3a – 3t)。诸如IR,质谱,1 H-NMR和13 C-NMR的理化和光谱表征以及元素分析确保了所提出衍生物的形成。药理研究表明,化合物3d表现出最高的抗抑郁活性,但是化合物3l与对照组相比,在被测剂量(50和100 mg / kg bw)下,被发现是最有效的抗焦虑药。分子对接模拟建立了其神经药理作用的可能机制,对MAO-A蛋白具有令人钦佩的亲和力。这些化合物与氨基酸残基Ala68,Tyr69,Phe208,Tyr407和Tyr444的某些关键相互作用也证明了这一点。此外,合成衍生物显示出令人鼓舞的药代动力学(ADME)和毒理学(神经毒性,致癌性,诱变性,生殖毒性,刺激性和急性毒性)参数,如计算程序所预测。根据OECD指南,通过完成行为神经毒性研究和急
