Ibuprofen phenylalanine derivatives 1-17 as new safe nonsteroidal anti-inflammatory drugs (NSAIDs) agents were synthesized and characterized depending on spectroscopic and analytical analyses. Starting from reaction between ibuprofen with PABA to have fussed derivative 1 that reacted with phenylalanine followed by hydrazine, ammonium thiocyanate, urea derivatives to afford the new compounds. For investigated drugs 1-17, molecular docking was done at the cyclooxygenase-2 (COX-2) active site. For the purpose of discussing binding affinity, the position with the lowest root-mean square deviation (RMSD) has been chosen. The binding interaction was enhanced by adding a hydrazide fragment to the parent molecule, as shown in the docking technique. Compounds 5, 6, 12, 16 and 17 were investigated as anti-inflammatory and analgesic drugs. Using a carrageenan-induced mice of hind paw edoema, we investigated the synthesized compounds' potential anti-inflammatory activity in contrast to their parent molecule, ibuprofen. The antinociceptive and the ulcerogenic effect of the synthesized compounds have been measure. Compounds 5 and 6 are the best drug analogues and these compounds could be promising for anti-inflammatory agents.
根据光谱和分析结果,我们合成了布洛芬苯丙氨酸衍生物1-17,并对其进行了表征,这些化合物是新型安全的非甾体抗炎药(NSAIDs)。首先,布洛芬与对氨基苯甲酸发生反应,生成衍生物1,然后与苯丙氨酸发生反应,再与肼、硫氰酸铵、尿素衍生物发生反应,生成新的化合物。对于研究药物1-17,我们在环加氧酶-2(COX-2)活性位点进行了分子对接。为了讨论结合亲和力,我们选择了均方根偏差(RMSD)最小的位置。对接技术显示,通过在母体分子中添加一个酰肼片段,可以增强结合相互作用。我们研究了化合物5、6、12、16和17作为抗炎和镇痛药物的作用。我们使用角叉菜胶诱导的小鼠后肢水肿模型,研究了合成化合物与母体分子布洛芬相比的潜在抗炎活性。我们测量了合成化合物的镇痛和溃疡作用。化合物5和6是最好的药物类似物,这些化合物有望成为抗炎药。
