NSAIDS are the first drug of choice in the treatment of inflammation has several side effects and still there is a need to introduce a new effective agent. In the present study, N-acylhydrazones bearing thiophene moiety were synthesized by applying bioisosterism drug design tool, characterized, screened for anti-inflammatory, analgesic activity and molecular docking using GLIDE. All the compounds viz., 2-benzamido-N’-(substituted)-3-(thiophen-2-yl)acrylohydrazides (4a-l) were synthesized by the microwave irradiation of compound 2-(benzamido)-3-(thiophen-2-yl)acrylohydrazide (3) with different aromatic/heteroaromatic aldehydes in acidic conditions by microwave irradiation and characterized by IR, 1H & 13C NMR, Mass spectra, followed by elemental analysis. Compound 4j showed slightly superior anti-inflammatory and analgesic activity (76 and 64 %) than standard (73 %, 62 %). The above results were supported by molecular docking studies done by using COX-2 protein revealed, compound (4j,4d) have -9.77, -9.58 as docking score which is higher than standard (-7.18). The present study concludes the potentiality of acylhydrazones to further developed as effective anti-inflammatory agents.
非甾体抗炎药是治疗炎症的首选药物,但具有多种副作用,因此仍需引入新的有效药物。在本研究中,通过应用生物等排体药物设计工具合成了含噻吩结构的N-酰基脲,并对其进行了表征、抗炎镇痛活性筛选和分子对接(使用GLIDE软件)。所有化合物,即2-苯甲酰胺基-N'-(取代)-3-(噻吩-2-基)丙烯酰肼(4a-l),均通过微波辐射条件下,将化合物2-(苯甲酰胺基)-3-(噻吩-2-基)丙烯酰肼(3)与不同的芳香/杂芳香醛在酸性条件下进行微波辐射合成,并通过IR、1H & 13C NMR、质谱以及元素分析进行表征。化合物4j显示出略优于标准的抗炎镇痛活性(76%和64%),而标准为73%和64%。上述结果通过使用COX-2蛋白质进行的分子对接研究得到支持,化合物(4j,4d)的对接得分分别为-9.77和-9.58,高于标准(-7.18)。本研究得出结论,酰基脲具有进一步开发为有效抗炎药物的潜力。
