A series of hybrids from diaryl-1,2,4-triazole and hydroxamic acid or N-hydroxyurea were synthesized and evaluated as novel anti-inflammatory agents. The biological data showed that (i) all the compounds showed dual COX-2/5-LOX inhibitory activities in vitro, and 15e showed optimal inhibitory activities (COX-2: IC50 = 0.15 μM, 5-LOX: IC50 = 0.85 μM), (ii) 15e selectively inhibited COX-2 relative to COX-1 with selectivity index (SI = 0.012) comparable to celecoxib (SI = 0.015), (iii) 15e exhibited potent anti-inflammatory activity (inhibition: 54.1%) which was comparable to the reference drug celecoxib (inhibition: 46.7%) in a xylene-induced ear edema assay, and (iv) 15e displayed promising analgesic activity in acetic acid-induced writhing response and hot-plate assay. Finally, a molecular modeling study revealed the binding interactions of 15e with COX-2 and 5-LOX. Our findings suggest that 15e may be a promising anti-inflammatory agent for further evaluation.
研究人员合成了一系列由二芳基-1,2,4-三唑和羟肟酸或 N-羟基脲组成的混合物,并将其作为新型抗炎剂进行了评估。生物数据显示:(i) 所有化合物在体外均显示出 COX-2/5-LOX 双重抑制活性,其中 15e 显示出最佳抑制活性(COX-2:IC50 = 0.15 μM,5-LOX:IC50 = 0.85 μM);(ii) 相对于 COX-1,15e 选择性地抑制 COX-2,其选择性指数(SI = 0.012)与塞来昔布(SI = 0.(iii)在二甲苯诱导的耳部水肿试验中,15e 表现出强大的抗炎活性(抑制率:54.1%),与参考药物塞来昔布(抑制率:46.7%)相当;(iv)在醋酸诱导的蠕动反应和热板试验中,15e 表现出良好的镇痛活性。最后,分子建模研究揭示了 15e 与 COX-2 和 5-LOX 的结合相互作用。我们的研究结果表明,15e 可能是一种很有前景的抗炎药物,值得进一步评估。
