BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) are the most widely administered drugs for the treatment of inflammation. However, they usually cause some unexpected side effects. Coumarins and their derivatives exhibit broad-spectrum biological activities. In order to develop new anti-inflammatory drugs with high anti-inflammatory activity and less side effects, a series of 9-substituted-9,10-dihydrochromeno[8,7-e][1,3]oxazin-2(8H)-one derivatives were designed, synthesized, and screened for their anti-inflammatory activities. METHODS We investigated the effect of compound 9-(2-chlorophenyl)-9,10-dihydrochromeno[8,7-e][1,3]oxazin-2(8H)-one (B3) on lipopolysaccharide (LPS)-induced cytokine levels in RAW 264.7 cells at concentrations between 6.25 μg/ml and 25 μg/ml. Concentrations of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were measured by enzyme-linked immunosorbent assay (ELISA). Moreover, mitogen-activated protein kinase (MAPK) and nuclear factor-κB (NF-κB) activation was investigated by western blot assay. RESULTS Compound B3 could inhibit inflammatory responses via suppression of the NF-κB and MAPK signaling pathways. Docking study of the prepared compounds was performed for the study of interaction of molecules with the active site of TNF-α. CONCLUSION 9,10-Dihydrochromeno[8,7-e][1,3]oxazin-2(8H)-one derivatives showed anti-inflammatory activity. Compound B3 was the most potent. The results of this study are encouraging further investigations to develop compound B3 as a novel therapeutic agent for inflammatory disorders.

9,10-二氢色素[8,7-e] [1,3]恶嗪-2(8H)-一衍生物作为有效的抗炎药的药理评价。

背景技术非甾体抗炎药(NSAID)是用于治疗炎症的最广泛施用的药物。但是,它们通常会引起一些意想不到的副作用。香豆素及其衍生物具有广谱的生物活性。为了开发具有高抗炎活性和较少副作用的新型抗炎药,一系列9-取代的9,10-二氢色素[8,7-e] [1,3] oxazin-2(8H)设计,合成和筛选了一种衍生物的抗炎活性。方法我们研究了化合物9-(2-氯苯基)-9,10-二氢色素[8,7-e] [1,3]恶嗪-2(8H)-一(B3)对脂多糖(LPS)诱导的影响浓度在6.25μg/ ml和25μg/ ml之间的RAW 264.7细胞中的细胞因子水平。通过酶联免疫吸附测定(ELISA)测量肿瘤坏死因子-α(TNF-α)和白介素-6(IL-6)的浓度。此外,通过蛋白质印迹法研究了有丝分裂原激活的蛋白激酶(MAPK)和核因子-κB(NF-κB)的激活。结果化合物B3可通过抑制NF-κB和MAPK信号通路抑制炎症反应。对制备的化合物进行对接研究,以研究分子与TNF-α活性位点的相互作用。结论9,10-二氢色素[8,7-e] [1,3]恶嗪-2(8H)-一衍生物具有抗炎作用。化合物B3是最有效的。这项研究的结果鼓舞了进一步的研究,以开发化合物B3作为炎症性疾病的新型治疗剂。此外,通过蛋白质印迹法研究了有丝分裂原激活的蛋白激酶(MAPK)和核因子-κB(NF-κB)的激活。结果化合物B3可通过抑制NF-κB和MAPK信号通路抑制炎症反应。对制备的化合物进行对接研究,以研究分子与TNF-α活性位点的相互作用。结论9,10-二氢色素[8,7-e] [1,3]恶嗪-2(8H)-一衍生物具有抗炎作用。化合物B3是最有效的。这项研究的结果鼓舞了进一步的研究,以开发化合物B3作为炎症性疾病的新型治疗剂。此外,通过蛋白质印迹法研究了有丝分裂原激活的蛋白激酶(MAPK)和核因子-κB(NF-κB)的激活。结果化合物B3可通过抑制NF-κB和MAPK信号通路抑制炎症反应。对制备的化合物进行对接研究,以研究分子与TNF-α活性位点的相互作用。结论9,10-二氢色素[8,7-e] [1,3]恶嗪-2(8H)-一衍生物具有抗炎作用。化合物B3是最有效的。这项研究的结果鼓舞了进一步的研究,以开发化合物B3作为炎症性疾病的新型治疗剂。结果化合物B3可通过抑制NF-κB和MAPK信号通路抑制炎症反应。对制备的化合物进行对接研究,以研究分子与TNF-α活性位点的相互作用。结论9,10-二氢色素[8,7-e] [1,3]恶嗪-2(8H)-一衍生物具有抗炎作用。化合物B3是最有效的。这项研究的结果鼓舞了进一步的研究,以开发化合物B3作为炎症性疾病的新型治疗剂。结果化合物B3可通过抑制NF-κB和MAPK信号通路抑制炎症反应。对制备的化合物进行对接研究,以研究分子与TNF-α活性位点的相互作用。结论9,10-二氢色素[8,7-e] [1,3]恶嗪-2(8H)-一衍生物具有抗炎作用。化合物B3是最有效的。这项研究的结果鼓舞了进一步的研究,以开发化合物B3作为炎症性疾病的新型治疗剂。
