A new series of pyrano[3,2‐c]pyridines, pyrazolo[4,3‐c]pyridines, and pyrido[4,3‐d]pyrimidines were synthesized and screened for their in vitro antioxidant activity. Compounds 13, 14, 15, 23, 29, 30, and 31 exhibited the most active oxygen free‐radical scavenger activity with percentage inhibitions of 99.4, 99.6, 99.8, 97.3, 99.0, 99.3, and 99.5 %; respectively, which is comparable to the curcumin
合成了一系列新的吡喃并[3,2-c]吡啶、吡唑并[4,3-c]吡啶和吡啶并[4,3-d]嘧啶,并筛选了它们的体外抗氧化活性。化合物 13、14、15、23、29、30 和 31 表现出最活跃的氧自由基清除剂活性,抑制百分比分别为 99.4、99.6、99.8、97.3、99.0、99.3 和 99.5%;分别与姜黄素的效力相当。大多数测试的化合物被证明对外周多核中性粒细胞 (PMN) 是安全的。报告了详细的合成和抗氧化活性数据。
