We investigated the superoxide anion scavenging effects of 2-amino-1,3- selenazoles and bis-(2-amino-5-selenazoyl) ketones using a highly sensitive quantitative chemiluminescence method. At 166 μM, the 2-amino-1,3-selenazoles and bis-(2-amino-5-selenazoyl) ketones scavenged in the range of 10.0 to 80.0% of O2−. Bis[2-dimethylamino-5-(1,3-selenazolyl)] ketone exhibited the strongest superoxide anion-scavenging activity among the six kinds of 2-amino-1,3-selenazoles and three kinds of bis-(2-amino-5-selenazoyl) ketones. The 50% inhibitory concentration (IC50) of bis[2-dimethylamino-5-(1,3-selenazolyl)] ketone was determined to be 37.1 μM. Thus, bis[2-dimethylamino-5-(1,3-selenazolyl)] ketone acted in vitro as effective and potentially useful O2− scavenger.
我们使用高灵敏度定量化学发光方法研究了 2-氨基-1,3-硒唑和双-(2-氨基-5-硒唑酰)酮的超氧阴离子清除作用。在 166 μM 下,2-氨基-1,3-硒唑和双-(2-氨基-5-硒酰基)酮可清除 10.0 至 80.0% 的 O2−。双[2-二甲氨基-5-(1,3-硒唑基)]酮在6种2-氨基-1,3-硒唑和3种双-(2-氨基-硒唑)中表现出最强的超氧阴离子清除活性。 5-硒酰基)酮。双[2-二甲氨基-5-(1,3-硒唑基)]酮的50%抑制浓度(IC50)测定为37.1 μM。因此,双[2-二甲氨基-5-(1,3-硒唑基)]酮在体外充当有效且潜在有用的O2−清除剂。
