摘要:α-酮戊二酸(α-KA)是人体三羧酸循环的一个重要代谢中间体,异柠檬酸脱氢酶-1(IDH1)及异柠檬酸脱氢酶-2(IDH2)的突变将导致α-KA转化为2-羟基戊二酸(2HG),该过程与急性骨髓性白血病(AML)密切相关,因此检测人体内α-KA的含量变化具有重要意义。本文以罗丹明B作为荧光基团,通过将罗丹明B与水合肼反应得到能够检测α-KA的荧光增强型探针RBN,并优化了检测温度、pH及响应时间等条件。研究表明,RBN对α-KA表现出很好的选择性,不受人体内常见氨基酸、化学结构类似的羰基化合物及活性氧化物(ROS)的影响,具有潜在的应用价值。
As a dicarboxyl metabolite produced by living cells,α-ketoglutaratc acid (α-KA) can be converted to 2-hydroxyglutarate (2HG) which is confirmed to be associated with the acute myeloid leukemia (AML).In this paper,a rhodamine B-based turn-on fluroescent sensor for α-KA has been designed and synthesized,which is consist of rhodamine-B and hydrazino group.After a series of parallel optimization such as response time,pH and temperature,RBN shows an obvious turn-on fluorescence response to α-KA.In addition,the sensor exhibits good selectivity towards α-KA among 20 common amino acids,various dicarbonyl derivatives and reactive oxygen species.
