采用脉冲辐解技木,在pH=7的磷酸缓冲溶液中,以AQS为参比物,用动力学的方法测定了12个自行设计合成的新型放射增敏化合物的单电子还原电位值,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42651140&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42651142&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42651141&type=,,作为初步评价亲电子性化合物的增敏作用的指标之一。它们的单电子还原电位值,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42651143&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42651145&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42651144&type=,在-420~- 490 mV之间,表明这类化合物具有一定的亲电子性。
The value of one-electron reduction potential (,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42651146&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42651128&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42651147&type=,) is one of the important parameters of radiosensitive compounds with high electron affinity. By using anthraquinone-2-sulfate (AQS) as reference, the ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42651150&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42651154&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42651130&type=, of novel radiosensitizers, such as AZ, AC, EA, OAZ, OAC, OEA, mNAZ, mNAC, mNEA, pNAZ, pNAC, and, pNEA, were determined by pulse radiolysis. Their one-electron reduction potentials range from - 420 mV to -490mV.
