• Effects of the Distance between Radical Sites on the Reactivities of Aromatic Biradicals

  separated further than that does no coupling occur. The most reactive radical site of each biradical was experimentally determined to be the one predicted to be more reactive based on the monoradical reactivity data. Therefore, the calculated vertical electron affinities of relevant monoradicals can be used to predict which radical site is most reactive in the biradicals.

  已知异构苯并炔中自由基位点的偶联会阻碍其自由基反应性。为了确定自由基位点必须相隔多远才能使其不相互作用，研究了几种基于异构体的质子化（异）喹啉和a啶基双自由基的气相反应性。发现所有（异）喹啉鎓基双自由基的反应均比具有相似垂直电子亲和力（即相似的极性效应）的相关单自由基反应慢。与之形成鲜明对比的是，the啶基双基自由基的自由基位置远比（异）喹啉鎓基体系中的自由基位置远，其相关反应性高于具有相似垂直电子亲和力的相关单基自由基。这些双自由基中两个自由基位置之间的距离较大，导致自旋-自旋耦合极少或没有，并且未观察到自由基反应性的抑制。因此，如果自由基位点位于相邻的苯环上并且仅在进一步分离之后才相互作用，否则不会发生偶联。根据单自由基反应性数据，通过实验确定每个双自由基的最高反应性自由基位点是预测为更具反应性的自由基。因此，所计算的相关基团的垂直电子亲和力可用于预测哪个基团在双基团中最具有反应性。根

• Hypoxia-Selective Antitumor Agents. 15. Modification of Rate of Nitroreduction and Extent of Lysosomal Uptake by Polysubstitution of 4-(Alkylamino)-5-nitroquinoline Bioreductive Drugs
  作者：Bronwyn G. Siim、Graham J. Atwell、Robert F. Anderson、Peter Wardman、Susan M. Pullen、William R. Wilson、William A. Denny

  Studies have shown that 4-(alkylamino)-5-nitroquinolines possess high selectivity (20-60-fold) for hypoxic tumor cells in vitro, but are not active as hypoxia-selective cytotoxins (HSCs) in vivo. The compounds show inadequate rates of extravascular diffusion, likely due both to sequestration of the bisbasic compounds into lysosomes and rapid nitroreduction. A further series of analogues, designed to counteract these limitations, has been synthesized and evaluated. Analogues bearing one to three electron-donating substituents on the quinoline have one-electron reduction potentials up to 100 mV lower than that of the unsubstituted compound (5), but do not have improved biological activity. The relationship between hypoxic selectivity and rates of metabolic reduction suggests at least two mechanisms of cytotoxicity for this series of 5-nitroquinolines. Compounds with high rates of reduction are toxic via oxygen-sensitive net bioreduction, while compounds which are poor substrates for nitroreduction are toxic through an oxygen-insensitive non-bioreductive mechanism. As rates of metabolic reduction are lowered, the non-bioreductive mechanism of toxicity becomes dominant and hypoxic selectivity is lost. A small series of analogues bearing hydrophilic but neutral side chains were also prepared. Compounds with a dihydroxypropyl side chain retained cytotoxic potency and hypoxic cell selectivity in cell culture assays, and had lowered uptake into lysosomes, but none of three analogues evaluated against KHT tumors in mice showed activity as an HSC in vivo.
