• Thionations Using a P₄S₁₀−Pyridine Complex in Solvents Such as Acetonitrile and Dimethyl Sulfone
  作者：Jan Bergman、Birgitta Pettersson、Vedran Hasimbegovic、Per H. Svensson

  Tetraphosphorus decasulfide (P4S10) in pyridine has been used as a thionating agent for a long period of time. The moisture-sensitive reagent has now been isolated in crystalline form, and the detailed structure has been determined by X-ray crystallography. The thionating power of this storable reagent has been studied and transferred to solvents such as acetonitrile in which it has proven to be synthetically

  四硫化二磷（P 4 S 10）中的吡啶已长期用作硫代剂。现在已经以结晶形式分离出对水分敏感的试剂，并且已经通过X射线晶体学确定了详细的结构。已经研究了这种可储存试剂的去硫能力，并将其转移到诸如乙腈之类的溶剂中，在该溶剂中已证明其在合成上是有用的并且具有非凡的选择性。它的性能已经与所谓的Lawesson试剂（LR）进行了比较。特别有趣的是在相对较高的温度（约165°C）下以二甲基砜为溶剂进行硫磺化的结果。在这些条件下，例如，a啶酮和3-乙酰吲哚可以迅速转化为相应的亚硫代衍生物。甘氨酰甘氨酸类似地得到哌嗪去甲酮。在这些温度下 LR由于快速分解而效率低下。硫代产物通常更清洁并且更容易获得，因为在结晶试剂中，常规试剂P中始终存在杂质吡啶或LR中的4 S 10已被除去。

  compounds exhibited remarkable activity against MMC-resistant P388 in mice. FAB-MS spectra of these mitomycin derivatives showed the elimination of the C-6-methyl substituents from the mitomycin skeletons to form quinonemethides. Interestingly, treatment of 6-demethyl-6-[[(2-pyrimidinyl)thio]methyl ]mitomycin C (12v) with diethylamine afforded 6-demethyl-6-[(diethylamino)methyl]mitomycin C (31) in good

  合成了一系列C-6取代的甲基丝裂霉素，并评估了其抗细胞和抗肿瘤活性。这些新颖的化合物是通过将各种醇或硫醇迈克尔加成至6-去甲基-7,7-（乙二氧基）-6,7-二氢-6-亚甲基亚神经松脂中，然后用NH3或MeOH / K2CO3处理而制备的。大多数化合物对HeLa S3均有效，其中一些化合物对小鼠的P388白血病和肉瘤180显示出优于丝裂霉素C（MMC）的活性。此外，某些化合物对小鼠的MMM耐药P388表现出显着活性。这些丝裂霉素衍生物的FAB-MS光谱表明，从丝裂霉素骨架上消除了C-6-甲基取代基，从而形成了醌甲基化物。有趣的是 用二乙胺处理6-去甲基-6-[[[（2-嘧啶基）硫代]甲基]丝裂霉素C（12v）得到6-脱甲基-6-[[（二乙氨基）甲基]丝裂霉素C（31），收率高。这些结果表明，C-6取代的甲基丝裂霉素将具有与MMC不同的生物学特性。

  Screening of mesoionic compounds as potential electron acceptors by analogy with metronidazole led to the finding of in vitro antitrichomonal activity for anhydro-2-phenyl-3-hydroxythiazolo [3,2-a]pyridinium hydroxide (1). In a series of analogues, potent in vitro activity was found to be associated with amino substitution; however, such activity was dependent on specific structural features and not

  通过与甲硝唑类比筛选作为潜在电子受体的中离子化合物，发现了对脱水-2-苯基-3-羟基噻唑[3,2-a]吡啶鎓氢氧化物的体外抗滴虫活性（1）。在一系列类似物中，发现有效的体外活性与氨基取代有关。但是，这种活性取决于特定的结构特征，而不取决于还原潜力。活性最高的化合物仅显示出较差的体内活性。
