The traditional synthetic method of 2 , 5 - dithiol - benzene - 1 , 4 - diamine dihydrochloride ( dtbda ) is characterized by a louger time of reaction , heigher consumption on chemicals and lower yield . but by changing the solvent for synthesis , the reaction time is shortened and the consumption on chemicals is lowered 通过改变合成的溶剂对已报道的合成二巯基苯二胺二盐酸盐方法进行改进，克服了需经很长周期、耗用大量的反应试剂和重结晶溶剂、产率较低的缺点.改进的方法缩短了产物制备时间，减少了原料的成本消耗，效果明显

Thioredoxins , an ubiquitous small proteins with a redox active disulfide bridge in its conserved motif - cp ( g ) pc - , are universally distributed in eucaryote and procaryote and have a molecular mass of approximately 12kda . by its disulfide / dithiol interchange reaction , this protein can transmit the regulatory signals to seleted targets ( enzymes , transcription factors etc ) and plays an important role in many plant physiological processes that includes photosynthesis , dna synthesis , transcription , protein disulfide reduction , protein repair , filamentous phage assembly , cell apoptosis and seeds germinating and so on 该蛋白质中含有保守的- cp ( g ) pc -氨基酸活性基序，该基序中的两个半胱氨酸残基可通过巯基二硫键的转换实现其氧化还原状态的变化和电子氢的传递，对细胞中与氧化还原相关的多种生理过程的调节起重要作用。通过同许多酶类、蛋白类、细胞内活性因子相藕连， trx能对光合作用、 dna复制、基因转录、细胞凋亡和生长、噬菌体组装、蛋白质的还原和修复信号传导等生理过程产生影响和调节。
