According to the properties of substituted thiourea derivatives,4 symmetric and 12 unsymmetric thiourea compounds were synthesized by reaction of alkyl amine or substituted aniline with carbon bisulfide or some isothiocyanates .

针对不同活性的取代硫脲，采用脂肪胺或取代苯胺与二硫化碳或不同种类的异硫氰酸酯反应，合成了4种对称的和12种非对称的硫脲衍生物。

We found, on the one hand, urea can cause cytochrome cboth on the electrode surface and in the solution to be denatured and then the denaturedprotein lends to move the formal potential of the native protein in the bulk solution to amore negative value; and on the other hand, urea can also cause the formal potential ofnative protein in the bulk solution to shift positively with decreasing the degrees ofdissociation of electrolytes and polarity of the urea-water solvent.

我们发现脲能引起电极表面和溶液中的细胞色素C的变性，变性蛋白质能导致本体溶液中天然蛋白质的标准式电位的负移；另一方面，通过降低电解质的离解度和脲-水溶剂的极性，脲能使本体溶液中天然蛋白质的标准式电位正移。
