物理化學(xué)性質(zhì)
制備方法
用氫氧化鈉溶液、硫黃配制多硫化鈉，用多硫化鈉作還原劑，在乙醇介質(zhì)中將對硝基甲苯氧化還原，生成對氨基苯甲醛。后者在鹽酸存在下與苯胺縮合，生成三（4-氨基苯基）甲烷鹽酸鹽，經(jīng)燒堿中和、蒸出苯胺，再經(jīng)鹽酸酸化、活性炭脫色、液堿中和、干燥、粉碎，得成品。合成反應(yīng)式如下
常見問題列表
4,4’,4"-三氨基三苯甲烷是丙型肝炎病毒解旋酶的抑制劑。4,4’,4"-三氨基三苯甲烷具有致癌活性，增加了動物直腸內(nèi)皮系統(tǒng)腫瘤的發(fā)生率。
HCV helicase
Tris(4-aminophenyl)methane (Compound 8) shows weak HCV helicase inhibition (30% inhibition at 100 μM). To preserve RNA in a biological sample for analysis, the sample is incubated with an RNA preservative capable of precipitating RNA in an aqueous solution, such as a triphenylmethane dye (e.g., methyl green, crystal violet, pararosaniline, or Tris(4-aminophenyl)methane), cresyl violet, or cobalt ions. RNA preservation may be used in an immunostaining assay and other histochemical methods.
