Sulfates and glucuronides of 2, 4-dinitrobenzyl alcohol 1a and 2, 6-dinitrobenzyl alcohol 1b, which are major or putative metabolites of 2, 4-dinitrotoluene (2, 4-DNT) and 2, 6-dinitrotoluene (2, 6-DNT), were synthesized from 1a and 1b by reaction with pyridinium sulfonate and methyl (2, 3, 4-tri-O-acetyl-α-D-glucopyranosyl)uronate bromide 3, respectively, as their pyridinium salts (2a, 2b) and potassium salts (6a, 6b). These conjugates are important for the study of the carcinogenicity of 2, 4-DNT and 2, 6-DNT.
2, 4-二硝基苄醇1a和2, 6-二硝基苄醇1b的主要或假定代谢物,即它们的硫酸酯和葡糖苷酸,是通过1a和1b分别与吡啶硫酸酯和甲基(2, 3, 4-三-O-乙酰基-α-D-吡喃葡萄糖苷酸)溴化物3反应合成的,形成它们的吡啶盐(2a, 2b)和钾盐(6a, 6b)。这些结合物对于研究2, 4-二硝基甲苯(2, 4-DNT)和2, 6-二硝基甲苯(2, 6-DNT)的致癌性至关重要。
