New dimeric quaternary alkylammonium conjugates of sterols were obtained by two step reactions of ergosterol, cholesterol and cholestanol with bromoacetic acid bromide, followed by bimolecular nucleophilic substitution with N, N, N', N'-tetramethyl-1,3-propanediamine, N, N, N', N'', N''-pentamethyldiethylenetriamine and 3,3'-iminobis-(N, N-dimethylpropylamine). The product structures were confirmed
通过麦角甾醇、胆固醇和胆甾醇与溴乙酸溴化物的两步反应,然后用 N, N, N', N'-四甲基-1,3-丙二胺、N、 N, N', N", N" - 五甲基二亚乙基三胺和 3,3'-亚氨基双-(N, N-二甲基丙胺)。产物结构通过光谱( 1 H-NMR、 13 C-NMR、 FT-IR)分析、质谱(ESI-MS)和PM5半经验方法确定。此外,还根据物质活性谱预测 (PASS) 对合成化合物进行了计算机模拟研究。
