New quaternary alkylammonium conjugates of steroids were obtained by two step reaction
of methyl esters of bile acids with bromoacetic acid bromide, followed by bimolecular nucleophilic
substitution with a long chain tertiary alkylamine. The structures of products were conrmed by spectroscopic
(1H-NMR, 13C-NMR, and FT-IR) analysis, mass spectrometry (ESI-MS) as well as PM5
semiempirical methods. The biological activity of the synthesized compounds has been estimated on
the basis of Prediction of Activity Spectra for Substances (PASS).
通过两步反应合成了新的甾体四级烷基
铵偶联物:先用
胆酸甲酯与
溴乙酰溴反应,随后与长链叔烷基胺进行双分子亲核取代。产物结构通过光谱学(1H-NMR、13C-NMR 和 FT-IR)分析、质谱法(ESI-MS)以及 PM5 半经验方法得到确认。合成化合物的
生物活性基于物质活性谱预测(PASS)进行了评估。
