New quaternary alkylammonium conjugates of steroids were obtained by two step reaction of sterols (ergosterol, cholesterol, dihydrocholesterol) with bromoacetic acid bromide, followed by bimolecular nucleophilic substitution with a long chain tertiary alkylamine. The structures of products were confirmed by spectral (1H-NMR, 13C-NMR, and FT-IR) analysis, mass spectrometry and PM5 semiempirical methods. The pharmacotherapeutic potential of synthesized compounds has been estimated on the basis of Prediction of Activity Spectra for Substances (PASS).
新型季铵盐甾体化合物是通过甾醇(麦角甾醇、胆固醇、二氢胆固醇)与溴乙酸溴反应,再与长链叔胺双分子亲核取代两步反应得到的。通过光谱(1H-NMR、13C-NMR 和 FT-IR)分析、质谱和 PM5 半经验方法确认了产物的结构。根据预测的物质活性谱(PASS)估计了合成化合物的治疗潜力。
