摘要

采用cu催化的Mannich反应合成了C（28）位含有丙炔胺取代基的新型a -二齐墩果酸和a -二桦木酸衍生物。在MDCK细胞培养中评价化合物对甲型流感/波多黎各/8/34 （H1N1）病毒的抗病毒性能。结果表明，在a -二齐墩果酸的曼尼希碱中，含哌嗪部分的衍生物活性最高（IC50 = 5µmol L−1,SI >100）。在a -二白桦酸中，n -甲基哌嗪（IC50 = 1 μ mol L−1,SI >25）和啉（IC50 = 3 μ mol L−1,SI = 42）的引入产生了积极的影响。

Antiviral activity of Mannich bases linked to A-secotriterpenoids at the C(28) position

Novel derivatives of A-secooleanolic and A-secobetulinic acids containing a propargylamine substituent at the C(28) position were synthesized via the Cu-catalyzed Mannich reaction. Antiviral properties of the compounds were evaluated on MDCK cell culture against influenza A/Puerto Rico/8/34 (H1N1) virus. It was demonstrated that among the Mannich bases of A-secooleanolic acid, the derivative containing the piperazine moiety exhibited the highest activity (IC₅₀ = 5 µmol L⁻¹ and SI >100). In the case of A-secobetulinic acid, a positive effect was caused by the introduction of N-methylpiperazine (IC₅₀ = 1 µmol L⁻¹ and SI >25) and morpholine (IC₅₀ = 3 µmol L⁻¹ and SI = 42) moieties.
