A series of sixteen A-ring modified (2,3-indolo-, 2-benzylidene) oleanonic acid derivatives, holding some cyclic amines, linear polyamines and benzylaminocarboxamides at C28, has been synthesized and screened for antiviral activity against influenza A/PuertoRico/8/34 (H1N1) and Dengue virus serotypes of DENV-1, -2, -3, -4. It was found that 28-homopiperazine and 3--phthalyl amides of oleanonic acid demonstrated high potency with selectivity index SI 27 (IC 21 μM) and 42 (IC 12 μM). Oleanonic acid aminoethylpiperazine amide and C-azepano-erythrodiol appeared to be the most effective compounds against DENV-1 (ICs 67 and 107 μM) and -2 (ICs 86 and 68 μM correspondingly) serotypes.
已合成并筛选了一系列十六个 A 环修饰(2,3-吲哚基,2-亚苄基)齐墩果酸衍生物,其 C28 位上含有一些环状胺、线性多胺和苄氨基甲酰胺,以对抗流感 A/PuertoRico/8/34(H1N1)和登革热病毒血清型 DENV-1、-2、-3、-4。发现 28-高哌嗪和 3--邻苯二甲酰基酰胺具有较高的活性,选择性指数 SI 分别为 27(IC 21 μM)和 42(IC 12 μM)。齐墩果酸氨基乙基哌嗪酰胺和 C-氮杂-赤式二醇似乎是针对 DENV-1(ICs 67 和 107 μM)和 -2(ICs 86 和 68 μM)血清型最有效的化合物。
