from NPs, a series of novel merrillianone/cycloparviforalone based esters 2a–i, 3a–g and 3i–q were prepared and their structures were characterized by 1H NMR, 13C NMR and IR spectral analyses. Furthermore, the spatial structure of compound 2h was unambiguously confirmed by X-ray crystallography. The neurite outgrowth-promoting activity results indicated that most of the target derivatives exhibited
天然产物(NPs)是开发新药的重要来源。Merrillianone 和 cycloparvifloralone是两种天然倍半萜化合物,从Illicium henryi Diels的根、茎和果实中分离出来。为了继续从 NPs 中发现更有效的神经营养化合物,我们制备了一系列新的基于 merrillianone/cycloparviforalone 的酯2a - i、3a - g和3i - q,并通过1 H NMR、13 C NMR 和红外光谱分析。此外,化合物2h的空间结构X 射线晶体学明确证实。神经突生长促进活性结果表明,大多数目标衍生物表现出比merrillianone和cycloparviforalone更有效的神经突生长促进活性。在所有目标衍生物中,化合物2a、3a和3b的神经突生长促进活性分别比它们的前体美瑞林酮和环小霉素的活性强约 2 倍。此外,化合物2a和3a对正常 GES-1
