possess anticancer activity, however, studies on its potential anticancer activity remain limited and few. In this study, we further investigated the anticancer potential of clusianone by initially isolating clusianone from Garcinia parvifolia leaves and then using it to synthesise a total of 8 analogues, of which 5 are novel and being reported for the first time. Clusianone and its analogues’ reactivity
Clusianone 是一种天然产物,已被证明具有抗癌活性,然而,对其潜在抗癌活性的研究仍然有限且很少。在本研究中,我们进一步研究了clusianone的抗癌潜力,首先从Garcinia parvifolia叶中分离出clusianone,然后用它合成了总共8个类似物,其中5个是新颖的且首次报道。对 Clusianone 及其类似物的反应性和化学性质进行了深入研究,同时获得并讨论了甲基化 Clusianone(化合物 1)的晶体结构。利用1的晶体结构进行Hirshfeld表面分析,发现H…H相互作用对晶体堆积贡献最大。此外,DFT计算表明,计算出的1优化结构的理论参数与实验X射线衍射测量结果吻合良好。通过 MTT 测定进一步针对 A549(肺)和 HK1(鼻咽)癌细胞筛选以良好产率获得的类似物。结果表明,向 clusianone 中引入亚胺 (C=N) 基团会产生生物活性化合物,其中甲胺衍生物(化合物
