isolated from Garcinia Mangostana L. as representative Xanthone's natural products of plant origin, revealed high activity of antitumor, antioxidation and other diverse pharmacological activities. A series of α, γ-Mangostin derivatives LT-1~17 has been synthesized, and confirmed by 1H NMR, 13C NMR, MS(supplement file). Compounds LT-2~17, as novel Xanthone, have been reported for the first time. Their antitumor
α?-Mangostin和?-Mangostin主要从藤黄(Garcinia Mangostana L.)中分离出来,作为代表Xanthone的植物来源天然产物,具有很高的抗肿瘤,抗氧化和其他多种药理活性。合成了一系列α,γ,Mangostin衍生物LT-1〜17,并通过1 H NMR,13 C NMR,MS(补充文件)进行了确认。化合物LT-2〜17作为新型的黄酮,已被首次报道。已经通过MTT方法在细胞系:A549,K562,CNE,KB-3-1,MCF-7和HepG2中研究了它们的抗肿瘤活性。许多化合物显示出有效的抗肿瘤活性,在某些情况下甚至比Mangostins更高(更有效)。具有IC 50的化合物3A549细胞系中的1.73 µM值是两倍,比ADM(阿霉素)和α?,γ?-Mangostin活性更高,并且具有最强的抗肿瘤活性(IC 50 = 2.15 µM)。所有合成衍生物中的MCF
