Tuberiferin, 6-epi-tuberifelin, dehydrobrachylaenolide and two series of eudesmanolides, eudesmane-12,6 α-lactones and eudesmane-12,6β-lactones, were synthesized for the studies of the structure–activity relationships to explore novel anti-inflammatory, anti-cancer and crop disease prevention agents. The anti-inflammatory activities were tested by the inhibitory on the induction of inter-cellular adhesion
合成了tuberiferin、6- epi -tuberifelin、dehydrobrachylaenolide 和两个系列eudesmanoides,eudesmane-12,6 α-内酯和eudesmane-12,6β-内酯,用于研究结构-活性关系以探索新型抗炎、抗癌剂和作物病害预防剂。通过抑制细胞间粘附分子(ICAM-1)的诱导,白细胞向小鼠炎症气囊的渗透,细胞毒性T淋巴细胞(CTL)的杀伤功能,产生IL-1; 抗癌活性建立在对六种细胞系(P388、CCRF-CEM、VA-13、HepG2、QG-56和WI-38)的细胞毒活性上。结果表明,脱氢短链烯内酯(一种外切-endo 交叉共轭二烯酮和 α-亚甲基γ-内酯)是抑制 ICAM-1 (IC 50 3.0 μM) 和细胞系 VA-13 (IC 50 0.45 μM)的最有效化合物;具有 α-溴-酮部分的化合物20在体内对白细胞渗透到
