Herein, we report the syntheses and structure-activity relationships of Santamarine, Douglanine, dihydrosantamarine, 1-oxygenated and 3-oxygenated eudesman-12,6α-lactones. The anti-inflammatory and anti-cancer activities were measured by the inhibition on induction of intercellular adhesion molecule (ICAM-1), killing function of cytotoxic T lymphocytes (CTLs), and cytotoxic activities to cell lines
在此,我们报告了 Santamarine、Douglanine、dihydrosantamarine、1-氧化和 3-氧化 eudesman-12,6 α -内酯的合成和构效关系。通过抑制细胞间粘附分子(ICAM-1)的诱导,细胞毒性T淋巴细胞(CTL)的杀伤功能和对细胞系(VA-13,HepG-2)的细胞毒活性来测量抗炎和抗癌活性, 和 WI-38), 分别。具有 1-oxo-2-en 部分的α -Methylene- γ -lactones 13对 ICAM-1 (IC 50 12.8 μM)、CTLs (IC 50 11.0 μM) 和 VA-13 细胞系的杀伤功能具有显着抑制作用(IC 50 2.84 μM), 21α-溴酮部分对 VA-13 有显着抑制作用(IC 50 1.85 μM)。13个((细胞活力)/(ICAM-1 的抑制活性)= 6.0 倍,WI-38/VA-13 = 1
