Yatein inhibits herpes simplex virus type 1 replication by interruption the immediate-early gene expression. Yatein is a lignan isolated from A. chilensis. It also has antiproliferative activity.
β-Cembrenediol (β-CBT) is a natural product from tobacco plants that is found in cigarette smoke condensate. β-CBT inhibits induction of the early antigen of Epstein-Barr virus (EA-EBV) by 12-O-tetradecanoylphorbol-13-acetate (TPA) in vitro (IC50 = 21.9 μM). It inhibits tumor promoting effects of TPA on 7,12-demethylbenz[a]anthracene-induced papilloma formation in vivo. β-CBT is also released into soil by flue-cured tobacco plants and exerts autotoxicity as well as phytotoxic activity against L. sativa seedlings.
9,13β-Epidioxy-8(14)-abieten-18-oic acid has anti-inflammatory activities, it exhibits moderate activities on NO levels in LPS-stimulated murine microglia BV2 cells, with IC50 values of 57.3 ± 0.2 uM. It is also a potential antitumor-promoting diterpenoid, it shows potent inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by the tumor promoter 12-O-tetradecanoylphorbol 13-acetate. 9 α ,13 β -Epidioxyabeit-8(14)en-18-oic acid may contribute to the growth inhibitory effect of the pine needles and may play an important role in the allelopathy of red pine.
11-Oxomogroside II A1(化合物 7)是一种从罗汉果乙醇提取物中分离的氧化葫芦苷,对12-O-十四烷酰基激素-13-乙酸酯(TPA)诱导的Epstein-Barr病毒(EBV)早期抗原(EBV-EA)活化具有抑制效果,并对一氧化氮(NO)供体(+/-)-(E)-甲基-2-[(E)羟基亚氨基]-5-硝基-6-甲氧基-3-己酰胺(NOR 1)的活化也展示出轻微的抑制作用。
