Wedelolactone stimulates ER genomic and non-genomic signalling pathways; it can significantly inhibit the activation of LX-2 cells, the underlying mechanisms of which included inducing Bcl-2 family involved apoptosis, up-regulating phosphorylated status of ERK and JNK expressions, and inhibiting NF-κB mediated activity.

Genistein, the major phytoestrogen in soy, is linked to diminished female reproductive performance and to cancer chemoprevention and decreased adipose deposition; genistein-induces hypermethylation persisted into adulthood, decreases ectopic Agouti expression and protecting offspring from obesity, suggests that in utero dietary genistein affects gene expression and alters susceptibility to obesity in adulthood by permanently altering the epigenome.

Catechin gallate is a minor constituent in green tea catechins, it inhibits the activity of COX-1 and COX-2 enzymes. Catechin gallate (IC50=53 microM) shows cytotoxicity against the colorectal adenocarcinoma cell line HCT116, it also exhibits strong anti-proliferative and anti-inflammatory activities on pancreatic ductal adenocarcinoma (PDAC) cells. Catechin 3-gallate is a good inhibitor of maltase, with IC50 values of 62 uM, it inhibits both α-glucosidases and rabbit glycogen phosphorylase (GP) in vitro and in cell culture, would contribute to the protection or improvement of type 2 diabetes.

Chrysosplenetin is a metabolic inhibitor of artemisinin, it has strong activity in vitro against EV71 with low cytotoxicity. Co-administration of artemisinin(ART) with chrysosplenetin(CHR) in ratio of 1:2 achieved a synergic anti-malarial effect partly because of the noncompetitive or uncompetitive inhibition of CHR of drug-metabolism enzymes, especially CYP3A which is closely related to the auto-induction of ART.

Rutin is a natural antioxidant, all doses can diminish reactive oxygen species and high doses (10-100 microM) decrease malondialdehyde concentration; induce favorable changes in the antioxidant defense system of cultured HepG2 that prevent or delay conditions which favor cellular oxidative stress.

Isoliensinine has anti-cancer, anti-fibrosis, anti-proliferative, antioxidant, and anti-inflammatory activities, it inhibited TNF-alpha and TGF-beta 1; decreased the overexpression of growth factors Platelet-derived growth factor (PDGF)-beta, basic fibroblast growth factor (bFGF), proto-oncogene c-fos, c-myc and hsp70; and activated ROS and p38 MAPK/JNK .

Cratoxylone exhibits potent activity in vitro against Plasmodium falciparum chloroquine-resistant strain W2, with the IC₅₀ value belows 3 uM.

Costunolide, a sesquiterpene lactone isolated from the root of Saussurea lappa Clarke, has a variety of biological activities, including anti-carcinogenic and anti-fungal activities,

Naringin Dihydrochalcone is an artificial sweetener derived from naringin. Naringin is a major flavanone glycoside obtained from tomatoes, grapefruits, and many other citrus fruits. Naringin exhibits biological properties such as antioxidant, anti-inflammatory, and antiapoptotic activities. Naringin suppresses NF-κB signaling pathway.

Narirutin has anti-inflammatory effect in a murine model of allergic eosinophilic airway inflammation, the mechanism is likely to be associated with a reduction in the OVA-induced increases of IL-4 and IgE, suggests that narirutin may be an effective new tool in the treatment of bronchial asthma.

Caftaric acid is an inhibitor of the protein-protein interactions mediated by the Src-family kinases, which has anti-mutagenicity. Caftaric acid is the major dietary polyphenol present in various foods, it before methamphetamine injections can prevent liver toxicity and oxidative stress.

Alisol B 23-acetate, a partial non-competitive inhibitor of P-gp, it may be a potential MDR reversal agent. Alisol B 23-acetate produces protective effects against ANIT-induced hepatotoxity and cholestasis, due to FXR-mediated gene regulation; it obviously inhibits proliferation of the three ovarian cancer cell lines, possesses anti-proliferation, anti-migration and anti-invasion activities as a single agent on ovarian cancer cells.
