Forsythoside B binds to LPS and reduces the biological activity of serum LPS, and inhibits NF-κB activation. Forsythoside B inhibits the inflammatory response and has antioxidant properties. Potent neuroprotective effects with a favorable therapeutic time
Cephaeline was highly active against protected primary CLL cells (relative IC50's 35nM ) and acted by repressing HIF-1α± and disturbing intracellular redox homeostasis.
Halofuginone (RU-19110), the competitive inhibitor of prolyl-tRNA synthetase(Ki=18.3 nM), could also down-regulate Smad3 and blocked TGF-β signaling at 10 ng/ml in the mammal.
Evodiamine (d-Evodiamine) is an alkaloid isolated from the fruit of daylily and has a variety of biological activities including anti-inflammatory, anti-obesity and anti-tumor.
Hydrangenol is a natural product and can be isolated from Hydrangea serrata leaves. Hydrangenol is an antiphotoaging compound with oral activity. Hydrangenol can reduce MMP and inflammatory cytokine expression and increase moisturizing factors and antioxidant genes level, result in preventing wrinkle formation.
Camptothecin (CPT) belongs to the alkaloid group of natural products and is a specific DNA topoisomerase I (Topo I) inhibitor (IC50=679 nM) with specificity. Camptothecin has antitumor activity and induces apoptosis.
Vincosamide is an alkaloid from Psychotria leiocarpa extract, inhibits the acetylcholinesterase (AChE) activity with anti-inflammatory activity. Vincosamide can effect relaxation of the supercoiled pBR322 plasmid DNA in the presence of Cu2+.
1. Cornuside (Comuside) has immunomodulatory activity . 2. Cornuside suppresses expression levels of cytokine-induced proinflammatory and adhesion molecules in the human endothelial cells. 3. Cornuside can treat myocardial I/R and protect the liver from CCl4-induced acute hepatotoxicity, by reducing oxidative stress and suppressing inflammatory responses. 4. Cornuside has anti-inflammatory activity by downregulations of iNOS and COX-2 due to NF-κB inhibition as well as the negative regulation of ERK1/2, p38, and JNK1/2 phosphorylations in RAW 264.7 cells. 5. Cornuside has protective potential against cerebral ischemic injury, may be due to the suppression of intracellular Ca(2+) elevation and caspase-3 activity, and improvements in mitochondrial energy metabolism and antioxidant properties.
Phillyrin (Forsythin) is a novel AMPK activator, has anti-obesity effects in nutritive obesity mice, it can prevent lipid accumulation in HepG2 cells by blocking the expression of SREBP-1c and FAS through LKB1/AMPK activation. Phillyrin(Forsythin) may be a new preventive agent of acute lung injury in the clinical setting, it potentially contributes to the suppression of the activation of MAPK and NF-κB pathways, it also has protective effects on H2O2-induced oxidative stress and apoptosis in PC12 cells.
Forsythiaside A (Forsythiaside) has antimicrobial, anticomplementary, anti-inflammatory and antiendotoxin activities. Forsythiaside A inhibits Infected cells was confirmed by infecting primary chicken embryo kidney cells.
(±)-10-Hydroxycamptothecin (Hydroxy Camptothecine) is an alkaloid isolated from the stem wood of the Chinese tree, Camptotheca acuminata. This compound selectively inhibits the nuclear enzyme DNA topoisomerase, type I. Several semisynthetic analogs of camptothecin have demonstrated antitumor activity.
Cephaeline dihydrochloride is a naturally occurring alkaloid that is a selective CYP2D6 inhibitor with an IC50=121 μM. It has an affinity for and oral activity at the 5-HT4 receptor and is capable of inducing vomiting.
12-Ethyl-9-hydroxycamptothecin (SN38) is the active metabolite of irinotecan, a topoisomerase I inhibitor, with potential anticancer activity for use in the study of colon and rectal cancer.
