Notoginsenoside R1(NR1) is the main ingredient with cardiovascular activity in Panax notoginseng, which has some neuronal protective, antihypertensive,antioxidant, anti-inflammatory, antiapoptotic, and immune-stimulatory activities. NR1 can counteract endotoxin-induced activation of endothelial cells in vitro and endotoxin-induced lethality in mice in vivo. NR1 inhibits TNF-α-induced PAI-1 overexpression via extracellular signal-related kinases (ERK1/2) and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (PKB) signaling pathways, it attenuates amyloid-β-induced damage in neurons by inhibiting reactive oxygen species and modulating MAPK activation.

Germacrone, a natural product isolated from Rhizoma curcuma, can inhibit the proliferation of breast cancer cell lines by inducing cell cycle arrest and apoptosis through mitochondria-mediated caspase pathway.

Wogonoside has anticoagulant, anti-inflammatory, anti-angiogenic and anticancer effects, it may exert its anti-inflammatory effect via dual inhibition of NF-κB and NLRP3 inflammasome. Wogonoside induced autophagy through the MAPK-mTOR pathway, it inhibited LTB 4 production at the concentration of 100 uM.

Sophoridine has anti-inflammatory, anti-cancer and anti-arrhythmia, and affects the immune and central nervous systems. Early and short-time applying sophoridine has neuroprotective effect min permanent middle cerebral artery occlusion (pMCAO) rat brain by down-regulating TRAF6 and up-regulating p-ERK1/2 expression, ameliorating brain infaction and edema. Sophoridine also possesses antiviral activities against Coxsackievirus B3, by regulating cytokine expression, may represent a potential therapeutic agent for viral myocarditis.

Isoescin IB is a natural product from Aesculus hippocastanum L.

Aristolochic acid II (AAII), one of the major components of the carcinogenic plant extract aristolochic acid, is known to be mutagenic and to form DNA adducts in vitro and in vivo,

SaikosaponinD (SSd) is a major triterpenoid saponin derivative from Radix bupleuri, which has been long used in Chinese traditional medicine for treatment of various inflammation-related diseases; it shows potent anti-inflammatory activity through inhibitory effects on NF-κB activation and thereby on iNOS, COX-2 and pro-inflammatory cytokines.
