Rubiadin (1,3-Dihydroxy-2-Methylanthracene-9,10-Dione) possesses potent antioxidant property, it can prevent lipid peroxidation induced by FeSO4 and t-butylhydroperoxide (t-BHP) in a dose dependent manner.

L-Chicoric Acid (trans-Caffeoyltartaric acid) has been shown to inhibit hyaluronidase and HIV-1 integrase, and to possess phagoeytosis stimulatory activity in vitro and in vivo and antiviral acitivy. L-Chicoric acid may reduce acute alcohol-induced steatosis in mice through interfering with the induction of iNOS and iNOS-dependent signaling cascades in the liver. 3. L-Chicoric acid inhibited cell viability and induced apoptosis in 3T3-L1 preadipocytes which was characterized by chromatin condensation and poly ADP-ribose-polymerase (PARP) cleavage.

Erucin （1-isothiocyanato-4-methylsulfanylbutane） is a dietary isothiocyanate produced by enzymatic hydrolysis of glucoErucin with potential cancer preventive effects, involved in apoptosis and cell cycle blockade through PARP-1 cleavage, p53 and p21，Cyp450, quinone reductase (QR), glutatione transferase (GST) and other pathways.

Myristicin (Myristicine) is a natural product found in spices and umbelliferous plants. Myristicin has anti-cholinergic, Antibacterial, and hepatoprotective effects, it also has anti-inflammatory properties related with its inhibition of NO, cytokines,chemokines, and growth factors in dsRNA-stimulated macrophages via the calcium pathway. Myristicin can induce Apoptosis as characterised by alterations in the mitochondrial membrane potential, cytochrome c release, Caspase-3 activation, PARP-cleavage and DNA fragmentation.

Lucidenic acid B (Lucidenicacid B), a natural compound extracted from Ganoderma lucidum, induces activation of caspase-9 and caspase-3 and cleavage of PARP, which can induce apoptosis in human leukemia cells through mitochondrial mediation. Lucidenic acid B inhibits PMA-induced invasion of human hepatocellular carcinoma cells by inactivating the MAPK ERK signaling pathway and decreasing the binding activity of NF-kappaB and AP-1. Lucidenic acid B had no effect on cell cycle and necrotic cells.

ExcisaninA may be a potent inhibitor of AKT signaling pathway in tumor cells, it can inhibit invasion by suppressing MMP-2 and MMP-9 expression, it may be a potential anti-metastatic chemotherapeutic agent for the treatment of breast cancer. Excisanin A shows comparable inhibitory effects on the LPS-induced production of NO and PGE2, and activation of NF-kappaB without affecting cell viability.Excisanin A induces apoptosis in colon cancer cell line SW620 as determined by Annexin V staining, the cleavage of caspase-3 and the proteolytic degradation of poly (ADP-ribose) polymerase (PARP).
