One of the most favorable effects of TQ is that it exhibits high cancer specificity and low toxicity to normal cells. TQ has been highly sensitivity to prostate cancer, colon cancer and skin cancer. Many multidrug-resistant variants of human pancreatic adenocarcinoma, uterine sarcoma, and leukemia were found to be sensitive to TQ. 35 and 36 The important anticancer metabolites chemical structures were described in Fig. 2 and Fig. 3. Antioxidants are compounds, enzymes or it may metals (non enzymes) that involved in the system auto oxidation mechanism by preventing the formation of free radicals.37 Oxidative stress and reactive oxygen species (ROS) intermediated to cell damage

Screening Library have been associated with the development of human dangerous diseases such as certain cancers, neurological disorders, atherosclerosis and cardiovascular diseases. At the biochemical mechanism of antioxidants in cellular level cells are expose to oxidative stress http://www.selleckchem.com/products/BI-2536.html which in turn causes the highly affected in anabolic and catabolic pathways including amino acid catabolism, protein oxidation, lipid peroxidation, other cellular inner membrane disruption and DNA damage.38 and 39 Plant derived antioxidant compounds

can activate the cellular signaling networks that stimulate the normal cell division function that are observed in abnormal cells. This includes phosphorylation process leading to the activation of enzyme receptor switch on and off mechanisms, kinase and phosphatase enzymes activities, induce the gene expression level, inflammation and cancer. Oxidative regulation in tumor cells may have a strong wave on the host system to response against malignant deposit. The plant crude or purified compounds have been highly potential activity in cytoprotective and genoprotective effects against oxidative stress and it control the free radical formation in electron transport chain

and other metabolic pathways.40 The proper methods of immunization against tumor understandably have not yet found. But GPX6 the revolution of nanopharmaceutics to synthesize the novel nanodrug carrier and specific site of action has been high effect against malignancy cells.41 and 42 Potentially prove the biosynthesized nanoparticles as good effective drug materials for cancer. Particularly piper longumine and piper longuminine act as capping agent for synthesis of silver nanoparticles and it enhance the cytotoxic effect on Hep-2 cell line. Piper longum plant synthesized nanomaterials have significant cytotoxic effect (94%-500ug/ml) against invasive cells.43 The P53 or TP53 tumor suppressor gene is the most frequently changes gene in cancer. The p53 protein is a transcription factor (TF) involved genome function by regulating cell death mechanisms and progression of cell cycle. Accordingly mutation of p53 is often difficult to treat and diagnosis is poor to identity malignancy.
