The anticancer potency of the ethanolic extract of Terminalia arjuna on N-nitrosodiethylamine (DEN) induced hepatocellular carcinoma in Wistar albino rats was studied. Single intraperitoneal injection of DEN was administrated to induce liver cancer. After two weeks, phenobarbital (PB) was given orally for fourteen weeks to promote the cancer. The cancer bearing animals treated with ethanolic extract of T.arjuna (400 mg/kg body weight) for 28 days. Nucleic acids such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) were estimated in liver and kidney of control and experimental animals. Certain marker enzymes viz, alanine aminotransaminase (ALT), aspartate aminotransaminase (AST), acid phosphatase (ACP), alkaline phosphatase (ALP), 5'-nucleotidase (5'ND) and lactate dehydrogenase (LDH) were assayed in serum, liver and kidney of control and experimental animals. The levels of DNA and RNA were significantly increased in cancer bearing animals. The activities of ALT, AST, ACP, ALP, 5'ND, and LDH were significantly (P < 0.001) increased in serum of cancer bearing animals. On the other hand, the levels of ALT, AST were decreased (P < 0.001) and ACP, ALP, 5'ND, and LDH were significantly increased (P < 0.001) in liver and kidney. These changes were reversed to near normal in drug treated animals. These observations suggest that the ethanolic extract of T.arjuna possess anticancer activity.

Colon cancer is considered as the precarious forms of cancer in many developed countries, with few to no symptoms; the tumor is often diagnosed in the later stages of cancer. Monoterpenes are a major part of plant essential oils found largely in fruits, vegetables and herbs. The cellular and molecular activities show therapeutic progression that may reduce the risk of developing cancer by modulating the factors responsible for colon carcinogenesis. Colon cancer was induced with DMH with a dose of (20 mg/Kg/body weight) for 15 weeks by subcutaneous injection once in a week. Myrtenal treatment was started with (230 mg/Kg/body weight) by intragastric administration, one week prior to DMH induction and continued till the experimental period of 30 weeks. The Invivo results exhibit the elevated antioxidant and lipid peroxidation levels in DMH treated animals. The Histopathological analysis of colon tissues well supported the biochemical alterations and inevitably proves the protective role of Myrtenal. Treatment with myrtenal to cancer bearing animals resulted in a remarkable increase in the inherent antioxidants and excellent modulation in the morphological and physiological nature of the colon tissue. It is thus concluded that myrtenal exhibits excellent free radical scavenging activity and anticancer activity through the suppression of colon carcinoma in Wistar albino rats.

Development of drugs from natural products has been undergoing a gradual evoluation. Many plant derived compounds have excellent therapeutic potential against various human ailments. They are important sources especially for anticancer agents. A number of promising new agents are in clinical development based on their selective molecular targets in the field of oncology. D-pinitol is a naturally occurring compound derived from soy which has significant pharmacological activitites. Therefore we selected D-pinitol in order to evaluate apoptotic potential in the MCF-7 cell line. Human breast cancer cells were treated with different concentrations of D-pinitol and cytotoxicity was measured by MTT and LDH assays. The mechanism of apoptosis was studied with reference to expression of p53, Bcl-2, Bax and NF-kB proteins. The results revealed that D-pinitol significantly inhibited the proliferation of MCF-7 cells in a concentration-dependent manner, while upregulating the expression of p53, Bax and down regulating Bcl-2 and NF-kB. Thus the results obtained in this study clearly vindicated that D-pinitol induces apotosis in MCF-7 cells through regulation of proteins of pro- and anti-apoptotic cascades.
