3. CANCER:- Cancer is characterized by rapid and uncontrolled formation of abnormal cells which may mass together to form a growth or tumor, or proliferate throughout the body, initiating abnormal growth at other sites. ANTI-CANCER DRUGS:- The Drugs that are used in inhibiting the abnormal cell growth or killing the cancer cells. 3 INTRODUCTION:

4. WORLD WIDE DEATH RATE OF CANCER 4 14.1 million new cancer case. 8.2 million cancer deaths and 32.6 million people living with cancer 57% new cancer cases, 65% cancer deaths . 7 lakh indians died of cancer last year: who 25% higher in men than in women, mortality: 15% higher in more developed in men, and 8% higher in women.

8. Plant Species Currently Used in Clinical Cancer Treatment 8 1. Campotheca acuminata L. (Nyssaceae; Chinese Happy , Tree—Xi Shu , Cancer Tree) Campotheca acuminata is a native tree of Southern China and Tibet. MOA : It contains the quinoline alkaloid camptothecin (CPT), which inhibits topoisomerase I and therefore DNA replication USE : Traditionally used in China to treat different kind of cancers, especially cancers of the stomach and liver, and breast cancer, colon cancers, malignant melanoma, small-cell lung cancer and leukemia.

9. 2. Podophyllum peltatum L. ( Berberidaceae ) 9 B. Source: Podophyllum hexandrum Family: Berberidaceae Part used: dried rhizomes & roots Chemical constituent: Podophyllotoxin Etoposide Teniposide Uses: Used in treatment of small cell carcinoma of lung, prostrate and testicular carcinomas

10. MOA of Podophyllum 10 Acts by inhibiting topoisomerase II These drugs are most active in late S and early G2 phase

11. Vinca rosea Linn. (Periwinkle) 11 B. source: Catharanthus roseus Family: Apocynaceae Part used: Dried whole plant Active ingredients Ajmalicine , vindoline , catharanthine . alkaloids: vinblastine (VBL), vincristine (VCR) and leurosidine .

12. MODE OF ACTION OF VINCA 12 These drugs block the formation of mitotic spindle by preventing the assembly of tubulin dimers into microtubules. They act primarily on the M phase of cancer cell cycle.

13. USES OF VINCA 13 Traditional uses include soothing and healing of inflammatory ailments of the skin, as well as eye irritations and infections. In modern medicine, the plant extract has been used for the treatment of diabetes, high blood pressure, asthma, constipation, and menstrual problems Leukemia, skin cancer, lymphoma, acute leukemia, breast cancer, lung cancer, brain tumors, Wilms tumors, multiple myeloma, neuroblastoma .

14. TAXANE 14 B. source : Taxus brevifolia Family: Taxaceae Part used : Stem bark Uses: Ovarian cancer Lung carcinoma Gastric & Cervical cancers Prostate & colon cancer Chemical constituent: Taxol Paclitaxel Docetaxal

15. MOA of Taxanes 15

16. CURCUMIN SYNONIM: Haladi BIOLOGICAL SOURSE: Curcuma longa. FAMILY : Zingiberaceae CHEMICAL CONSTITUENT: curcumin Demethoxycurcumin bisdemethoxycurcumin USE: anticancer antiinflamatory, Woundhealing so many use. 16

17. Anticancer activity Mediated partly through inhibition of protein tyrosine kinase and the apoptotic effect may partly be mediated through inhibition of protein tyrosine kinase , Curcumin induces apoptotic cell death by DNA-damage in human cancer cell Suppression of cyclooxygenase-2 (COX-2) and lipooxygenase expression, which blocks production of prostaglandins and leukotrienes Suppression of cyclin D1 which is a proto-oncogene overexpressed in many cancers (e.g., breast, esophagus, lung, liver, head and neck, colon, and prostate Suppression of various inflammatory cytokines, including tumor necrosis factor, angiogenesis, a crucial step in the growth and metastasis of many cancers 9

18. Curcumin also suppresses tumour growth through Nitric oxide (NO) and its derivatives play a major role in tumour promotion. Curcumin inhibit COX-2 production by suppression of NFkB activation. Curcumin also increases NO production in Natural Killer (NR) cells after prolonged treatment, culminating in a stronger tumouricidal effect. curcumin , to suppress the growth of a variety of tumor cells. 10

23. Conclusion 23 Over the years, a number of approaches have been developed for clinical use and a number of anticancer drugs have come out of these as a result, good number of anticancer agents have been developed from plants or their derived agents, development of a safe, economic and site-specific anticancer drug is still a challenge. Perhaps, scientists will have to look towards nature for another diverse molecule with a novel mode of action to Treat this dreadful Disease(cancer).
