Mini Review on Some African Plants with Anti-Cancer Properties

JOURNAL OF RESEARCH AND REVIEW IN SCIENCE

Every year, cancer takes the life of millions of people. Indeed, medicinal plants have long been investigated by scientists for their anti-cancer properties. Herbal plants have recently attracted worldwide attention of researchers for their possible use in the management of diseases such as diabetes, cardiovascular diseases, cancer, and respiratory diseases. Most of the conventional cancer treatment options have produced unsatisfactory results for some types of cancers, and in most instances, the side effects are severe, leading to a shift in the focus of treatment towards alternative medicines. Plant-derived compounds have been a vital source of most of the known clinically useful anti-cancer agents. These include vinblastine, vincristine, the camptothecin derivatives, topotecan and irinotecan, etoposide, derived from epipodophyllotoxin, and paclitaxel (taxol®), taxanes, homoharringtonine and elliptinium. Many promising new agents are in clinical development based on selective acti...

Journal of Medicinal Plants Research In vitro anticancer activity of some plants used in Moroccan traditional medicine

Over time, cancer remains a world public health problem. The use of traditional medicine as alternative treatments of cancer was recognized in 1950s by the US National Cancer Institute (NCI) under the leadership of the late Dr. Jonathan Hartwell. In this context, we are interested to search for bioactive natural substances for cancer therapy used in Moroccan traditional medicine. Based on ethnopharmacological study, we selected four plants with an important therapy against cancer in Moroccan traditional medicine; these are Aristolochia longa (L), Citrullus colocynthis (L), Piper cubeba (L) and Delphinium Staphisagria (L). In the pharmacological study, we evaluated the antiproliferative activity of selected Moroccan plants on five different cancer cell lines namely MCF7, HT29, N2A, H5-6 and VCREMS using 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay at a dose of 500 µg/ml; lyophilized extracts after 24 h of treatment showed that two plants possess significant cytotoxic activity against cancer cell lines, such as MCF7, HT29, N2A, H5-6 and VCREMS. P. cubeba (L) extract showed the inhibition of 98.64 and 91.59% against MCF7 lines and HT29 cell lines, and for C. colocynthis (L), 91.84 and 85.58%, respectively. C. colocynthis (L) showed a dose-dependent effect on MCF7 and HT29 cell lines with an IC 50 of 22.0 and 32.5 µg/ml, respectively. This cytotoxicity is induced probably by apoptosis.

In vitro Antiproliferative Studies of Selected Medicinal Plants on Cancerous and Normal Cells

European Journal of Medicinal Plants

Globally, approximately 13% of all deaths annually are attributed to cancer. Surgery, radiation and chemotherapy are the current treatment techniques for cancer; however, these methods are expensive, have high failure rates and have been associated with detrimental side effects. Plant derived products could be good candidates in alleviating challenges being experienced with these current methods. This study aimed at evaluating the phytochemistry, antiproliferation potential, and probable mechanism of action of Albizia gummifera, Rhamnus staddo and Senna didymobotrya plant extracts. The 3– (4, 5-dimethylthiazol-2-yl) -2, 5-diphenyltetrazolium (MTT) assay dye was used in the determination of the antiproliferative activity of the extracts. Extracts induction potential of p53 (apoptosis) and VEGF (angiogenesis) genes’ expression was evaluated using Real Time PCR. Phytochemical screening was done as per standard procedures. Several plant extracts exhibited antiproliferative activity agai...

Evaluating medicinal plants for anticancer activity

TheScientificWorldJournal, 2014

Plants have been used for medical purposes since the beginning of human history and are the basis of modern medicine. Most chemotherapeutic drugs for cancer treatment are molecules identified and isolated from plants or their synthetic derivatives. Our hypothesis was that whole plant extracts selected according to ethnobotanical sources of historical use might contain multiple molecules with antitumor activities that could be very effective in killing human cancer cells. This study examined the effects of three whole plant extracts (ethanol extraction) on human tumor cells. The extracts were from Urtica membranacea (Urticaceae), Artemesia monosperma (Asteraceae), and Origanum dayi post (Labiatae). All three plant extracts exhibited dose- and time-dependent killing capabilities in various human derived tumor cell lines and primary cultures established from patients' biopsies. The killing activity was specific toward tumor cells, as the plant extracts had no effect on primary cult...
