Extracts of several Southern African plants which have been used in folk remedies have been prepared, and the extracts were tested in a variety of experimental tumour test-systems. Raphionacme hirsuta and Cheilanthes contracta have been used in African anticancer medicines. Extracts of these plants
Of 49 compounds known to have antitumor properties, 6 were found to have significant activity against Trypanosoma rhodesiense infections in mice. Activity against the African trypanosomes has not been reported previously for any of these six compounds. In order of decreasing activity these compounds
OBJECTIVE
The purpose of the present study is to evaluate South African plants for their anticancer activity.
METHODS
Plant species were collected throughout South Africa and voucher specimens were deposited and identified at the South African National Biodiversity Institute. Plant extracts were
OBJECTIVE
The purpose of this review is to examine prostate cancer racial disparities specific to the African-American population.
RESULTS
African-American men are more likely to be diagnosed with prostate cancer, present at an earlier age; are more likely to have locally advanced or metastatic
Naturally occurring anticancer compounds represent about half of the chemotherapeutic drugs which have been put in the market against cancer until date. Computer-based or in silico virtual screening methods are often used in lead/hit discovery protocols. In this study, the "drug-likeness" of ~400
African trypanosomiasis continues to pose a challenge for the development of new chemotherapy. Type II topoisomerases, essential enzymes in nucleic acid metabolism, have proven highly suitable as targets for antibacterial and antitumor therapy. Well-characterized topoisomerase II inhibitors affect
African trypanosomiasis (sleeping sickness), caused by protozoan Trypanosoma brucei species, is a debilitating disease that is lethal if untreated. Available drugs are antiquated, toxic, and compromised by emerging resistance. The indenoisoquinolines are a class of noncamptothecin topoisomerase IB

Dichloromethane and 90% methanol extracts of 42 South African plants were screened for mutagenicity and antimutagenicity using the Salmonella/microsome mutagenicity assay (Ames) against Salmonella typhimurium TA98 and TA100 bacterial strains in the presence and absence of metabolic activator S9. The
African-American males have a higher incidence of prostate cancer than non-African-American males and an overall poorer prognosis. Environmental factors such as socioeconomic status and biological factors such as an increased frequency of androgen receptor mutation have been identified as causal. As
The antimutagenic properties of South African herbal teas were investigated using the Salmonella typhimurium mutagenicity assay. Aqueous extracts of fermented and unfermented rooibos tea (Aspalathus linearis) and honeybush tea (Cyclopia intermedia) both possess antimutagenic activity against
Although Burkitt's lymphoma (BL) can be treated by surgery, radiotherapy and immunotherapy, chemotherapy is the mainstay of treatment. This paper summarizes the various clinical trials undertaken in Africa over the past decade. The single most effective drug for BL is cyclophosphamide (CPM). Given
