Title: Anticancer potentials of phytochemicals from indigenous west African plants

Biography

Biography: Joseph O Nwankwo

Abstract

Many indigenous west African plants have been employed as local remedies for various human ailments in the traditional medicine of the region and as nutritional sources for countless generations. Isolation and characterization of the chemical structures for phytochemicals from useful indigenous plants have however been undertaken only for a minimal fraction largely, because the modern techniques of chromatography and mass spectroscopy have been exploited by African scientists relatively, recently. The significance of the latter development has been to greatly enhance an understanding of the molecular mechanisms of action for these isolated compounds as pharmacological agents. In particular, such knowledge has been applied in the present discussion to identify indigenous west African phytochemicals with potential anticancer activities based on their structure-activity relationships to known active compounds – an outcome totally unanticipated by the organic chemists who merely isolated and characterized these phytochemicals. The compounds are grouped as potential “Cancer Chemopreventive” and “Cancer Chemotherapeutic” agents and cover most of the known phytochemical classes of alkaloids, flavonoids, lignans, quinones, terpenoids and ‘miscellaneous’, the latter class comprising compounds considered chemically inappropriate for the previous classes. Such identified compounds still await relevant biological activity tests before confirmation of suggested anticancer potentials.
