Abstract:

Abstract In the course of our search for antimalarial leads from marine algae, four metabolites, sargaquinoic acid, sargahydroquinoic acid, sargaquinal and fucoxanthin, were isolated from the South African alga Sargassum heterophyllum. Fucoxanthin and sargaquinal showed good antiplasmodial activity toward a chloroquine-sensitive strain (D10) of Plasmodium falciparum (IC50 1.5 and 2.0 μm, respectively), while sargaquinoic acid and sargahydroquinoic acid were only moderately active (IC50 12.0 and 15.2 μm, respectively).

Abstract:

In South Africa the ultimate goal in water quality management is to keep the water resources suitable for all “beneficial uses”. Beneficial uses provides a basis for the derivation of water quality guidelines, which, for South Africa, are defined in Water quality guidelines for the South African coastal zone (DWAF, 1991). The CSIR has developed a practical approach to marine water quality management, taking into account international trends and local experience, which can be applied to any coastal development with potential influence on water quality. The management plan is divided into three

Abstract:

A recent policy of decentralizing growth in South Africa has led to the designation of neu coastal development areas. Growth of such areas, stimulated by the attraction of industries should be accompanied by a careful assessment of possible associated marine pollution problems. In particular, the disposal of industrial and/or domestic effluents to sea may initially appear an attractive option to planners and developers. Consequently the investigation of the feasibility of the marine disposal option is an essential component of the planning process. An on-going series of such studies in nominat

Abstract:

Malaria is one of the three most deadly diseases in Africa. Although there are available treatments, their efficacy has been greatly reduced over the past two decades due to the development of resistance to currently available drugs. This has necessitated the search for new and effective antimalarial agents. This project approached the search for new antimalarial compounds in two ways: (i) by screening natural products isolated from marine algae against the Plasmodium parasite and (ii) by modification of selected isolated active compounds to target 1-deoxY-đ-xylulose 5-phosphate reductoisomera

Abstract:

Secondary metabolites from natural sources are fast growing as popular drug leads. The structural novelty and favourable biological activity that these compounds display contribute to their popularity as drugs of the future. Examples of such compounds include the potent anticancer drug paclitaxel isolated from the bark of a yew tree as well as the more commonly known analgesic aspirin which stems from the bark of the willow tree. The biological activities exhibited by these secondary metabolites are vast and range from antimicrobial to anticancer activity to mention but a few. As a result, the

Molecular and chemical characterisation were used in conjunction with traditional taxonomy in identification of the sponge specimens.
