Abstract: In order to fulfill research objectives around target-based drug discovery in the field of anti-infective agents that are prevalent mainly in poor Third World countries, selection of biological and chemical targets is guided by economic drug discovery and rational medicinal chemistry. Selection of biological targets of therapeutic relevance in multiple disease-causing organisms, as well as the use of natural products and existing drugs as chemical scaffolds for the discovery and design of novel therapeutics should be viable strategies underpinning drug discovery research in poor Third World countries. In this regard, biological targets of interest to our program include disulfide reductases and cysteine proteases (CPs), while chemical scaffolds include existing antimalarial agents and natural products.
