  • Samuel Egieyeh

    Dr. Samuel Ayodele Egieyeh is a seasoned and experienced (over 20 years) pharmacist with B.Pharm (University of Lagos, Nigeria), M.Pharm (University of the Western Cape, Cape Town South Africa) and Ph.D. in Bioinformatics (University of the Western Cape, Cape Town South Africa). He also has post-graduate certificates in clinical research and drug development from the University of Basel, Basel Switzerland. He started his career as a research fellow in 2001 at the Department of Pharmaceutics and Pharmaceutical Technology, National Institute for Pharmaceutical Research and Development (NIPRD), Abuja Nigeria where he was involved in the formulation, production and quality control of herbal products (a remedy for sickle cell anemia and malaria). He was later posted, as a pharmacist in charge, to the Antiretroviral Therapy Clinic where implemented various pharmaceutical care strategies for HIV infected clients under the Presidential Emergency Plan For AIDS Relief (PEPFAR) project. In 2008, he joined the International Centre for Genetic Engineering and Biotechnology (ICGEB), Cape Town component for a two-year research fellowship. He is currently a lecturer at the Department of Basic pharmacology and Clinical Pharmacy, School of Pharmacy, University of the Western Cape, Bellville South Africa. He is also a facilitator for the University of the Western Cape-Healthcare Learning post-graduate programme (Masters of Science in Pharmaceutical Medicine and Regulatory Sciences). His research focuses on computational drug discovery, design and development, analysis and interpretation of chemical and bioactivity data using Cheminformatics, Bioinformatics, Machine Learning and Biostatistics techniques in conjunction with relevant in-vitro bioassays in order to discover and design novel drug candidates, especially from natural products, for infectious and non-infectious diseases.

Abstract

A large number of natural products, especially those used in ethnomedicine of malaria, have shown varying in vitro antiplasmodial activities. Facilitating antimalarial drug development from this wealth of natural products is an imperative and laudable mission to pursue. However, limited manpower, high research cost coupled with high failure rate during preclinical and clinical studies might militate against the pursuit of this mission. These limitations may be overcome with cheminformatic techniques. Cheminformatics involves the organization, integration, curation, standardization, simulation, mining and transformation of pharmacology data (compounds and bioactivity) into knowledge that can drive rational and viable drug development decisions. This chapter will review the application of cheminformatics techniques (including molecular diversity analysis, quantitative-structure activity/property relationships and Machine learning) to natural products with in vitro and in vivo antiplasmodial activities in order to facilitate their development into antimalarial drug candidates and design of new potential antimalarial compounds.
