Discovery of antibacterial lead compounds from marine organisms

Abstract

Marine organisms including algae and bacteria are known to produce chemically diverse secondary metabolites for survival purposes in the marine environment. Scientists have identified some of these natural products as therapeutic agents including some antibiotics. Given the increase in the resistance of pathogenic microorganisms especially methicillin-resistant Staphylococcus aureus (MRSA) and Mycobacterium tuberculosis to commonly prescribed antibiotics, researchers have turned towards exploiting marine natural products for new antibacterial compounds. Due to the proven success of finding bioactive compounds in the marine environment this study therefore aims to discover lead compounds against MRSA and Mycobacterium tuberculosis from two marine sources, the marine algae and the bacteria associated with marine invertebrates referred to as bacterial isolates.
