Abstract
Marine organisms offer a delicate, yet plentiful source for a vast array of
novel products whose unique structural features make them suitable drug candidates,
pesticides, marine anti-fouling agents, and more. There are many challenges that
threaten the marine ecosystems like climatic change, biological invasions,
overexploitation, overfishing, and water pollution. These challenges negatively affect
the marine biodiversity and then productivity. So, they must be overcome for potential
preservation of various lives in the marine environment. The current chapter will
present various opportunities in marine drug discovery and will also discuss the
problems encountered in marine drug discovery.
