Abstract

Natural beings contain an extraordinary diversity of bioactive molecules, which have been used as a source of medicines since the Antiquity. The majority of the available drugs in the market, are or derive from natural products. During the last 50 years, the research for the development of new drugs from natural substances has focused on the marine environment. Marine organisms have been comparatively less explored than terrestrial ones and are thought to produce unusual chemical structures because of the particular physical characteristics of marine waters. The interactions mediated by bioactive substances are widespread among marine beings, since they inhabit a low-visibility environment where the chemical cues become particularly relevant. Moreover, besides vegetables (algae), in the sea, there is an animal form of life that does not exist in the terrestrial environment. This form of life is represented by sessile invertebrates (attached to the sea bottom as adults), which are particularly prone to develop a set of mechanisms to avoid being covered by other fast-growing organisms (epibionts) or predated by mobile animals. Among these mechanisms, the production of defensive chemicals is preponderant, and these chemicals have been found applications in the pharmacological industry. In this study, I describe the way the investigation on new drugs of marine origin has developed in parallel to that on natural products and on chemical ecology and how this research field is a model in which basic and applied sciences go close together. Furthermore, I review the state of the art of the research in these fields and outline the current research topics and their foreseeable evolution in the forthcoming years.
