Abstract
Nature is considered a prolific source of diverse biologically active chemotypes. While most reviews have focused on the characteristics of the chemical backbones of natural products (NPs), few have tried to provide an overview of their origins (the living organisms in which they are produced), chemical classes, and biological activities. This review discusses the current knowledge on NP diversity by focusing on the Dictionary of Natural Products® (DNP). We datamined the 300,000 NPs covered by the DNP to reveal relevant, albeit dormant, knowledge about NP diversity. This holistic picture of NPs allows us to discuss the most abundant biological sources of NPs investigated in relation to their chemical features and biological activities. In a nutshell, a large part of NPs originated from plants (67%), especially from the Compositae and Leguminosae families. Among all kingdoms, NPs isolated from Streptomyces spp. were largely represented, while terpenoids and alkaloids were the two most represented chemical classes. Out of all NPs documented, only 3882 were reported to be bioactive (1163 from plants and 1006 from bacteria), with antibacterial, antibiotics, and antineoplastic agents being the most frequent therapeutic classes. In this paper, we also address the advantages and limitations of NP research from a pharmaceutical industry perspective. This work will provide useful insights and guidance to researchers involved in drug discovery from NPs.
