Abstract

Natural products represent a promising strategy for the discovery of new drug leads. Despite the effort of industry and academia, the investigations of natural products are concentrated in tropical and sub-tropical areas. Polar regions, such as the Arctic and Antarctica, are the most extreme and isolated environments on earth. Indeed, their severe climate conditions include low temperatures, high ultraviolet radiation, freeze–thaw cycles, and strong winds. These regions harbor a rich and underexplored biodiversity with immeasurable aggregate biotechnological potential. To survive on the poles, organisms have evolved and acquired different strategies including distinctive biological machineries, leading to the production of a unique and diverse array of organic molecules which can be used as prototypes for the development of new therapeutic agents. In this review, we summarize the occurrence of secondary metabolites from the Arctic and Antarctic organisms as well as their bioactivity from 2018 to 2020. Besides, we illustrate the collection sites and countries contributions to the field of polar natural products.
