Since the last century, research groups and commercial companies in the field of pharmaceuticals but also the agrifood industry and biotechnological products have been generating, collecting, and storing a large amount of chemical information in large chemical libraries . These chemical libraries and collections of virtual compounds can be an exact reproduction of substances that exist in the scientist's laboratory or that can be acquired commercially, either natural products or synthetic compounds. Chemical libraries can also contain feasible virtual molecules according to simple chemical stability and synthetic feasibility rules generated by enumeration algorithms. The latter databases have the advantage of being able to synthesize substances on demand in case of need, for example after a virtual high-throughput screening.
