Juglone is a metabolite produced by several species of plants, in particular Juglans nigra. Additionally, juglone is a 1,4-naphthoquinone that has several biological actions. Antimicrobial, antifungal, sedative, oxidizing, antihypertensive, and especially anti-proliferative actions have been described for juglone. This justifies that 1,4-naphthoquinone is a privileged structure for Medicinal Chemistry, and it is useful for the development of new prototypes with varied actions. In this work, we make a profound review of juglone synthesis methodology, the biological actions of juglone, and mainly the synthesis and pharmacological actions of juglone derivatives. We hope that the potent biological actions described for these derivatives in this review will stimulate the continuous design, synthesis, and pharmacological evaluation of new juglone derivatives.
