Helicteres genus, Malvaceae, has pantropical distribution, encompasses about 60 species, 31 of them found in Brazil. Species belonging to this genus are used for treatment of various diseases and aroused scientific interest in search for bioactive compounds present in these plants. In this context, this review aims to provide a complete and concise overview of scientific advances in phytochemical and pharmacological studies of these species and their use by folk medicine. The presented data were collected from scientific databases, ‘Web of Science’, ‘Scifinder’, ‘Pubmed’, ‘Sciencedirect’, and ‘Google Scholar’, using the keyword ‘Helicteres’. The species H. isora and H. angustifolia, found in Asia, are the most explored scientifically, whereas studies of species of this genus found in Americas are still rare, being possible to highlight studies carried out in Brazil with H. velutina and H. eichleri. About 149 compounds were isolated and characterized in the genus, being emphasized terpenoids, flavonoids and lignoids. These species have demonstrated various pharmacological properties in vitro and in vivo, incluinding insecticide, antidiabetic, antitumor and hepatoprotective activities. The presented data show the importance of studies carried out isolating bioactive compounds from this genus that may be used in several diseases’ treatment or/as prototypes to development of new drugs.
