“…The genera Picramnia and Alvaradoa, despite occasionally reported as constituents of the Simaroubaceae family (Balderrama et al, 2001;Rodríguez-Gamboa et al, 2001;Cortadi et al, 2010), were excluded from it and put into the Picramniaceae family by Fernando and collaborators (1995). This translocation is supported by the fact that Picramnia and Alvaradoa are phytochemically characterized by a vast presence of anthraquinones and anthracenic derivates in comparison to quassinoids, the taxonomic markers of the Simaroubaceae family (Diaz et al, 2004).…”

“…Picramnia species (Picramniaceae, previously Simaroubaceae) are commonly used in folk medicine to treat or prevent dermatosis, external ulcers (sores), and skin irritations [ 4 ]. Phytochemical investigation in some of these Picramnia species resulted in isolation of several metabolites [ 5 , 6 ], mainly triterpenes [ 7 – 9 ], anthrones and anthraquinone glycosides [ 10 – 14 ], and oxanthrones [ 10 – 12 , 15 ] with cytotoxic, antimicrobial, antifungal, or antiparasitic activities [ 16 – 18 ]. Picramnia gracilis Tul.…”

Species of Picramnia genus are used in folk medicine to treat or prevent skin disorders, but only few species have been studied for biological activity and chemical composition. P. gracilis Tul. is a native species from Central and South America and although its fruits are edible, phytochemical analysis or medicinal uses of this species are not known. In the search of candidates to antileishmanial drugs, this work aimed to evaluate the antileishmanial activity of P. gracilis Tul. in in vitro and in vivo studies. Only ethanolic extract of fruits showed leishmanicidal activity. The majoritarian metabolite was 5,3′-hydroxy-7,4′-dimethoxyflavanone ether that exhibited high activity against L. (V.) panamensis (EC50 17.0 + 2.8 mg/mL, 53.7 μM) and low toxicity on mammalian U-937 cells, with an index of selectivity >11.8. In vivo studies showed that the flavanone administered in solution (2 mg/kg/day) or cream (2%) induces clinical improvement and no toxicity in hamsters with CL. In conclusion, this is the first report about isolation of 5,3′-hydroxy-7,4′-dimethoxyflavanone of P. gracilis Tul. The leishmanicidal activity attributed to this flavanone is also reported for the first time. Finally, the in vitro and in vivo leishmanicidal activity reported here for 5,3′-hydroxy-7,4′-dimethoxyflavanone offers a greater prospect towards antileishmanial drug discovery and development.
