Vatairea guianenis Aubl. (Fabaceae) is an Amazonian medicinal plant species traditionally used for treating skin diseases. In an initial screening, a V. guianensis leaf extract and its subextracts showed antibacterial and antifungal activities. The EtOAc subextract was selected for chemical workup and afforded five known (1-4 and 8) and six undescribed isoflavones, vatairenones C-H( 5-7 and 9-11). All isoflavones are prenylated in position C-8, displaying either chain-prenylated (1-7) or ring-closed forms (8-11). The most bioactive compound (3) exhibited in vitro activity against clinically relevant bacteria and fungi with IC50 values ranging from 6.8 to 26.9 μM. Due to its broad antimicrobial activity and low general toxicity, compound 3 is a potential lead compound for structural modifications. The results of the present study support the ethnomedicinal use of V. guianensis in the treatment of dermatological disorders. 1H NMR spectra of some of the isolated compounds showed intricate signal patterns, which might explain repeated errors in assigning the correct structure of the isoflavonoid B-ring in the literature and which we resolved by higher order spectra simulations. |

Abstract: The intense growth of fish farming in Brazil requires an operational monitoring of water quality. Water transparency is an important parameter to investigate the biological balance in productive waters. Empirical algorithms based on remotely sensed data can be used to monitoring the spatial and temporal variability in such productive system. This work aimed to map the water transparency in caged-fish farm from space and to evaluate the short-term impact of this activity on eutrophication. The results showed that the empirical algorithm (band ratio 443/665 nm) was satisfactory for study area (MAPE = 17.5%) and the water transparency was an indicator of algal presence in fish farms. |
