The effect of the EtOAc extract of leaves against (trypomastigotes) was evaluated . As this extract caused 100% parasite reduction (at 300 µg/mL), it was subjected to chromatographic fractionation to obtain two related diterpenes, clerodermic () an...
Chemical compositions of essential oils (EOs) from (EO-PG), (EO-LA) and (EO-CO) flowers were determined by GC-MS and GC-FID. Antibacterial activities were determined by the microdilution broth method in 96-well culture plates and MIC and MBC value...
Nine amide derivatives inspired by capsaicin (ADICs) were synthesised and evaluated for antibacterial and antitumor activities by a series of standard methods in this study. The results showed that ADICs had good antibacterial and antitumor activity....
Oxazines and their derivatives are an uncommon natural heterocyclic compounds, which contain oxygen and nitrogen atoms and possess various bioactivities. A novel 1,4-oxazine-xanthone derivative, fusarioxazin () and three known sterols () were separat...
A new diarylhexane, kneglobularone B () and two new diarylpropanols, kneglobularols A - B () along with seven known compounds () were isolated and characterized from the roots of It is the first time to find arylpropyl quinone () and isoflavone () i...
New talaromydien A and talaroisocoumarin A (), together with nine known compounds (-), were isolated from a culture of the marine-derived sp. ZZ1616 in potato dextrose broth medium. Structures of the new compounds were elucidated based on their HRE...
is an opportunistic agent that can cause a variety of infections, both hospital and community-acquired. Epigallocatechin gallate (EGCG), a flavonoid present in the leaves of , has different biological activities, including antimicrobial potential. H...
During the systematic screening of bioactive compounds from our marine natural product library, crude extract of the marine-derived fungus strain MF029 exhibited moderate bioactivities against , S, methicillin-resistant , and bacillus Calmette-Guér...
In this work was to develop an inedited nanocapsule with tucumã oil (). The oil presents of phytosterols (squalene and β-sitosterol), --beta-carotene, acids oleic and palmitic. Antioxidant activity showed a good performance in DPPH and ABTS assays. T...
The aim of the study was to isolate digestive enzymes inhibitors from through a bioassay-guided fractionation approach. Repeated silica gel and sephadex LH 20 column chromatographies of bioactive fractions afforded stigmasterol, quercetin and avicul...
