Don from Azores Archipelago (Portugal) were analyzed by GC and GC-MS. Two populations, of black and reddish heartwood color, were studied. The main compounds found in the foliage of both populations were ƒÑ-pinene (9.6-29.5%), (+)-phyllocladene (3.5-26.5%), ent-kaur-16-ene (0.2-20.6%), sabinene (0.5-19.9%) and limonene (1.4-11.5%), with ...
Evaluation of the antifungal activity and mode of action of Lafoensia pacari A....
Silva Junior,Iberê F.; Raimondi,Marcela; Zacchino,Susana; Cechinel Filho,Valdir; Noldin,Vânia F.; Rao,Vietla S.; Lima,Joaquim C. S.Stem-bark extracts, fractions and the isolated constituent, ellagic acid of Lafoensia pacari St. Hil. (Lythraceae) were in vitro assayed for antifungal activity against a panel of yeasts, hialohyphomycetes as well as dermatophytes with the microbroth dilution method. The EtOH extract and its fractions and ellagic acid exhibited activity against Candida spp and Saccharomyces cerevisiae with MIC values between 25...
Synthesis of new 4-methyl-2-(4-pyridyl)-1,2,3,4-tetrahydroquinolines as potent ...
Méndez,Leonor Y. Vargas; Zacchino,Susana A.; Kouznetsov,Vladimir V.Synthesis, spectral characterization and biological results of new series of 2-(4-pyridyl)-1,2,3,4-tetrahydroquinolines and their closer precursors, -N-aryl-N-[1-(4-pyridyl)but-3-enyl]amines are reported. It was found that both γ-pyridyl substituted precursors and final products, tetrahydroquinolines, showed very good antifungal activities against Aspergillus fumigatus, Aspergillus flavus, Aspergillus nige...
