1. ESTIRIL-LACTONAS DE Cryptocarya aschersoniana Mez. (Lauraceae Juss.) COM ATIVIDADE CONTRA Meloidogyne spp. E INTERAÇÃO IN SILICO COM PROVÁVEL FUMARASE DEMeloidogyne hapla
In a previous study, substances with nematicidal properties were detected in the bark of Cryptocarya aschersoniana. Continuing such study, the methanol extract from this plant underwent fractionation guided by in vitro assays with the plant-parasitic nematode Meloidogyne exigua. Two active compounds were isolated and identified by spectroscopic methods as (E

2. Sintese total da (-)-aza-isoaltolactona / Total synthesis of (-)-aza-isoaltholactone
Natural products are a rich source of medicinal compounds, and have also inspired the design of non-natural product of relevant pharmaceutical importance. The structure-activity relationship in natural product are an interesting area for research. In this work, we describe the synthesis of (-)-aza-isoaltholactone, an analogous of the (-)-isoaltolactone. The

3. Goniotalamina, epoxigoniotalamina, argentilactona e derivados : sinteses totais e atividades antiproliferativas contra celulas tumorais humanas / Goniothalamin, goniothalamin oxide and argentilactone: total syntheses and antiproliferative activies against cells of human cancer
Natural goniothalamin (24), goniothalamin oxide (25) and argentilactone (23) are 5,6-di-hydro-2H-pyran-2-one that display many interesting biological activities. The total syntheses of these natural products as well as some of their derivatives are described. Goniothalamin (24) was synthesized via catalytic asymmetric allylation of a-benzyloxyacetaldehyde (3
