1. PHYTOTOXIC CONSTITUENTS FROM ENDOPHYTIC FUNGUS Xylaria cubensis ASSOCIATED WITH Eugenia brasiliensis
The upscaling of Xylaria cubensis, an endophyte of Eugenia brasiliensis (Myrtaceae), in PDB medium led to the isolation of known compounds including cytochalasin D (7) and cytochalasin C (8), which exhibited relatively higher phytotoxic activity in all the concentrations tested compared to the commercial herbicide GOAL®. Besides the aforementioned metabolit

2. In vivo chemotherapeutic insight of a novel isocoumarin (3-hexyl-5,7-dimethoxy-isochromen-1-one): Genotoxicity, cell death induction, leukometry and phagocytic evaluation
Abstract Chemotherapy is one of the major approaches for the treatment of cancer. Therefore, the development of new chemotherapy drugs is an important aspect of medicinal chemistry. Chemotherapeutic agents include isocoumarins, which are privileged structures with potential antitumoral activity. Herein, a new 3-substituted isocoumarin was synthesized from 2-

3. Estudo de modelagem molecular e de inibição enzimática das calicreínas teciduais humanas 5 e 7 por compostos isocumarínicos e derivados de isomanídeos
A família das calicreínas teciduais humanas é composta de quinze serino proteases, sendo o gene denotado por KLK e a proteína por KLK seguida do número correspondente. Elas apresentam atividade semelhante à tripsina, com exceção das KLK3, 7 e 9 que apresentam atividade semelhante à quimotripsina. São transcritas como pré-pró-enzimas, sendo que ap

4. Analysis of secondary metabolites produced by endophytic fungi associated to Cupressus lusitanica / Análise de metabólitos secundários produzidos por fungos endofíticos associados à Cupressus lusitanica
Some phytopatogenic fungi found in Cupressus species produces phytotoxins very aggressive to the host plant. Surprisingly, these toxins are diterpenoids structures, as well as some endogenus metabolites in Cupressus species. This fungi ability appears to be a specialized strategy in the association fungi-plant. These observations motivated the development of

5. Synthesis, herbicidal, fungicidal and insecticidal evaluation of 3-(dichlorophenyl)- isocoumarins and (±)-3-(dichlorophenyl)-3,4-dihydroisocoumarins
Este é o primeiro relato mostrando que 3-(diclorofenil)isocumarinas e (±)-3,4-(dihidroisocumarinas) são inibidores do crescimento de plantas e fungos. 3-Diclorofenilisocumarinas foram sintetizadas pela condensação de ácido homoftálico com cloretos de diclorobenzoíla. A hidrólise alcalina destas isocumarinas formou ceto ácidos. 3-(Diclorofenil)-3,4-

6. Study of the metabolism of Xylaria sp., na endophyte fungus isolated from the fruits of Sapindus saponaria / Contribuição ao estudo do metabolismo micromolecular de Xylaria sp., um fungo endofítico isolado de Sapindus saponaria
This work reports the study of a surprising plant microorganism relationship, involving the plant Sapindus saponaria, which is rich in antigungal saponins, and an endophyte fungus isolated from the pericarpe of the fruits collected in the host plant, and identified as Xylaria sp. The main objective of this work was to understand the survival mechanism of thi
