1. NEW SEMISYNTHETIC DERIVATIVES OF A BENZYLISOTHIOCYANATE ISOLATED FROM Moringa oleifera AND EVALUATION OF THEIR CYTOTOXIC ACTIVITY
From the natural product 4-(4'-O-acetyl-α-L-rhamnosyloxy)benzylisothiocyanate (1), isolated from the flowers of Moringa oleifera Lam (Moringaceae), four new semisynthetic derivatives, N-[4-(4'-O-acetyl-α-L-rhamnosyloxy)benzyl]-2-(pyridinil-4-carbonil)hydrazine-1-carbothioamide (3), 4-(4'-O-acetyl-2',3'-dimesyloxy-α-L-rhamnosyloxy)benzylisothiocyanate (4),

2. Propriedades citotÃxica, genotÃxica e antitumoral de um benzil-isotiocianato isolado de Moringa oleifera (MORINGACEAE). / Cytotoxic, genotoxic and antitumor properties of the a benzyl-isothiocyanate isolated from Moringa oleifera (MORINGACEAE).
Moringa oleifera Lam. à uma planta tropical com grande importÃncia por seus usos medicinais. VÃrios compostos jà foram isolados de diferentes partes da planta, e dentre as atividades farmacolÃgicas podemos destacar a antitumoral. Este trabalho determinou, inicialmente, a atividade citotÃxica, por MTT, do composto 4-(4′-O-acetil-α-L-ramnopira

3. Antifungal Activity of Isothiocyanates and Related Compounds: I. Naturally Occurring Isothiocyanates and Their Analogues
Data are presented concerning the antifungal activity of 11 natural isothiocyanates and 27 synthetized analogues in Aspergillus niger, Penicillium cyclopium, and Rhizopus oryzae, as well as in 13 additional saprophytic and parasitic fungi. A remarkable antifungal activity was observed in some analogues of benzylisothiocyanate and β-phenylethylisothiocyanate

4. Synthesis of Benzylglucosinolate in Tropaeolum majus L. (Isothiocyanates as Potent Enzyme Inhibitors).
Benzylglucosinolate accumulates in mature plants of Tropaeolum majus L. The biosynthetic capacity for synthesis of benzylglucosinolate and the total content of benzylglucosinolate have been investigated during plant development and in different tissues. The content increased from 5 mg of benzylglucosinolate in the fresh seed to between 200 and 400 mg in the

5. Isolation of a Microsomal Enzyme System Involved in Glucosinolate Biosynthesis from Seedlings of Tropaeolum majus L.
An in vitro system that converts phenylalanine to phenylacetaldoxime in the biosynthesis of the glucosinolate glucotropaeolin has been established in seedlings of Tropaeolum majus L. exposed to the combined treatment of jasmonic acid, ethanol, and light. The treatment resulted in a 9-fold induction, compared with untreated, dark-grown seedlings, of de novo b

6. Induction of NAD(P)H:quinone reductase in murine hepatoma cells by phenolic antioxidants, azo dyes, and other chemoprotectors: a model system for the study of anticarcinogens.
Exposure of murine hepatoma (Hepa 1c1c7) cells to a variety of chemical agents known to protect animals against the neoplastic, mutagenic, and other toxic effects of chemical carcinogens results in dose- and time-dependent inductions of NAD(P)H:quinone reductase (EC 1.6.99.2). This enzyme protects against quinone toxicity by promoting obligatory two-electron
