In 2005, Haristoy and coworkers investigated the activities of 12 isothiocyanates (ITC) and L-sulforaphane isolated from Cruciferous plant species in 25 strains of HP. Medicinal plants from the Cruciferae are well known to have chemopreventative effects on the GI tract, and are... 

Brassilexin 48 and sinalexin 49 are among the most potent phytoalexins produced by economically important cruciferous plants. The most efficient preparation of brassilexin 48, sinalexin 49, and analogues 52 reported uses a Vilsmeier formylation-amination of readily available indoline-2-thiones 50 followed by an aqueous ammonia work-up procedure with subsequent oxidation of the 3-(amino)methyleneindoline-2-thione intermediates 51 using iodine in pyridine (Scheme 10) <20010L1213, 2005JOC1828>. The reaction yields are dictated by the efficiency of the... 

Sinigrin (III), a glycoside produced by many species of cruciferous plants, can be converted to a highly toxic aglycone, allylisothiocyanate (IV), after hydrolysis by adapted and nonadapted Insects ( 5, 1, lA). On the other hand, the mustard oil is the preferred storage form of larvae of two Pieris species, brassicae and rapae, which had developed on food...

Disease control by green manure is an artificial application of allelopathy. Isothiocyanates released from cruciferous plants are an example of this allyl isothiocyanate (166), which is derived from the glucosinolate sinigrin (167), is the most popular example.98 Application of Geranium carolinianum for the control of Ralstonia solanacearum, the cause of bacterial wilt of potato, and potato scab, which is induced by some Streptomyces spp., was reported.99 100 One of the antibacterial constituents was shown to be ethyl gallate (168).101...

Four examples of structurally characterised, vanadate-inhibited phosphorylation enzymes working on the hydrolysis of phospho-ester bonds in nucleotides I, the vanadate-uridine complex of bovine pancreatic ribonuclease-A II, the vanadate complex of ribonuclease-Tj from the fungus Aspergillus oryzae-. III, the vanadate-uridine complex of cyclic nucleotide phosphodiesterase from the cruciferous plant Arabidopsis thaliana-, IV, human tyrosyl-DNA phosphodiesterase (Ur = uridine). 

Phytoestrogens are generally present at low levels and have lower activity than the main human oestrogen, 17(3-oestradiol (Fig. 7.9). Some can show anti-oestrogenic activity (Box 7.2), such as indole-3-carbinol (Fig. 7.11 present in cruciferous plants, e.g. sprouts and cabbage) and isoflavones. High levels of...

The isothiazole moiety is very rarely found in natural products. The fungicidal Brassilexin 6 was isolated from the leaves of the cruciferous plant Brassica juncea. This compound is a derivative of isothi-azoloindole [111] ... 

Although there is a common view that isothiocyanates are important odor components of intact brassicaceous plants, field levels are extremely low and are usually below the level of detection of the usual analytical techniques. The principal vapor component of turnip and radish is hexenyl acetate see Chapter 2). Even in the case of disrupted tissue of cauliflower, turnip, radish, and wallflower (Alyssum), the principal component was Z-hex-3-enyl acetate (Wallbank and Wheatley, 1976). These data suggest that green leaf volatiles may be involved in the attraction of many species of insects to cruciferous plants.
