High consumption of Brassica vegetables is considered to prevent especially colon carcinogenesis. The content and pattern of glucosinolates (GSLs) can highly vary among different Brassica vegetables and may, thus, affect the outcome of Brassica intervention studies. Therefore, we aimed to feed mice with diets containing plant materials of the Brassica… (More)
Molecular modelling studies resulted in the design of a variety of non-nucleotidic covalent linkers to bridge the 3'-end of the (+)-strand and the 5'-end of the (-)-strand in DNA duplexes. Three of these linkers were synthesized and used to prepare singly cross-linked duplexes d(GTGGAATTC)-linker-d(GAATTCCAC). Linker I is an assembly of a propylene-, a… (More)
Efficient solid-phase synthesis of a series of oligoribonucleotides of up to 20 residues is described that utilises the 9-fluorenylmethoxycarbonyl group (Fmoc) for 5'-protection and 4-methoxytetrahydropyran-4-yl (Mthp) for 2'-protection of ribonucleotide monomers and a phosphoramidite coupling procedure. The Fmoc group is removed after each coupling step by… (More)
Many popular synthesis strategies look for appropriate 2'-O-protection methods to use in conjunction with 5'-O-trityl chemistry. In contrast, this unit describes the use of FMOC as a 5'-protecting group in conjunction with a ketal-type 2'-O-protecting group, 4-methoxytetrahydropyran-4-yl (MTHP). The synthesis of all four 2'-O-MTHP-5'-O-FMOC-protected… (More)
An efficient method is described for solid-phase synthesis of oligoribonucleotides that involves use of the 9-fluorenylmethoxycarbonyl group (Fmoc) for 5'-protection, 4-methoxytetrahydropyran-4-yl (Mthp) for 2'-protection and a phosphoramidite coupling procedure.
Various analytical methods have been established to quantify isothiocyanates (ITCs) that derive from glucosinolate hydrolysis. However, to date there is no valid method applicable to pharmacokinetic studies that detects both glucosinolates and ITCs. A specific derivatization procedure was developed for the determination of ITCs based on the formation of a… (More)
