Naturally occurring phenethyl isothiocyanate (PEITC) and its synthetic homolog 6-phenylhexyl isothiocyanate (PHITC) are both effective inhibitors of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone-induced lung tumor development in A/J mice and F344 rats. To help explain why PHITC is considerably more efficacious than PEITC in chemopreventive potency, comparative disposition and pharmacokinetics ...

In the title compound, C(10)H(9)ClN(2)O(6), the two nitro groups and the ester group are oriented with respect to the benzene ring at dihedral angles of 49.42 (13)/87.61 (13) and 9.10 (10)°, respectively. In the crystal structure, a weak C-H⋯O inter-action is present. A short Cl⋯O contact of 2.972 (2) Å is also observed in the crystal structure.

The reversible reaction of GSH with two dietary anticarcinogens, benzyl isothiocyanate (BITC) and phenethyl isothiocyanate (PEITC), has been studied in the absence and presence of human glutathione S-transferases (GSTs). The spontaneous reaction at pH 7.4 and 37 degrees C yielded values for k2 of 17.9 and 6.0 M-1.s-1 for GSH conjugation of BITC and PEITC respectively (forward reaction), and k1 ...

1. A study has been made of the non-specific fluorescent staining of splenic imprints treated with fluorescent sheep antibody globulins. 2. In tissue imprints made with the spleens of antigen-stimulated animals, no morphological distinction was evident between areas showing non-specific fluorescence and specific fluorescence. 3. Elimination of non-specific fluorescence was not achieved by any o...

The present communication reports the comparison of in vivo antioxidant, antimelanoma and antimutagenic activities of Eruca sativa seed oil and its bio principles (allyl isothiocyanate, phenylethyl isothiocyanate and sulphoraphane) against B16F10 melanoma cells induced in C57BL/6 mice model. Among the various treatments considered for the study, isothiocyanates combination (allyl isothiocyanate...

Glucosinolates from seed meals of Erysimum hieracifoliwn and l\1alcolmia mantlma were treated with thioglucosidase (EC 3.2.3.1). and the resultant aglucon products investigated. A major product from E. hieracifoliwll was 3-hydroxypropyl isothiocyanate from the novel precursor 3-hydroxypropylglucosinolate. Other aglucon products were 3-methylsulfonylpropyL 3-methylsulfinylpropyl. 3-methylthiopro...
