  Phenylalkyl isothiocyanate-cysteine conjugates as glutathione S-transferase stimulating agents

  摘要：

  To develop analogues of phenylalkyl isothiocyanate with less toxicity and better biological activity, two water-soluble phenylalkyl isothiocyanate-cysteine conjugates, S-[N-benzyl(thiocarbamoyl)]-L-cysteine (1) and S-[N-(3-phenylpropyl)thiocarbamoyl)]-L-cysteine (2), were synthesized. The induction of increased activity of the detoxifying enzyme glutathione S-transferase by the conjugates and their parent compounds was determined and compared in several tissues of A/J mice. The biological evaluation revealed that the conjugates as GST enzyme inducers appeared to be less toxic and even more potent than the parent compounds in the mouse bladder. Compounds 1 was much more active than 2 in all the tissues examined, while their parent compounds showed an inverse order of activity. Thus, an increase in the alkyl chain length of the parent isothiocyanates or a decrease in the alkyl length of the conjugates could result in higher enzyme-inducing activity m the same compound series. Since a number of nitrosamines have been identified as prime bladder carcinogens and phenylalkyl isothiocyanates have been reported to inhibit a wide range of carcinogenic nitrosamines, the corresponding conjugates may serve as prodrugs to protect against nitrosamine-induced urinary bladder carcinogenesis once they are delivered to the target organ.

• Inhibition of human leukaemia 60 cell growth by mercapturic acid metabolites of phenylethyl isothiocyanate

  Mercapturic acid pathway metabolites of phenylethyl isothiocyanate inhibited the growth of human leukaemia 60 (HL60) cells in vitro. The adduct with L-cysteine, S-(N-phenylethylthiocarbamoyl)cysteine, was the most potent with strong antileukaemic activity: the median growth inhibitory concentration (GC(50)) value was 336 +/- 1 nM (N = 18) compared with GC(50) values of the precursor formed from dietary glucosinolates, phenylethyl isothiocyanate, 1.49 +/- 0.01 mu M (N = 8), and the initial mercapturic acid pathway metabolite S-(N-phenylethylthiocarbamoyl)glutathion 5.46 +/- 0.36 mu M (N = 18). S-(N-Benzylthiocarbamoyl)cysteine and S-(N-phenylpropylthiocarbamoyl)cysteine also had antiproliferative activity but S-(N-phenylethylthiocarbamoyl)cysteine was the most potent compound studied. The latter induced DNA fragmentation in HL60 cells but DNA laddering characteristic of apoptosis was not observed. It had low toxicity to corresponding differentiated cells, neutrophils, in culture, and therefore the cytotoxicity had selectivity for leukaemia cells. The antiproliferative activity of S-(N-phenylethylthiocarbamoyl)cysteine was lost during preincubation with culture medium, attributed to S-thiocarbamoyl transfer to serum proteins, which may decrease its effectiveness in vivo. The antiproliferative activity of S-(N-phenylalkylthiocarbamoyl)cysteine derivatives, by inhibiting tumour growth in pre-clinical development, may contribute to the association of decreased cancer incidence with dietary glucosinolate consumption.
