M. Szabo et al., INFLUENCE OF BENZO[ALPHA]PHENOTHIAZINES ON THE ELEMENT CONTENT OF 2 TOBACCO TISSUE-CULTURES DIFFERING IN HORMONE REQUIREMENT, Anticancer research, 17(3C), 1997, pp. 2049-2056
Cell proliferation and tumor formation are closely connected with horm
one metabolism. We report the effect of four benzo[a]phenothiazines (1
2H-benzo[a]phenothiazine (1), 5-oxo-5H-benzo[a]phenothiazine (2), 10-m
ethyl-12H-benzo[a]phenothiazine (3), and 6-hydroxy-5-oxo-5H-benzo[a]ph
enothiazine (4) on the growth and changes in the element compositions
(Ca, Cl, Cu, I, K, Mg, Mn and Na) of auxin autotrophic and heterotroph
ic tobacco tissue cultures. The concentration levels of these ions wer
e followed by means of reactor neutron activation analysis.
