  • Title: Influence of benzo[a]phenothiazines on the element content of two tobacco tissue cultures differing in hormone requirement.
    Author: Szabó M, Csiszár J, Rausch H, Molnár J, Motohashi N.
    Journal: Anticancer Res; 1997; 17(3C):2049-56. PubMed ID: 9216663.
    Abstract:
    Cell proliferation and tumor formation are closely connected with hormone metabolism. We report the effect of four benzo[a]phenothiazines (12H-benzo[a]phenothiazine (1), 5-oxo-5H-benzo[a]phenothiazine (2), 10-methyl-12H-benzo[a]phenothiazine (3), and 6-hydroxy-5-oxo-5H-benzo[a]phenothiazine (4) on the growth and changes in the element compositions (Ca, Cl, Cu, I, K, Mg, Mn and Na) of auxin autotrophic and heterotrophic tobacco tissue cultures. The concentration levels of these ions were followed by means of reactor neutron activation analysis.
