on the other hand , cytostatic beta-chloroethyl hydrazones showed a negligible reactivity against glutathione and led even to an increase of thiol groups , detectable by the 5,5'-dithiobis-2-nitrobenzoic acid ( dtnb ) -method , at the cell membrane of eac when incubated in the presence of beta-chloroethyl hydrazones n-benzylidene-n'-methyl-n'- ( 2-chloroethyl ) hydrazine ( b1 ) and n- ( 4-dimethylaminobenzylidene ) -n'-methyl-n'- ( 2-chloroethyl ) hydrazine ( b2 ) .
