The formation of 0-seryl or 0-prolyl esters (Figure 1) of certain N-hydroxy arylamines has been inferred from the observations that highly reactive intermediates can be generated in vitro by incubation with ATP, serine or proline, and the corresponding aminoacyl tRNA synthetases (11,12,119). For example, activation of N-hydroxy-4-aminoquinoline-l-oxide (119,120), N-hydroxy-4-aminoazobenzene (11) and N-hydroxy-Trp-P-2 (121) to nucleic acid-bound products was demonstrated using seryl-tRNA synthetase from yeast or rat ascites hepatoma cells. More recently, hepatic cytosolic prolyl-, but not seryl-, tRNA synthetase was shown to activate N-hydroxy-Trp-P-2 (12) however, no activation was detectable for the N-hydroxy metabolites of AF, 3,2 -dimethyl-4-aminobiphenyl, or N -acetylbenzidine (122).

Evidence for increased transport of " C-labelled nitrogen mustard N-oxide through rat ascites hepatoma cell membranes by polysorbate 80 [164] and the recent observation that this surfactant can increase methotrexate uptake into the brain [82a] gives rise to hope that surfactants can play a useful role in modification of drug action in specialized forms of treat-...
