The synthesis of a series of 12 N-(2-fluorenyl)hydroxamic acids, N-(2-fluorenyl)-N-hydroxyureas, and N-(2-fluorenyl)-N-hydroxycarbamates is reported.The compounds were evaluated for their ability to serve as substrates for a partially purified hamster hepatic arylhydroxamic acid N,O-acyltransferase preparation.Transacylating activity was measured spectrophotometrically with 4-aminoazobenzene as the acyl group acceptor, and electrophile-generating activity was quantified by the N-acetylmethionine trapping assay.Only the N-acetyl, N-propionyl, and N-methoxyacetyl derivatives exhibited relatively high levels of activity as measured by either of the assay methods.These results are generally consistent with previously reported conclusions regarding the steric and electronic characteristics of acyl groups that are required for activation by this enzyme system.N,O-Acyltransferase inactivation by N-hydroxy-2-acetamidofluorene depressed the bioactivation of the N-acetyl compound to a greater extent than either the N-propionyl or N-methyloxyacetyl derivative.
