[摘要]：New 2-chloro-3-formyl quinoline oxime esters were synthesized by the reaction of 2-chloro-3-formyl quinoline oximes with various benzoyl chlorides in the presence of triethyl amine and dichloromethane at 0 degrees C. The DNA photo cleavage studies of some new oxime esters were investigated by neutral agarose gel electrophoresis at different concentrations (40 mu M and 80 mu M). Analysis of the cleavage products in agarose gel indicated that few of quinoline oxime esters (3d-i) converted into supercoiled pUC19 plasmid DNA to its nicked or linear form. (C) 2011 Elsevier Ltd.
