Synthesis and photoinduced DNA cleaving activity of hairpin polyamide-chlorobenzenesulfonyl conjugates.


A hairpin polyamide-chlorobenzenesulfonyl conjugate was synthesized in solution by a haloform reaction and the dicyclohexylcarbodiimide/1-hydroxybenzotriazole (DCC/HOBT) coupling reaction. Its ability to cleave DNA was investigated with supercoiled DNA (pBluescript SK), and the DNA cleaving efficiency of chlorobenzenesulfonyl group was enhanced by the… (More)
