  Evaluation of PI polyamide conjugates with eight-base pair recognition and improvement of the aqueous solubility by PEGylation

  摘要：

  To investigate the effect of elongating base-pair (bp) recognition sequences, we synthesized N-methylpyrrole-N-methylimidazole (PI) polyamide conjugates with eight-bp recognition (3-5). The DNA alkylating activities of conjugates 3-5 were evaluated by high-resolution denaturing polyacrylamide gel electrophoresis with a 208-bp DNA fragment. Conjugates 3-5 showed high alkylating activities at nanomolar concentrations.We then addressed the following issue about PI conjugates. Generally, PI polyamide conjugates hardly dissolve in aqueous solution. To improve the aqueous solubility, by the introduction of hydrophilic groups, we synthesized PI polyamide conjugates that were modified with a seco-CBI moiety (6-11). Conjugates 9-11 that were modified by methoxypolyethylene glycol (PEG) 750 acquired moderate solubility and stability in aqueous solution. In addition, conjugates 10 and 11 had high cytotoxicity against A549 and DU145. (C) 2011 Elsevier Ltd. All rights reserved.
