Orthogonally Positioned Diamino Pyrrole- and Imidazole-Containing Polyamides: Synthesis of 1-(3-Substituted-propyl)-4-nitropyrrole-2-carboxylic Acid and 1-(3-Chloropropyl)-4-nitroimidazole-2-carboxylic Acid
摘要:
Pyrrole- and imidazole-containing polyamides can be tailored to recognize the DNA 6-8 base pair sequence. We found that adding a second amino group via the N1-position of pyrrole or imidazole in polyamides could enhance their DNA binding affinity and water solubility while retaining sequence specificity. Synthesis of the key 1-substituted-4-nitropyrrole (and imidazole)-2-carboxylic acid building blocks are described. [Supplementary materials are available for this article.
