Tris-arenes based on either isophthalic acid or 2,6-dipicolinic acid have been known for more than a decade to bind anions. Recent studies have also demonstrated their ability to transport various ions through membranes. In this report, we demonstrate two important properties of these simple diamides. First, they transport plasmid DNA into Escherichia colt about 2-fold over controls, where the ampicillin resistance gene is expressed in the bacteria. These studies were done with plasrnid DNA (similar to 2.6 kilobase (kb)) in JM109 E. coli cells. Second, known methods do not typically transport large plasmids (>15 kb). We demonstrate here that transformation of large pVIB plasmids (i.e., >20 kb) were enhanced over water controls by similar to 10-fold. These results are in striking contrast to the normal decrease in transformation with increasing plasmid size.
