title: Programmable oligomers targeting 5'-GGGG-3' in the minor groove of DNA and NF-kappaB binding inhibition.
abstract: A series of hairpin oligomers containing benzimidazole (Bi) and imidazopyridine (Ip) rings were synthesized and screened to target 5'-WGGGGW-3', a core sequence in the DNA-binding site of NF-kappaB, a prolific transcription factor important in biology and disease. Five Bi and Ip containing oligomers bound to the 5'-WGGGGW-3' site with high affinity. One of the oligomers (Im-Im-Im-Im-gamma-Py-Bi-Py-Bi-beta-Dp) was able to inhibit DNA binding by the transcription factor NF-kappaB.
