| + | AGRO100 (also known as AS1411) is a G-rich oligonucleotide that has long been established as a potent anti-cancer aptamer. However, the structure of AGRO100 remained unresolved, due to the co-existence of multiple different G-quadruplex conformations. We identified a DNA sequence named AT11, derived from AGRO100, which formed a single major G-quadruplex conformation and exhibited a similar anti-proliferative activity as AGRO100. The solution structure of AT11 revealed a four-layer G-quadruplex comprising of two propeller-type parallel-stranded subunits connected through a central linker. The stacking between the two subunits occurs at the 3Î-end of the first block and the 5Î-end of the second block. The structure of the anti-proliferative DNA sequence AT11 will allow greater understanding on the G-quadruplex folding principles and aid in structural optimization of anti-proliferative oligonucleotides. | ||
