Stabilizing G-quadruplex DNA by methylazacalix[n]pyridine through shape-complementary interaction

Different with MACPn (n = 4, 7, 8, 9), MACP6 can selectively stabilize the 12 bp intermolecular G-quadruplex by shape-complementary mode. MACP6 also can discriminate the parallel and antiparallel forms of T12 G-quadruplex.63
