| + | The sequence-dependent DNA secondary structures possess structure polymorphism. To date, studies on regulated ligands mainly focus on individual DNA secondary topologies, while lack focus on quadruplex-duplex hybrids (QDHs). Here, we design an organic-metal hybrid ligand L(1) Pt(dien), which matches and selectively binds one type of QDHs with lateral duplex stem-loop (QLDH) with high affinity, while shows poor affinity for other QDHs and individual G4 or duplex DNA. The solution structure of QLDH MYT1L-L(1) Pt(dien) complex was determined by NMR. The structure reveals that L(1) Pt(dien) presents a chair-type conformation, whose large aromatic "chair surface" intercalates into the G-quadruplex-duplex interface via pi-pi stacking and "backrest" platinum unit interacts with duplex region through hydrogen bonding and electrostatic interactions, showing a highly matched lock-key binding mode. Our work provided guidance for spatial matching design of selectively targeting ligands to QDH structures. | ||
