Tuning urea–phenanthridinium conjugates for DNA/RNA and base pair recognition
摘要:
A series of novel urea-phenanthridine conjugates was prepared. The variation of linker length connecting two urea-phenanthridinium conjugates regulated their binding mode toward double stranded polynucleotides, consequently controlling selectivity of compounds toward ds-RNA over ds-DNA stabilization as well as selective fluorescence response toward addition of G-C base pair and A-U(T) base pair containing polynucleotides.
