Synthesis of small multifunctional molecules having nucleic acid binding property

Area of Science:

• Synthetic chemistry
• Molecular biology
• RNA therapeutics

Background:

• Previously developed multifunctional conjugates efficiently cleaved target double helical RNA.
• Acridine derivatives served as intercalative molecules, and polyamine moieties acted as RNA cleaving agents.

Purpose of the Study:

• To develop a novel, sequence- and site-specific artificial RNA cleaving molecule.
• To create an intercalative molecule with a polyamine moiety and DNA connecting function.

Main Methods:

• Design and synthesis of a trisamine-acridine-tethered DNA molecule.
• Investigating the molecule's binding to complementary RNA.
• Assessing the cleavage of the phosphodiester bond in RNA.

Main Results:

• The novel molecule is designed to bind to complementary RNA sequences.
• The molecule is expected to cleave the phosphodiester bond of RNA near the intercalator's position.

Conclusions:

• The trisamine-acridine-tethered DNA represents a promising approach for sequence-specific RNA cleavage.
• This artificial RNA cleaving molecule has potential applications in molecular biology and therapeutic interventions.
