Graduate Research Work
Recent studies have revealed that short interfering RNAs (siRNAs) have to be chemically modified to be useful in pre-clinical design and for therapeutic agents. This is to optimize their enzymatic stability, potency, cellular uptake, biodistribution, and pharmacokinetics. My research is one of the major research interests in Rozners’ lab focusing on the synthesis of monomeric building blocks for synthesis of amide-linked backbone as a neutral and hydrophobic mimic of the natural phosphodiester linkages in RNAs for their potential use in siRNAs. Our specific aim entails the improved synthesis of monomeric building blocks of amino acids and ultimate construction of optimized manual and automated solid-phase coupling of consecutive amide linked siRNAs. The major hands-on experiences acquired are proper organic synthesis techniques in the hood including column chromatography, optimization and scale-up multiple-steps of synthetic routes, adequate understanding and use of UV-Vis Spectrometer, RNA/DNA Synthesizer, and HPLC. Testing the effects of amide-linked siRNAs on activity and cellular uptake is performed through collaboration with Thermo Fisher Scientific. Conformation aspects of the sequences are also done through collaboration with Rochester University.
