Description of Research
The inhibition of critical enzymes in nucleotide metabolism and DNA synthesis can be used as a chemotherapeutic approach to treating many diseases. DNA encodes information by forming specific patterns of methylation, and since gene expression is determined by “reading” these patterns during DNA-protein interactions, disruption of DNA methylation becomes an attractive target for therapy. Disruption of DNA methylation can be accomplished in several ways; in particular, by inhibition of DNA methyltransferase (DNA Metase) and/or S-adenosylhomocysteine hydrolase (SAHase), both established cellular targets for antiviral, antiparasitic and anticancer agents. My research focuses on the design and synthesis of modified nucleosides used to inhibit these essential enzymes.
