TAD-based Therapeutics

Novel tiazofurin adenine dinucleotide (TAD) analogues containing a substituent at the C2 of adenine ring have been synthesized as inhibitors of the two isoforms of human IMP-dehydrogenase. The 2-ethyl TAD analogue was found to be the most potent. It did not inhibit other cellular dehydrogenases up to 50 ┬ÁM. Mycophenolic adenine bis(phosphonate)s containing the 2-phenyl and 2-ethyl group  were prepared as metabolically stable compounds, both nanomolar inhibitors. These compounds inhibited proliferation of leukemic K562 cells more potently than tiazofurin or mycophenolic acid.  The researchers are using the BMSDL for this project.
