dc.description.abstractHerein are documented our efforts in two projects, beginning with studies toward elucidating the biosynthesis of prenylated indole alkaloids from two different Aspergillus species. Marine-derived Aspergillus sp. and terrestrial-derived Aspergillus versicolor were found to produce antipodal metabolites, in which we have developed several putative biosynthetic pathways to determine the enantio-diverging point of these fungal cultures. Through the synthesis of several potential intermediates, both with and without isotopic labeling, as well as through bioinformatics analysis of both the (-)- and (+)-notoamide biosynthetic gene clusters, significant progress has been made toward identifying a single biosynthetic precursor that serves as an intermediate to the postulated enantio-diverging event, the intramolecular hetero Diels-Alder cycloaddition. In the second project discussed, through collaboration with Dr. James Berenson at the University of California, Los Angeles, we have developed a novel tumor specific drug delivery system. Two naphthyridine-drug derivatives were synthesized and conjugated to a modified DNA oligonucleotide specifically targeted for multiple myeloma cells. The oligonucleotide-drug conjugate was successfully delivered and activated specifically within RMI8226 multiple myeloma cells.
