Aminoparthenolides as novel anti-leukemic agents: Discovery of the NF-κB inhibitor, DMAPT (LC-1)

A series of aminoparthenolide analogs (6-37) were synthesized and evaluated for their anti-leukemic activity. Eight compounds exhibited good anti-leukemic activity with LD50's in the low mu M range (1.5-3.0 mu M). Compounds 16, 24 and 30 were the most potent compounds in the series, causing greater than 90% cell death at 10 mu M concentration against primary AML cells in culture, with LD50 values of 1.7, 1.8 and 1.6 mu M.
