ABSTRACT
Aza-deoxi-pterocarpans (1) were synthesized through palladium-catalyzed aza-arylation of dihydronaphtalen, and showed antineoplastic effect on MDR leukemic cell lines (K562, Lucena-1 and FEPS). Compounds 1c-d were prepared to identify the pharmacophoric group responsible for the activity as well as compounds 2a-c were prepared to evaluate the structural requirements in the D-ring. LQB-223 (1b) is the most promising antileukemic agent since it was the most active on MDR cells without detectable toxicity to normal immune system cells.
