Abstract

Pterocarpanquinones (1a-e) and the aza-pterocarpanquinone (2) were synthesized through palladium catalyzed oxyarylation and azaarylation of conjugate olefins, and showed antineoplasic effect on leukemic cell lines (K562 and HL-60) as well as colon Cancer (HCT-8), gliobastoma (SF-295) and melanoma (MDA-MB435) cell lines. Some derivatives were prepared (3-8) and evaluated, allowing establishing the structural requirements for the antineoplasic activity in each series. Compound 1a showed the best selectivity index in special for leukemic cells while 2 showed to be more bioselective for HCT-8, SF-295 and MDA-MB435 cells. Pterocarpanquinones 1a and 1c-e, as well as 8 were the most active on amastigote form of Leishmania amazonensis in culture. Compounds 1a, 1c and 8 showed the best selectivity index.
