General procedure for preparing mono- (3a-g) and disubstituted 1,4-naphthoquinones
(4a-d, 4f-g) from 2,3-dichloro-1,4-naphthoquinone
Numerous therapeutic drugs, in particular antitumor compounds, are quinone-bearing molecules including anthracyclines (doxorubicin, mitoxanthrone, and daunarubicin), benzoquinones (mitomycin C, geldanamycin), orthonaphthoquinones like [beta]-lapachone, and several synthetic compounds which are currently under clinical trials using 1,4-naphthoquinone
as pharmacophore group [6-9].
Previous studies on the anticancer activities of this 1,4-naphthoquinone
derivative are mostly focused on its cytotoxic properties via the induction of apoptosis and necrosis (Ding et al.
