Lapachol [2-hydroxy-3-(3-methyl-2-butenyl)-1,4-naphthoquinone] and its analogs [2-(3,7-dimethyl-2,6-octadienyl)-3-hydroxy-1,4-naphthoquinone and 2-(3,3-dibromo-2-propenyl)-3-hydroxy-1,4-naphthoquinone] have been described, among almost a hundred synthesized analogs, as active against rat tumor Walker 256 carcinosarcoma. The acetylglucosylation of lapachol results in a compound which extends lapachol activity becoming effective against
