Abstract

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 mouse lymphocytic leukemia P-388. When mice inoculated with 10(6) leukemic cells were treated with the drug during 9 days, their life span increased 80% over the control animals. Identification spectral data (uv, ir, 1H NMR, and MS) of the compound obtained by synthesis are given.
