Interceptive effect of Lapachol in rats.

Abstract

Lapachol is a naphtoquinone with therapeutic potential against Chagas disease and is also used as an antimalarial agent. To study the reproductive toxicity potential of Lapachol, pregnant Wistar rats were treated with 0.5 mL of distilled water (control group), 0.5 mL of hydroalcoholic solution (vehicle group), or 20 mg of Lapachol in 0.5 mL of hydroalcoholic solution (treated group) by oral gavage from the 8th to the 12th day of pregnancy. The following variables were observed: maternal body weight on days 1, 6, 15, and 21; food intake on days 2, 6, 15, and 21 of pregnancy. The number of live and dead fetuses and the sites of resorptions were counted. The ovaries were weighed and the corpora lutea were counted. Data were analyzed by ANOVA one-way Dunnett test and chi 2 test. Results showed that mothers were uneffected but there was 100% fetal/embryo mortality, indicative of a strong interceptive effect of Lapachol in rats.
