RESUMO
Cucurbatacins are known to produce cytotoxic and anticancer activities. Two novel norcucurbitacin glucosides (Wvl and Wv2) have recently been isolated from a purified fraction obtained from the rhizome of Wilbrandia verticillata. The present study evaluates the cytotoxic and anti-tumour activities of the norcucurbitacins. We have found a regular cytotoxicity in KB cells (Cy50 = 12µg/ml) as well as a significant inhibition in the Walker 256 carcinosarcoma growth (approximately 75%).
