The structures of the products were established mainly by NMR analysis, including 2D experiments. Biological activities of these products were evaluated against Artemia salina, Aedes aegypti and cytotoxicity using A549 human breast cells. %K lapachol %K enamine derivatives %K biological activities %U http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0001-37652002000200004
