e0“In present work, the bioactivity guided fractionation of crude ethanol extract from leaves of C. pinnatifida led to isolation of two sesquiterpene lactones: arucanolide and calealactone C, which structures were established on the basis of spectroscopic analysis”
e3“Additionally, calealactone C presented low cytotoxicity for J774 macrophages (CC50 31.73 µg/mL), similar to positive controls and presented antiamastigote activity with EC50 of 4.24 µg/mL”
