(1) and curine (4). The acetylation of chondrofoline (1) gave O-acetylchondrofoline (3). The dimeric structures of 1 and 2 were studied through variable-temperature 1HNMR spectroscopy at 25, 40, 60, and 80 °C and conformationalanalysis, using density functional theory employing the M06-2X functional and the 6-31G* basis set. The in vitro antitrypanosomal activity of compounds 1, 2, 3, and 4 against
