title: Nitrogen-containing phorbol esters from Croton ciliatoglandulifer and their effects on cyclooxygenases-1 and -2.
abstract: Four new phorbol derivatives, 12-O-[(2R)-N,N-dimethyl-3-methylbutanoyl]-4-deoxyphorbol 13-acetate (1), 12-O-[(2S)-N,N-dimethyl-3-methylbutanoyl]-4-deoxyphorbol 13-acetate (2), 12-O-[3-methyl-2-butenoyl]-4-deoxyphorbol 13-acetate (3), and 12-O-[(2R)-N,N-dimethyl-3-methylbutanoyl]phorbol 13-acetate (4), along with six known compounds, were isolated from the aerial parts of Croton ciliatoglandulifer. An anti-inflammatory activity of a hexane extract of this plant was demonstrated against ear edema in mice produced by 12-O-tetradecanoylphorbol 13-acetate, and compounds 1, 4, and 3beta-O-acetyloleanolic acid (5) were active when evaluated against cyclooxygenases-1 and -2.
