title: Design, synthesis, and anti-tumor activity of (2-O-alkyloxime-3-phenyl)-propionyl-1-O-acetylbritannilactone esters.
abstract: The extracts of Inula britannica have anti-inflammatory, anti-bacterial, anti-hepatitic, and anti-tumor activities. Various sesquiterpene lactones with cytotoxic properties including 1-O-acetylbritannilactone (1) have been isolated from this Chinese medicinal plant. Eight derivatives of 1-O-acetylbritannilactone, (2-O-alkyloxime-3-phenyl)-propionyl-1-O-acetylbritannilactone esters were designed and synthesized. Four of these compounds were tested to show inhibitory activity on the growth of human leukemia HL-60 and cancer Bel-7402 cell lines.
