A series of hydroxy-, oximino-, lactame, arylidene, N-methylpiperazinyl amide, isoxazole, pyrimidine derivatives of dipterocarpol, quinopimaric, and dammarenolic acids were synthesized and evaluated for cholinesterase inhibitory activity and cytotoxicity. All of the compounds were weak inhibitors for the enzyme acetylcholinesterase while being no inhibitor for butyrylcholinesterase. Dihydroquinopimaric acid was cytotoxic especially for A375 and A2780 tumor cells while being significantly less cytotoxic for nonmalignant fibroblasts (NIH 3T3).
