The Antineoplastic Quassinoids of Simaba cuspidata Spruce and Ailanthus grandis Prian

Abstract
The South American S. cuspidata Spruce and North Indian A. grandis Prain were investigated as sources of potentially useful antineoplastic agents. Both of these Simaroubaceae plant species produce 6.alpha.-tigloyloxychaparrinone (4a) and the new quassinoid 6.alpha.-tigloyloxychaparrin (3b). The latter structure was determined by interpretation of spectral data and oxidation to 6.alpha.-tigloyloxychaparrinone (4a). While glycol 3b and .alpha.-ketol 4a significantly inhibit growth of the murine P388 lymphocytic leukemia cell line, only the .alpha.-ketol (4a) inhibited growth of the corresponding in vivo system.
