Abstract

The antitumor activity of 2-crotonyloxymethyl-2-cyclohexenone (COMC-6) is not the result of the GSH conjugate (GSMC-6) formed inside tumor cells, as the diethyl ester prodrug form of GSMC-6 displays little antitumor activity with B16 melanotic melanoma in vitro (IC(50) > 460 microM) versus COMC-6 (IC(50) 0.041 microM) and its five- and seven-membered ring homologues. Antitumor activity probably results from a reactive intermediate that forms during conjugation of the COMCs with intracellular GSH.
