9-Hydroxyellipticine is a derivative of ellipticine with diverse biological activities.1,2,3 It inhibits aroclor-induced activation of aniline hydroxylase, aminopyrine N-demethylase, and 7-ethoxycourmarin O-deethylase in rat liver microsomes (Kis = 3.5, 0.6, and 0.74 μM, respectively).1 9-Hydroxyellipticine inhibits the growth of L1210 murine leukemia cells (IC50 = 3 nM) in vitro and increases survival in an L1210 mouse leukemia model.2,3 It inhibits carrageenan-induced edema and UV-induced erythema in guinea pigs.4
