| Hazard Information | Back Directory | [Description]
Ellipticine is an alkaloid isolated from Apocyanaceae plants that exhibits antitumor activities by intercalating into DNA and/or inhibiting DNA topoisomerase II.1,2,3 It forms covalent adducts in DNA after being enzymatically activated with cytochrome P450 isoforms (e.g., CYP3A4, CYP1A1, or CYP1A2) or by peroxidases in target tissues.2,3 Ellipticine has been shown to inhibit the proliferation of human breast adenocarcinoma MCF-7 cells, leukemia HL-60 and CCRF-CEM cells, neuroblastoma IMR-32, UKF-NB-3, and UKF-NB-4 cells, and U87MG glioblastoma cells with IC50 values ranging from 0.27-4.7 μM.2 | [Uses]
Ellipticine is a DNA intercalating agent and exhibits antitumor activities. | [Definition]

A topoisomerase II inhibitor. Acts as an intercalative alkaloid that stimulates topoisomerase II-mediated DNA breakage. Is also capable of uncoupling mitochondrial oxidative phosphorylation. | [Biochem/physiol Actions]
Cell permeable: yes | [in vitro]
treatment mammalian dna topoisomerase ii reaction mixture with ellipticine resulted in the stimulation of dna cleavage. the drug-stimulation of dna cleavage is related to the formation of a ternary complex between topoisomerase ii, dna, and ellipticine. ellipticine dose not inhibit enzyme-mediated dna religation, however, it stimulates dna breakage by enhancing the forward rate of cleavage [2]. ellipticine showed growth inhibition activity on l1210 lymphocytic leukemia cells with a ic50 of 0.99 μm [1]. | [in vivo]
ellipticine was evaluated in p. berghei infected mice in the 4-day suppressive test. ellipticine had a 100% inhibition versus controls on days 5 and 7 at an oral dose of 50 mg/kg/day, and the mean survival time (mst) was more than 40 days [3]. | [IC 50]
= 0.99 μm for l1210 lymphocytic leukemia cells [1] | [Purification Methods]
This DNA intercalator is purified by recrystallisation from CHCl3 or MeOH and is dried in vacuo. The UV max values in aqueous EtOH/HCl are at 241, 249, 307, 335 and 426nm. [Marini-Bettolo & Schmutz Helv Chim Acta 42 2146 1959.] The methiodide has m 360o(dec), with UV (EtOH/KOH) at 223, 242, 251, 311, 362 and 432nm. [Goodwin et al.
