The cytotoxicity of ellipticine is determined by MTT test. Ellipticine (NSC 71795) is dissolved in DMSO (1 mM) and diluted in culture medium to final concentrations of 0, 0.1, 1, 5 or 10 μM. Cells in exponential growth are seeded at 1×104 per well in a 96-well microplate. After incubation the MTT solution is added, the microplates are incubated for 4 hours and cells lysed in 50% N,N-dimethylformamide containing 20% of sodium dodecyl sulfate (SDS), pH 4.5. The absorbance at 570 nm is measured. The mean absorbance of medium controls is subtracted as a background. The viability of control cells is taken as 100% and the values of treated cells are calculated as a percentage of control. The IC50 values are calculated using linear regression of the dose-log response curves.

IC50 = 0.99 μM for L1210 lymphocytic leukemia cells 
Plant alkaloid ellipticine shows antitumor, mutagenic and cytotoxic activities by inhibition of DNA topoisomerase II activity. DNA topoisomerase II regulates the overwinding or underwinding of DNA by cuting DNA double helix, passing another unbroken DNA helix through it, and then reannealing the cut strands.
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 . Ellipticine showed growth inhibition activity on L1210 lymphocytic leukemia cells with a IC50 of 0.99 μM .
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 .
Clinical trial: Several ellipticine derivatives have been validated in clinical trials, however, due to adverse side-effects, no progress has be reported.
