We assessed if andrographolide, incubated for 24 h, can induce cytotoxicity asmeasured by theMTTassay in Jurkat cells. Andrographolide reduced the percentage of MTTpositive cells in a dose-dependentmanner. This could be explained by a reduced proliferation as well as reduction in cell viability, since MTT measures mitochondrial activity. In
order to assess if andrographolide alter the cell viability we performed FACS analysis using Annexin V-FITC/Propidium Iodide Staining. We demonstrated that this compound did not induce a significant apoptosis at doses of 10 and 50 μM of andrographolide, however 100 μM of andrographolide increased significantly the early apoptosis (P
