EFL3 of lathyrane diterpenoids showed potent cytotoxicity to A549 cells. Furthermore, EFL3 induced apoptosis of A549 cells through mitochondrial pathway with involvement of loss of ΔΨm, release of cytochrome c.
The cytotoxicity of EFL3 was determined by an MTT assay to evaluate its antitumor activity. The results showed that EFL3 inhibited cell proliferation in a concentration-dependent manner in A549 cells after 72 h treatment. The IC50 of EFL3 for A549 cells was 34.04 ± 3.99 μM. The data suggested that EFL3 exhibited potent cytotoxicity towards these cells.
The results showed that EFL3 showed more potent cytotoxicity to A549 cellsMolecules 2011, 16 3225 than EFL1 (P < 0.01).
