Özet:  In the search for novel cytotoxic agents, sesquiterpenoids and phenylpropanoids have provided interesting lead compounds. From the chloroform extract of the underground parts of Laserpitium latifolium , the daucane sesquiterpenoids laserpitin and acetyldesoxodehydrolaserpitin, and the phenylpropanoids laserin and latifolon were isolated as the major compounds. Acetyldesoxodehydrolaserpitin is identified for the first time in the genus Laserpitium. Using a MTT and a sulforhodamine B (SRB) assay, the cytotoxic and antiproliferative activity of the extract and compounds laserpitin, acetyldesoxodehydrolaserpitin and laserin was tested in two closely related human breast adenocarcinoma cell lines, ie. the invasive MCF 7/6 and the non-invasive MCF 7/AZ. The IC 50 values of the extract were in the range of 184.72 – 397.16 μg/mL, with the most potent effect observed in the MTT test on the MCF 7/6 line. Among the tested compounds, acetyldesoxodehydrolaserpitin exerted a most potent, concentration-dependent effect (IC 50 values of 0.60 and 0.51 m M in the MCF 7/6 cell line, and 2.29 m M and 31.87 m M in the MCF 7/AZ cell line in the MTT and SRB test, respectively). The effect of laserin was more pronounced in the MTT test (IC 50 of 4.57 and 2.46 m M in the MCF 7/6 and MCF 7/AZ, respectively).
