生物活性
描述 Isoalantolactone, a sesquiterpene lactone compound that can be purified from the roots of Inula helenium L, with antifungal, anti-bacterial, anti-helminthic and anti-proliferative properties. In vitro, Isoalantolactone enhanced the radiosensitivity of UMSCC-10A cells; the sensitivity enhanced ratios (SERs) were 1.44 and 1.63, respectively, for 2.5 and 5 μM[5]. Treating SK-MES-1 cells with 0, 20, and 40 M of Isoalantolactone for 24 h change its morphology: rounded and shrunken cells, and decreased number of cells, the IC50 values were about 40 μM after 24 h treatment[4].
